Most patients with thrombosis that develops during pregnancy present with deep vein leg thrombosis and/or pulmonary embolism, whereas the development of mesenteric vein thrombosis(MVT) in pregnant patients is rare. We report a case of MVT in a 34-year-old woman who had achieved pregnancy via in vitro fertilization-embryo transfer(IVFET). At 7 wk of gestation, the patient was referred to us due to abdominal pain accompanied by vomiting and hematochezia, and she was diagnosed with superior MVT. Following resection of the gangrenous portion of the small intestine, anticoagulation therapy with unfractionated heparin and thrombolysis therapy via a catheter placed in the superior mesenteric artery were performed, and the patient underwent an artificial abortion. Oral estrogen had been administered for hormone replacement as part of the IVF-ET procedure, and additional precipitating factors related to thrombosis were not found. Pregnancy itself, in addition to the administered estrogen, may have caused MVT in this case. We believe that MVT should be included in the differential diagnosis of a pregnant patient who presents with an acute abdomen.展开更多

Methods A retrospective study was conducted with infertile women who underwent a total of 1 800 cycles of lVF-ET and intracytoplasmic sperm injection （ICSI） at the Reproductive Medicine Center of the Third Affiliated Hospital of Guangzhou Medical College from Jan. 2006 to Dec. 2007. The patients were divided into three groups based on age （year）. 〈30, 30-34 and 235. The rates of clinical pregnancy and multiple pregnancies were compared in each group when 1-3 embryos and 0-3 goodquality embryos were transferred respectively. Results 1） In the group of patients aged 〈30 years, there was no significant difference in pregnancy outcomes with 1-3 embryos transferred. However, pregnancy rates were similar when 2 3 good-quality embryos were transferred, which was significantly higher compared with 0-1 good-quality embryos transferred; the incidence of multiple pregnancies was not an issue when only 1 embryo was transferred. 2） The pregnancy rate of the patients aged 30 34 was not significant not only when only 2-3 embryos were transferred but also when 2-3 good-quality embryos were transferred, which was significant compared with when 1 embryo or 0 1 good-quality embryo was transferred. The subgroup of 3 good-quality embryos transferred, at the same time, was expected to significantly increase multiple pregnancy rate. 3） For the patients aged 235, there were similar pregnancy rates in the subgroup involving 1-3 embryos transferred. Compared with 0-2 good-quality embryos transferred, the pregnancy rate was significantly higher in the patients with 3 good-quality embryos transferred. An increased trend toward multiple pregnancies was observed among not only the subgroups with 1-3 embryos transferred, but also when 1-3 good-quality embryos were transferred, although it was significantly higher in patients with 3 good-quality embryo transferred. Conclusion In an effort to achieve the ideal pregnancy rate without the risk of multiple pregnancies, it is desirable to employ a single good-quality embryo transfer for patients aged 〈30 years and 2 good-quality embryos for patients aged 330. As older women （aged 335 years）, this is important, need to abstain from poor-quality embryo transferred by increasing the number of embryos transferred in an effort to improve the rate of clinical pregnancy, if the patients have had enough 2 high-quality embryos.展开更多
BACKGROUND The prevalence of female infertility between the ages of 25 and 44 is 3.5%to 16.7%in developed countries and 6.9%to 9.3%in developing countries.This means that infertility affects one in six couples and is ...BACKGROUND The prevalence of female infertility between the ages of 25 and 44 is 3.5%to 16.7%in developed countries and 6.9%to 9.3%in developing countries.This means that infertility affects one in six couples and is recognized by the World Health Organization as the fifth most serious global disability.The International Committee for Monitoring Assisted Reproductive Technology reported that the global total of babies born as a result of assisted reproductive technology procedures and other advanced fertility treatments is more than 8 million.Advancements in controlled ovarian hyperstimulation procedures led to crucial accomplishments in human fertility treatments.The European Society for Human Reproduction and Embryology guideline on ovarian stimulation gave us valuable evidence-based recommendations to optimize ovarian stimulation in assisted reproductive technology.Conventional ovarian stimulation protocols for in vitro fertilization(IVF)–embryo transfer are based upon the administration of gonadotropins combined with gonadotropin-releasing hormone(GnRH)analogues,either GnRH agonists(GnRHa)or antagonists.The development of ovarian cysts requires the combination of GnRHa and gonadotropins for controlled ovarian hyperstimulation.However,in rare cases patients may develop an ovarian hyper response after administration of GnRHa alone.CASE SUMMARY Here,two case studies were conducted.In the first case,a 33-year-old female diagnosed with polycystic ovary syndrome presented for her first IVF cycle at our reproductive center.Fourteen days after triptorelin acetate was administrated(day 18 of her menstrual cycle),bilateral ovaries presented polycystic manifestations.The patient was given 5000 IU of human chorionic gonadotropin.Twenty-two oocytes were obtained,and eight embryos formed.Two blastospheres were transferred in the frozen-thawed embryo transfer cycle,and the patient was impregnated.In the second case,a 37-year-old woman presented to the reproductive center for her first donor IVF cycle.Fourteen days after GnRHa administration,the transvaginal ultrasound revealed six follicles measuring 17-26 mm in the bilateral ovaries.The patient was given 10000 IU of human chorionic gonadotropin.Three oocytes were obtained,and three embryos formed.Two high-grade embryos were transferred in the frozen-thawed embryo transfer cycle,and the patient was impregnated.CONCLUSION These two special cases provide valuable knowledge through our experience.We hypothesize that oocyte retrieval can be an alternative to cycle cancellation in these conditions.Considering the high progesterone level in most cases of this situation,we advocate freezing embryos after oocyte retrieval rather than fresh embryo transfer.展开更多

Methods:The clinical data of 216 embryo transfer cycles with retrieved oocytes less than or equal to 5 during the procedure of IVF/ICSI in Reproductive Medicine Center of the 105th Hospital of PLA from Jul.2008 to Dec.2011 were analyze retrospectively.All the patients were divided into group A（< 35 years）,group B（35-39 years） and group C（≥40 years） according to the ages,and 409 IVF/ICSI cycles with patients’ age less than 35 years old and 6-15 retrieved oocytes in the same period were served as controlled group.Then the patients≥35 years were subdivided into gonadotropin-releasing hormone agonist（GnRH-a） long protocol group,GnRH-a short group and GnRH antagonist group according to the protocols of controlled ovarian hyperstimulation（COH）.The clinical date and the outcomes were analyzed and compared among all groups. Results:There were significantly differences in clinical pregnancy rate（38.3%vs.19.4%） and early abortion rate（16.1%vs.50.0%） between group A and group C（P<0.05）,and there were no significant differences in clinical pregnancy rate（38.3%vs.41.6%）and early abortion rate（16.1%vs.10.0%） between group A and control group（P>0.05）.There were no significant differences in clinical pregnancy rates（29.01%vs.26.1%vs.25.9%） and early abortion rates（33.3%vs.33.3%vs.40.0%） among GnRH-a long protocol group,GnRH-a short group and GnRH antagonist group（P>0.05）. Conclusions:Relatively satisfactory clinical outcomes of IVF/ICSI would still be got for the patients <35 years with retrieved oocytes less than or equal to 5,but whatever COH protocols such as GnRH-a long protocol,GnRH-a short and GnRH antagonist could not improve the outcomes of IVF/ICSI for the patients aged≥35 with retrieved oocytes less than or equal to 5.展开更多

Clinical data of 5217 patients who underwent IVF-ET were retrospectively analyzed. Patients were divided into the long-acting GnRH-a group (n=1330) and the short-acting GnRH-a group (w=3887) based on their various treatment plans. The clinical and laboratory embryo data and clinical pregnancy outcomes were compared between the two groups. The results showed that there were no significant differences in the age, infertility, primary/secondary infertility rate, IVF rate, body mass index (BMI), antral follicle counting (AFC), folliclestimulating hormone (FSH) level, and the number of transplanted embryos between the two groups (P>0.05). There were no significant differences in the oocyte numbers, M II rate, fertilization rate, cleavage rate and blastocyst formation rate (P>0.05) between the two groups. The gonadotropin (Gn) using days, Gn dose and endometrial thickness were significantly greater in the long-acting GnRH-a group than those in the short-acting GnRH-a group (P<0.01). Additionally, the estradiol (E2) levels, blastocyst freezing rate, embryo utilization rate, transplant cancellation rate and abortion rate were significantly lower in the long-acting GnRH-a group than those in the shortacting GnRH-a group (P<0.01). The clinical pregnancy rate and embryo implantation rate were significantly higher in the long-acting GnRH-a group than in the short-acting GnRH-a group (P<O.Ol). It was concluded that use of long-acting GnRH-a can effectively reduce the transplant cancellation rate and improve the clinical pregnancy rate of the fresh cycle.展开更多

However, whether IR in patients without PCOS should be treated remains uncertain. This study aims to clarify whether IR in patients without PCOS affects the outcomes of in-vitro fertilization-embryo transfer (IVF-ET) and pregnancy. Methods: Between January 2011 and December 2013, we retrospectively reviewed the medical records of 116 non-PCOS patients who underwent the first IVF–ET cycle. IR was calculated using the homeostasis model assessment (HOMA) index [HOMA-IR = (insulin × glucose)/405]. A HOMA index of >2.5 was used to indicate IR. Based on the HOMA index calculation, 28 patients were IR(+) and 88 patients had normal insulin sensitivity. We retrospectively compared the response with controlled ovarian hyperstimulation, retrieved oocytes number, fertilization rates, pregnancy rate, live birth rates, and gestational diabetes mellitus (GDM) incidence. Results: There were no significant differences in human menopausal gonadotropin administration, peak estradiol, retrieved oocyte number, fertilized embryo number, good quality embryo number, implantation rate, clinical pregnancy rate, miscarriage rate, delivery rate, or ovarian hyperstimulation syndrome and GDM incidences between the groups. Conclusion: IR in non-PCOS patients has no effect on IVF-ET outcomes or perinatal prognosis.展开更多

Methods The IVF-ET patients with complete fertilization failure （experimental group, n =32） were analyzed retrospectively. The patients whose oocytes retrieved at the same day and cultured on the same incubators with ≥ 50% fertilization rates were matched as the control （n=56）. Results The infertility duration, superovulation days, the rates of primary case, progesterone （P） level 〉3.12 nmol/L rate and rate of severe abnormal sperm （abnormal sperm rate 〉95%） in experimental group were significantly higher than those in the control （6.4 ±3.1 years, 12.6 ±2.2 d, 56%, 43%, 43% vs 4.6±2.9years, 11.6 ±% 1.3 d, 33%, 23%, 23%, respectively, P〈0.05）. Conclusion We should pay attention to these patients with primary infertility, longer infertility duration and superovulation days （〉6.4 years and 〉12.6 d） and having increased level of P on hCG injection day （〉3.12 nmol/L）, abnormal sperm rate 〉95% at the same time. They should be included in such patients at high risk of fertilization failure.展开更多

Methods Sixty-six patients with PCOS and undergoing IVF-ET were divided into two groups randomly, including an observation group （34 cases） and a control group （32 cases）. Ethinylestradiol and cyproterone acetate tablets and gonadotropin-releasing hormone agonist were administered for long-program superovulation in either group. In the observation group, the intervention of EA was applied to Guānyuán （关元 CV 4）, Zhōngjí （中极 CV 3）, Sānyīnjiāo （三阴交 SP 6）, Zǐgōng （子宫 EX-CA 1） and Tàixī （太溪 KI 3） additionally for 30 min, once daily, 1 menstrual cycle before controlled ovarian hyperstimulation （COH） and during COH. The pregnant outcome, evaluation of kidney deficiency syndrome, blood hormone level on the day of human chorionic gonadotropin injection and the concentrations of stem cell factor （SCF） in the serum and follicular fluid on the day of oocyte collection were compared between the two groups. Results The score of kidney deficiency symptoms was reduced remarkably after treatment in either group and the improvement in the observation group was superior to that in the control group （P0.01）. The fertilization rate [（76.25？±？20.33）% vs （66.34？±？15.44）%], cleavage rate [（98.66？±？3.70）% vs （94.47？±？9.45）%] and the rate of high-quality embryos [（60.20？±？22.20）% vs （50.55？±？16.15）%] in the observation group were all superior to those in the control group separately （all P0.05）. Clinical pregnancy rate （46.67%, 14/30） in the observation group was higher than that （37.93%, 11/29） in the control group, but without statistical difference （P0.05）. SCF concentrations in the serum and follicular fluid on the day of oocyte collection in the observation group were higher obviously than those in the control group （both P0.05）. Conclusion Electroacupuncture plays an active role in the pregnant outcomes of PCOS patients undergoing IVF-ET and it can relieve the symptoms of kidney deficiency in terms of TCM and improve clinical pregnant rate. The mechanism is relevant to the overall adjustment of organic endocrinal system and the local micro-environment of ovary and the improvement of oocyte quality through the up-regulation of SCF concentration.展开更多

It was unclear whether untreated PTB would affect pregnancy outcomes after IVF-ET.Method We conducted a retrospective cohort study of 14,254 infertile patients who had received IVFET at Peking University Third Hospital in 2017. Prior PTB was defined as the presence of signs suggestive of old or inactive PTB on CXR, with or without a clinical TB history. Patients who had prior PTB on CXR but had not received a clinical diagnosis and anti-TB therapy were included for analysis. Live birth,clinical pregnancy, and miscarriage rates were compared between the untreated PTB and non-PTB groups.Results The untreated PTB group had significantly lower clinical pregnancy(31.7% vs. 38.1%) and live birth(23.8% vs. 30.6%) rates than the non-PTB group(both P < 0.001). Multivariate analysis revealed that untreated PTB was a risk factor for decreased live birth rate [odds ratio(OR), 0.80;95% confidence interval(CI), 0.66–0.98;P = 0.028] in all patients and for increased miscarriage(OR, 4.19;95% CI,1.69–10.39;P = 0.002) and decreased live birth(OR, 0.45;95% CI, 0.24–0.83;P = 0.011) rates in patients with unexplained infertility.Conclusions Untreated PTB was associated with adverse pregnancy outcomes after IVF-ET, especially in patients with unexplained infertility, highlighting the clinical significance of PTB in this specific patient population.展开更多

According to the intervene treatment of in vitro Fertilization and Embryo Transfer(IVF-ET) long cycle scheme, the control group wait naturally for 3 months before IVFET. The dual therapy group take TCM prescriptionⅡ of cultivating emotion and assisting reproduction and auricular acupoint therapy for 3 months before IVF-ET, then Western Medicine treatment progestin supporting as well as auricular application and Antai Recipe after IVF-ET transplantation.The triple therapy group take TCM prescription Ⅱof cultivated emotion and assisted reproduction,auricular acupoint therapy and retention enema of TCM, and combination treatment the same as dual therapy group after transplantation. The natural pregnancy number, the period condition of secondary IVF-ET and the improvement of the kidney deficiency, liver depression and blood stasis syndrome among those three groups were compared.RESULTS: It was showed from analysis in 95 cases with ART failure that the number of natural preg-nancy was as followings: 3 patients from the dual therapy group, 10 patients from the triple therapy group, and no patient from the control group. The comparison among three groups have statistical significance(P < 0.05). The treatment group is superior to the control group, while the triple therapy is superior to the dual therapy. The comparison of the condition of the fertility rate, clinical pregnancy rate, biochemical pregnancy rate and early abortion rate during the period of secondary IVF-ET between pre-therapy and post-treatment of both the dual therapy group and the triple therapy group have statistical significance(P < 0.05). The comparison of the improvement of the kidney deficiency,liver depression and blood stasis syndrome between pre-therapy and post-treatment of both the dual therapy group and the triple therapy group have statistical significance(P < 0.05). The comparison between three groups after treatment have statistical significance(P < 0.05).CONCLUSION: TCM multi-channel interventional therapy can increase the natural pregnancy rate of patients with ART Failure(the triple therapy is superior to the dual therapy); it can increase the fertility rate, clinical pregnancy rate, and decrease the early abortion rate during the period of secondary IVF-ET; it can improve syndromes of kidney deficiency, liver depression and blood stasis.展开更多

文摘Pregnancy is an acquired hypercoagulable state. Most patients with thrombosis that develops during pregnancy present with deep vein leg thrombosis and/or pulmonary embolism, whereas the development of mesenteric vein thrombosis(MVT) in pregnant patients is rare. We report a case of MVT in a 34-year-old woman who had achieved pregnancy via in vitro fertilization-embryo transfer(IVFET). At 7 wk of gestation, the patient was referred to us due to abdominal pain accompanied by vomiting and hematochezia, and she was diagnosed with superior MVT. Following resection of the gangrenous portion of the small intestine, anticoagulation therapy with unfractionated heparin and thrombolysis therapy via a catheter placed in the superior mesenteric artery were performed, and the patient underwent an artificial abortion. Oral estrogen had been administered for hormone replacement as part of the IVF-ET procedure, and additional precipitating factors related to thrombosis were not found. Pregnancy itself, in addition to the administered estrogen, may have caused MVT in this case. We believe that MVT should be included in the differential diagnosis of a pregnant patient who presents with an acute abdomen.
文摘We read the Yang et al,published case report in Laparoscopic,Endoscopic and Robotic Surgery.2019.https://doi.org/10.1016/j.lers.2019.09.001,with great interest.Yang et al,in the introduction mentioned that the cornual ectopic pregnancy is defined as a pregnancy that is abnormally located in the proximal portion of the fallopian tube,lying within the muscular wall of the uterus.
文摘Objective To study the effect of patient age, the number and quality of embryos transferred on pregnancy outcome in in vitro fertilization-embryo transfer procedures （IVF-ETs）. Methods A retrospective study was conducted with infertile women who underwent a total of 1 800 cycles of lVF-ET and intracytoplasmic sperm injection （ICSI） at the Reproductive Medicine Center of the Third Affiliated Hospital of Guangzhou Medical College from Jan. 2006 to Dec. 2007. The patients were divided into three groups based on age （year）. 〈30, 30-34 and 235. The rates of clinical pregnancy and multiple pregnancies were compared in each group when 1-3 embryos and 0-3 goodquality embryos were transferred respectively. Results 1） In the group of patients aged 〈30 years, there was no significant difference in pregnancy outcomes with 1-3 embryos transferred. However, pregnancy rates were similar when 2 3 good-quality embryos were transferred, which was significantly higher compared with 0-1 good-quality embryos transferred; the incidence of multiple pregnancies was not an issue when only 1 embryo was transferred. 2） The pregnancy rate of the patients aged 30 34 was not significant not only when only 2-3 embryos were transferred but also when 2-3 good-quality embryos were transferred, which was significant compared with when 1 embryo or 0 1 good-quality embryo was transferred. The subgroup of 3 good-quality embryos transferred, at the same time, was expected to significantly increase multiple pregnancy rate. 3） For the patients aged 235, there were similar pregnancy rates in the subgroup involving 1-3 embryos transferred. Compared with 0-2 good-quality embryos transferred, the pregnancy rate was significantly higher in the patients with 3 good-quality embryos transferred. An increased trend toward multiple pregnancies was observed among not only the subgroups with 1-3 embryos transferred, but also when 1-3 good-quality embryos were transferred, although it was significantly higher in patients with 3 good-quality embryo transferred. Conclusion In an effort to achieve the ideal pregnancy rate without the risk of multiple pregnancies, it is desirable to employ a single good-quality embryo transfer for patients aged 〈30 years and 2 good-quality embryos for patients aged 330. As older women （aged 335 years）, this is important, need to abstain from poor-quality embryo transferred by increasing the number of embryos transferred in an effort to improve the rate of clinical pregnancy, if the patients have had enough 2 high-quality embryos.
文摘BACKGROUND The prevalence of female infertility between the ages of 25 and 44 is 3.5%to 16.7%in developed countries and 6.9%to 9.3%in developing countries.This means that infertility affects one in six couples and is recognized by the World Health Organization as the fifth most serious global disability.The International Committee for Monitoring Assisted Reproductive Technology reported that the global total of babies born as a result of assisted reproductive technology procedures and other advanced fertility treatments is more than 8 million.Advancements in controlled ovarian hyperstimulation procedures led to crucial accomplishments in human fertility treatments.The European Society for Human Reproduction and Embryology guideline on ovarian stimulation gave us valuable evidence-based recommendations to optimize ovarian stimulation in assisted reproductive technology.Conventional ovarian stimulation protocols for in vitro fertilization(IVF)–embryo transfer are based upon the administration of gonadotropins combined with gonadotropin-releasing hormone(GnRH)analogues,either GnRH agonists(GnRHa)or antagonists.The development of ovarian cysts requires the combination of GnRHa and gonadotropins for controlled ovarian hyperstimulation.However,in rare cases patients may develop an ovarian hyper response after administration of GnRHa alone.CASE SUMMARY Here,two case studies were conducted.In the first case,a 33-year-old female diagnosed with polycystic ovary syndrome presented for her first IVF cycle at our reproductive center.Fourteen days after triptorelin acetate was administrated(day 18 of her menstrual cycle),bilateral ovaries presented polycystic manifestations.The patient was given 5000 IU of human chorionic gonadotropin.Twenty-two oocytes were obtained,and eight embryos formed.Two blastospheres were transferred in the frozen-thawed embryo transfer cycle,and the patient was impregnated.In the second case,a 37-year-old woman presented to the reproductive center for her first donor IVF cycle.Fourteen days after GnRHa administration,the transvaginal ultrasound revealed six follicles measuring 17-26 mm in the bilateral ovaries.The patient was given 10000 IU of human chorionic gonadotropin.Three oocytes were obtained,and three embryos formed.Two high-grade embryos were transferred in the frozen-thawed embryo transfer cycle,and the patient was impregnated.CONCLUSION These two special cases provide valuable knowledge through our experience.We hypothesize that oocyte retrieval can be an alternative to cycle cancellation in these conditions.Considering the high progesterone level in most cases of this situation,we advocate freezing embryos after oocyte retrieval rather than fresh embryo transfer.
文摘Objective:To explore the clinical outcomes of the infertile women with retrieved oocytes less than or equal to 5 undergoing in vitro fertilization-embryo transfer（IVF-ET） or intracytoplasmic sperm injection（1CSI）. Methods:The clinical data of 216 embryo transfer cycles with retrieved oocytes less than or equal to 5 during the procedure of IVF/ICSI in Reproductive Medicine Center of the 105th Hospital of PLA from Jul.2008 to Dec.2011 were analyze retrospectively.All the patients were divided into group A（< 35 years）,group B（35-39 years） and group C（≥40 years） according to the ages,and 409 IVF/ICSI cycles with patients’ age less than 35 years old and 6-15 retrieved oocytes in the same period were served as controlled group.Then the patients≥35 years were subdivided into gonadotropin-releasing hormone agonist（GnRH-a） long protocol group,GnRH-a short group and GnRH antagonist group according to the protocols of controlled ovarian hyperstimulation（COH）.The clinical date and the outcomes were analyzed and compared among all groups. Results:There were significantly differences in clinical pregnancy rate（38.3%vs.19.4%） and early abortion rate（16.1%vs.50.0%） between group A and group C（P<0.05）,and there were no significant differences in clinical pregnancy rate（38.3%vs.41.6%）and early abortion rate（16.1%vs.10.0%） between group A and control group（P>0.05）.There were no significant differences in clinical pregnancy rates（29.01%vs.26.1%vs.25.9%） and early abortion rates（33.3%vs.33.3%vs.40.0%） among GnRH-a long protocol group,GnRH-a short group and GnRH antagonist group（P>0.05）. Conclusions:Relatively satisfactory clinical outcomes of IVF/ICSI would still be got for the patients <35 years with retrieved oocytes less than or equal to 5,but whatever COH protocols such as GnRH-a long protocol,GnRH-a short and GnRH antagonist could not improve the outcomes of IVF/ICSI for the patients aged≥35 with retrieved oocytes less than or equal to 5.

文摘Objective:To explore the effects of Zishen Yutai Pills(ZYPs)on the quality of oocytes and embryos,as well as pregnancy outcomes in patients with diminished ovarian reserve(DOR)receiving in vitro fertilizationembryo transfer(IVF-ET).The possible mechanisms,involving the regulation of bone morphogenetic protein 15(BMP15)and growth differentiation factor 9(GDF9),were also investigated.Methods:A total of 120 patients with DOR who underwent their IVF-ET cycle were randomly allocated to 2 groups in a 1:1 ratio.The patients in the treatment group(60 cases)received ZYPs from the mid-luteal phase of the former menstrual cycle by using gonadotropin-releasing hormone(Gn RH)antagonist protocol.The patients in the control group(60 cases)received the same protocol but without ZYPs.The primary outcomes were the number of oocytes retrieved and high-quality embryos.Secondary outcomes included other oocyte or embryo indices as well as pregnancy outcomes.Adverse events were assessed by comparison of the incidence of ectopic pregnancy,pregnancy complications,pregnancy loss,and preterm birth.Contents of BMP15 and GDF9 in the follicle fluids(FF)were also quantified with enzymelinked immunosorbent assay.Results:Compared with the control group,the numbers of oocytes retrieved and high-quality embryos were significantly increased in the ZYPs group(both P<0.05).After treatment with ZYPs,a significant regulation of serum sex hormones was observed,including progesterone and estradiol.Both hormones were up-regulated compared with the control group(P=0.014 and 0.008),respectively.No significant differences were observed with regard to pregnancy outcomes including implantation rates,biochemical pregnancy rates,clinical pregnancy rates,live birth rates,and pregnancy loss rates(all P>0.05).The administration of ZYPs did not increase the incidence of adverse events.The expressions of BMP15 and GDF9 in the ZYPs group were significantly up-regulated compared with the control group(both P<0.05).Conclusions:ZYPs exhibited beneficial effects in DOR patients undergoing IVF-ET,resulting in increments of oocytes and embryos,and up-regulation of BMP15 and GDF9 expressions in the FF.However,the effects of ZYPs on pregnancy outcomes should be assessed in clinical trials with larger sample sizes(Trial reqistration No.Chi CTR2100048441).
文摘Background:To investigate the factors associating with the cumulative clinical pregnancy outcome of in vitro fertilization-embryo transfer(IVF-ET)in women aged 35 years and older with normal ovarian reserve.Methods:A total of 358 patients undergoing IVF-ET at the Department of Reproductive Medicine,the First Affiliated Hospital of Xinjiang Medical University between January 2014 and June 2016 were analyzed by the Kaplan-Meier method and Cox proportional hazards model.Results:The probability of pregnancy in women 35-37 years of age and 38-40 years of age was 75.9%(95%confidence interval[CI]:75.1%-76.7%)and 66.9%(95%CI:65.6%-68.2%),respectively,and it was 37.8%(95%CI:34.7%-41.1%)in women aged 40 years and older.Univariate analysis(hazard ratio[HR]:2.50,95%CI:1.647-3.774)and multivariate analysis(HR:2.17,95%CI:1.427-3.268)showed a correlation between the number of retrieved oocytes and successful pregnancy.Conclusions:The number of retrieved oocytes plays a key role in the pregnancy outcome of women aged 35 years and older with normal ovarian reserve.We recommend the number of retrieved oocytes be increased for women aged 35 years and older with normal ovarian reserve.

文摘Objective: To observe the effects of electroacupuncture(EA) on reproductive outcomes in women with Shen(Kidndy) deficiency syndrome after in vitro fertilization-embryo transfer(IVF-ET),and explore the underlying molecular mechanism.Methods: Sixty-six infertile patients with Shen de?ciency syndrome undergoing IVF-ET were divided into EA or control groups according to a random table,33 cases in each group.Before undergoing IVF,patients in the EA and control groups received EA therapy and placebo needle puncture,respectively,for 3 menstrual cycles.Shen de?ciency syndrome scores were assessed.Other outcome measures included the number of retrieved oocytes and fertilization,high-quality embryo and clinical pregnancy rates.Follicular ?uid was collected on the day of oocyte retrieval,and granulosa cell expression of phosphatidylinositide3-kinases(PI3 K),serine-threonine kinase(Akt) and forkhead box O3(Foxo3 a) m RNA were measured by reverse transcribed and quantitative real-time polymerase chain reaction.Results: Syndrome scores for pre-versus post-treatments decreased significantly(16.53±1.75 to 8.67±1.61) in the EA group(P<0.05),but showed no signi?cant change in the control group(17.18±1.58 to 14.74±1.58).A signi?cant difference in score change was found between the EA and control groups(P<0.05).High-quality embryo and clinical pregnancy rates were both increased in the EA group compared with the control group [69.15%(195/282) vs.60.27%(176/292) and 66.67%(22/33) vs.42.42%(14/33),respectively,P<0.05].The fertilization rate was equivalent in EA and control groups.No difference was found in the number of retrieved oocytes between the two groups.Granulosa cell expression levels of PI3 K and Akt m RNA were signi?cantly increased in the EA group compared with the control group,while the expression of Foxo3 a was reduced(all P<0.05).Conclusions: For infertile patients with Shen de?ciency syndrome undergoing IVF,EA for tonifying Shen as an adjunct treatment may alleviate clinical symptoms and improve the high-quality embryo rate.The EA-induced mechanism may involve regulation of PI3 K/Akt/Foxo3 a expression in granulosa cells to improve the developmental microenvironment of oocytes and inhibit granulosa cell apoptosis,possibly contributing to the improved clinical pregnancy rate(Registration No.Chi CTR 1800016217).

文摘This study aimed to investigate the effect of different gonadotropin-releasing hormone agonist (GnRH-a) administration methods on pregnancy outcomes of patients undergoing in-vitro fertilization-embryo transfer (IVF-ET). Clinical data of 5217 patients who underwent IVF-ET were retrospectively analyzed. Patients were divided into the long-acting GnRH-a group (n=1330) and the short-acting GnRH-a group (w=3887) based on their various treatment plans. The clinical and laboratory embryo data and clinical pregnancy outcomes were compared between the two groups. The results showed that there were no significant differences in the age, infertility, primary/secondary infertility rate, IVF rate, body mass index (BMI), antral follicle counting (AFC), folliclestimulating hormone (FSH) level, and the number of transplanted embryos between the two groups (P>0.05). There were no significant differences in the oocyte numbers, M II rate, fertilization rate, cleavage rate and blastocyst formation rate (P>0.05) between the two groups. The gonadotropin (Gn) using days, Gn dose and endometrial thickness were significantly greater in the long-acting GnRH-a group than those in the short-acting GnRH-a group (P<0.01). Additionally, the estradiol (E2) levels, blastocyst freezing rate, embryo utilization rate, transplant cancellation rate and abortion rate were significantly lower in the long-acting GnRH-a group than those in the shortacting GnRH-a group (P<0.01). The clinical pregnancy rate and embryo implantation rate were significantly higher in the long-acting GnRH-a group than in the short-acting GnRH-a group (P<O.Ol). It was concluded that use of long-acting GnRH-a can effectively reduce the transplant cancellation rate and improve the clinical pregnancy rate of the fresh cycle.

文摘The ability of natural conception decreases with age,leading many advanced-age women with fertility desire begin to attempt in vitro fertilization and embryo transfer(IVF-ET)technique nowadays.Traditional Chinese medicine(TCM)believes that human body undergoes periodic changes corresponding to the natural rhythms.Women exhibit distinct physiological lunar rhythms of the thoroughfare vessel and the conception vessel,as well as pathological rhythms during the menstrual cycle and IVF-ET cycle.Based on the theory of TCM temporal rhythm,this paper discusses the pathogenesis characteristics of infertility in advanced-age women at different stages.It believes that acupuncture intervention should comply with the following ideas:determining main acupoints based on disease differentiation,with a preference for the acupoints on the thoroughfare vessel,the conception vessel,spleen meridian and kidney meridian,as well as the back-shu points of the liver,spleen and kidney;determining the supplementary acupoints based on syndrome differentiation and symptoms;determining the supplementary acupoints based on time differentiation of lunar rhythm of the thoroughfare vessel and the conception vessel,and integrating both reinforcing and reducing techniques.During the process of intervention,the physical and mental states were balanced simultaneously.
文摘Purpose: Insulin resistance (IR) plays an important role in the pathogenesis of polycystic ovary syndrome (PCOS);therefore, insulin-sensitizing agents are widely used to improve IR in women with PCOS. However, whether IR in patients without PCOS should be treated remains uncertain. This study aims to clarify whether IR in patients without PCOS affects the outcomes of in-vitro fertilization-embryo transfer (IVF-ET) and pregnancy. Methods: Between January 2011 and December 2013, we retrospectively reviewed the medical records of 116 non-PCOS patients who underwent the first IVF–ET cycle. IR was calculated using the homeostasis model assessment (HOMA) index [HOMA-IR = (insulin × glucose)/405]. A HOMA index of >2.5 was used to indicate IR. Based on the HOMA index calculation, 28 patients were IR(+) and 88 patients had normal insulin sensitivity. We retrospectively compared the response with controlled ovarian hyperstimulation, retrieved oocytes number, fertilization rates, pregnancy rate, live birth rates, and gestational diabetes mellitus (GDM) incidence. Results: There were no significant differences in human menopausal gonadotropin administration, peak estradiol, retrieved oocyte number, fertilized embryo number, good quality embryo number, implantation rate, clinical pregnancy rate, miscarriage rate, delivery rate, or ovarian hyperstimulation syndrome and GDM incidences between the groups. Conclusion: IR in non-PCOS patients has no effect on IVF-ET outcomes or perinatal prognosis.

文摘Objective To find the possible factors predicting fertilization failure of in vitro fertilization-embryo transfer （1VF-ET）. Methods The IVF-ET patients with complete fertilization failure （experimental group, n =32） were analyzed retrospectively. The patients whose oocytes retrieved at the same day and cultured on the same incubators with ≥ 50% fertilization rates were matched as the control （n=56）. Results The infertility duration, superovulation days, the rates of primary case, progesterone （P） level 〉3.12 nmol/L rate and rate of severe abnormal sperm （abnormal sperm rate 〉95%） in experimental group were significantly higher than those in the control （6.4 ±3.1 years, 12.6 ±2.2 d, 56%, 43%, 43% vs 4.6±2.9years, 11.6 ±% 1.3 d, 33%, 23%, 23%, respectively, P〈0.05）. Conclusion We should pay attention to these patients with primary infertility, longer infertility duration and superovulation days （〉6.4 years and 〉12.6 d） and having increased level of P on hCG injection day （〉3.12 nmol/L）, abnormal sperm rate 〉95% at the same time. They should be included in such patients at high risk of fertilization failure.

文摘Objective To observe the impacts of electroacupuncture （EA） on oocyte quality and pregnant outcome for the patients with polycystic ovary syndrome （PCOS） undergoing in vitro fertilization and embryo transfer （IVF-ET） and explore its potential mechanism. Methods Sixty-six patients with PCOS and undergoing IVF-ET were divided into two groups randomly, including an observation group （34 cases） and a control group （32 cases）. Ethinylestradiol and cyproterone acetate tablets and gonadotropin-releasing hormone agonist were administered for long-program superovulation in either group. In the observation group, the intervention of EA was applied to Guānyuán （关元 CV 4）, Zhōngjí （中极 CV 3）, Sānyīnjiāo （三阴交 SP 6）, Zǐgōng （子宫 EX-CA 1） and Tàixī （太溪 KI 3） additionally for 30 min, once daily, 1 menstrual cycle before controlled ovarian hyperstimulation （COH） and during COH. The pregnant outcome, evaluation of kidney deficiency syndrome, blood hormone level on the day of human chorionic gonadotropin injection and the concentrations of stem cell factor （SCF） in the serum and follicular fluid on the day of oocyte collection were compared between the two groups. Results The score of kidney deficiency symptoms was reduced remarkably after treatment in either group and the improvement in the observation group was superior to that in the control group （P0.01）. The fertilization rate [（76.25？±？20.33）% vs （66.34？±？15.44）%], cleavage rate [（98.66？±？3.70）% vs （94.47？±？9.45）%] and the rate of high-quality embryos [（60.20？±？22.20）% vs （50.55？±？16.15）%] in the observation group were all superior to those in the control group separately （all P0.05）. Clinical pregnancy rate （46.67%, 14/30） in the observation group was higher than that （37.93%, 11/29） in the control group, but without statistical difference （P0.05）. SCF concentrations in the serum and follicular fluid on the day of oocyte collection in the observation group were higher obviously than those in the control group （both P0.05）. Conclusion Electroacupuncture plays an active role in the pregnant outcomes of PCOS patients undergoing IVF-ET and it can relieve the symptoms of kidney deficiency in terms of TCM and improve clinical pregnant rate. The mechanism is relevant to the overall adjustment of organic endocrinal system and the local micro-environment of ovary and the improvement of oocyte quality through the up-regulation of SCF concentration.

文摘Objective:To explore the effect of different fertilization time after human chorionic gonadotropin(HCG)injection on the outcome of fertilization in vitro fertilization-embryo transfer(IVF-ET).Methods:One thousand one hundred and forty IVF-ET cycles from January 2016 to August 2018 were analyzed retrospectively.According to the different fertilization time after injection of HCG divided into four groups:Group A(38.0 h~39.0 h),Group B(39.1 h~40.0 h),Group C(40.1 h~41.0 h),and Group D(41.1 h~42.0 h).The normal fertilization rate,the normal cleavage rate,the embryo utilization rate,the high-quality embryo rate,the clinical pregnancy rate,the implantation rate,and the spontaneous abortion rate were analyzed among the groups.Then we investigated the effect of different promotion methods on the outcome of fertilization during the optimal fertilization time.Results:There was no significant difference in 2PN cleavage rate,available embryo rate,clinical pregnancy rate,implantation rate and abortion rate among the four groups(P>0.05).The high-quality embryo rate in Group D(44.6%)was the highest,and was significantly different among the four groups(P<0.05).The normal fertilization rate in Group D(71.6%)was the highest,and was significantly different among the four groups(P<0.05).The normal fertilization rate(78.1%)of antagonist group was significantly higher than other groups(P<0.05).Conclusion:The different fertilization time after HCG injection have effects on high-quality embryo rate and normal fertilization rate of patients in IVF-ET.The appropriate fertilization time of patients in IVF-ET was 41 h~42 h after HCG injection in our reproductive center,improved the clinical pregnancy rate and reduced the early abortion rate.The GnRH-ant protocol is superior to other protocol in IVF-ET.
文摘Objective To investigate the reproduction-assisting effects of laparoscopic ＂corepulling＂ salpingectomy for patients with hydrosalpinx on ovarian reserve,responsiveness to stimuli and outcomes of in vitro fertilization and embryo transfer（IVF-ET）.Methods Infertile females receiving treatment in Reproductive Medicine Center of Yantai Yuhuangding Hospital due to fallopian tube disorders（n=214） were enrolled from July 2006 to December 2007 and further divided into three groups.＂Core-pulling＂ procedure group（group A） consisted of patients receiving pretreatment with ＂corepulling＂ salpingectomy due to hydrosalpinx in our center（n=31）,wherein 16 patients received IVF-ET.Conventional procedure group（group B） consisted of patients receiving conventional salpingectomy for hydrosalpinx or ectopic pregnancy in our center or other institutes prior to IVF-ET（n=59）.Control group（group C） consisted of patients receiving IVF-ET without the history of previous hydrosalpinx or salpingectomy（n=124）.Results At baseline,the antral follicle count of group B was significantly less than that of groups A and C（8.6±2.5 vs 8.3±2.0 vs 9.8±2.4）.The mature oocytes retrieved numbered less than the other two groups,in a statistically significant manner compared with group C（13.1±5.7 vs 10.6±5.0 vs 12.0±6.2）.Patients of groups A and B received more gonadotropin while the dosage of group B differed significantly from group C（31.0±17.7 vs 37.6±8.3 vs 30.0±4.6）.E2 level on hCG injection day was slightly lower in group B than in the other two groups,statistically significant compared with that of group C,but not compared with that of group A.After receiving IVF-ET,patients of group A showed significantly higher conception rate than groups B and C（62.5% vs 43.6% vs 39.2%）.Conclusion Compared with the conventional procedure,laparoscopic ＂core-pulling＂ salpingectomy should be recommended for patients with hydrosalpinx intending to receive IVF-ET,which did not interfere with the ovarian reserve or responsiveness but improve the conception rate in clinical practice.

文摘Objective Prior pulmonary tuberculosis(PTB) on chest X-ray(CXR) was commonly found in infertile patients receiving examinations before in vitro fertilization and embryo transfer(IVF-ET). It was unclear whether untreated PTB would affect pregnancy outcomes after IVF-ET.Method We conducted a retrospective cohort study of 14,254 infertile patients who had received IVFET at Peking University Third Hospital in 2017. Prior PTB was defined as the presence of signs suggestive of old or inactive PTB on CXR, with or without a clinical TB history. Patients who had prior PTB on CXR but had not received a clinical diagnosis and anti-TB therapy were included for analysis. Live birth,clinical pregnancy, and miscarriage rates were compared between the untreated PTB and non-PTB groups.Results The untreated PTB group had significantly lower clinical pregnancy(31.7% vs. 38.1%) and live birth(23.8% vs. 30.6%) rates than the non-PTB group(both P < 0.001). Multivariate analysis revealed that untreated PTB was a risk factor for decreased live birth rate [odds ratio(OR), 0.80;95% confidence interval(CI), 0.66–0.98;P = 0.028] in all patients and for increased miscarriage(OR, 4.19;95% CI,1.69–10.39;P = 0.002) and decreased live birth(OR, 0.45;95% CI, 0.24–0.83;P = 0.011) rates in patients with unexplained infertility.Conclusions Untreated PTB was associated with adverse pregnancy outcomes after IVF-ET, especially in patients with unexplained infertility, highlighting the clinical significance of PTB in this specific patient population.

文摘BACKGROUND Intramural pregnancy is a rare type of ectopic pregnancy,which is diagnosed by transvaginal ultrasound and magnetic resonance imaging.Management strategies vary depending on the site of the pregnancy,the gestational age and the desire to maintain fertility.The incidence of intramural pregnancy in assisted reproductive technology is higher than that in natural pregnancy.CASE SUMMARY We present a case of intramural pregnancy after in vitro fertilization and elective single embryo transfer following salpingectomy.The patient was completely asymptomatic and her serumβ-human chorionic gonadotropin level increased from 290 m IU/m L to 1759 m IU/m L.Three-dimensional transvaginal ultrasound indicated a heterogeneous echogenic mass arising from the uterine fundus which was surrounded by myometrium and a slender and extremely hypoechoic area stretching to the uterine cavity which was thought to be a fistulous tract.Therefore,we considered a diagnosis of intramural pregnancy and laparoscopic surgery was conducted at 7 wk gestation.CONCLUSION Early diagnosis and treatment of intramural pregnancy is significant for maintaining fertility.

文摘OBJECTIVE: To evaluate the curative effect of Traditional Chinese Medicine(TCM) multi-channel interventional therapy on women with Assisted Reproductive Technology(ART) failure, to compare the curative effect of the dual therapy and triple therapy on women with ART Failure, and to choose the best TCM interventional therapeutic plan.METHODS: The 95 cases with ART Failure from West China second University Hospital of Sichuan University meeting the inclusion criteria were randomly divided into three groups:dual therapy group(31 cases), triple therapy group(33 cases)and control group(31 cases). According to the intervene treatment of in vitro Fertilization and Embryo Transfer(IVF-ET) long cycle scheme, the control group wait naturally for 3 months before IVFET. The dual therapy group take TCM prescriptionⅡ of cultivating emotion and assisting reproduction and auricular acupoint therapy for 3 months before IVF-ET, then Western Medicine treatment progestin supporting as well as auricular application and Antai Recipe after IVF-ET transplantation.The triple therapy group take TCM prescription Ⅱof cultivated emotion and assisted reproduction,auricular acupoint therapy and retention enema of TCM, and combination treatment the same as dual therapy group after transplantation. The natural pregnancy number, the period condition of secondary IVF-ET and the improvement of the kidney deficiency, liver depression and blood stasis syndrome among those three groups were compared.RESULTS: It was showed from analysis in 95 cases with ART failure that the number of natural preg-nancy was as followings: 3 patients from the dual therapy group, 10 patients from the triple therapy group, and no patient from the control group. The comparison among three groups have statistical significance(P < 0.05). The treatment group is superior to the control group, while the triple therapy is superior to the dual therapy. The comparison of the condition of the fertility rate, clinical pregnancy rate, biochemical pregnancy rate and early abortion rate during the period of secondary IVF-ET between pre-therapy and post-treatment of both the dual therapy group and the triple therapy group have statistical significance(P < 0.05). The comparison of the improvement of the kidney deficiency,liver depression and blood stasis syndrome between pre-therapy and post-treatment of both the dual therapy group and the triple therapy group have statistical significance(P < 0.05). The comparison between three groups after treatment have statistical significance(P < 0.05).CONCLUSION: TCM multi-channel interventional therapy can increase the natural pregnancy rate of patients with ART Failure(the triple therapy is superior to the dual therapy); it can increase the fertility rate, clinical pregnancy rate, and decrease the early abortion rate during the period of secondary IVF-ET; it can improve syndromes of kidney deficiency, liver depression and blood stasis.
