Methods： aphrodisiac potential of the aqueous extract of Fadogia The aqueous stem extract of the plant was screened for phytochemical constituents. Male rats were orally dosed with 18 mg/kg, 50 mg/kg and 100 mg/kg body weight, respectively, of the extract at 24 h intervals and their sexual behavior parameters and serum testosterone concentration were evaluated at days 1, 3 and 5. Results： Phytochemical screening revealed the presence of alkaloids and saponins while anthraquinones and flavonoids are weakly present. All the doses resulted in significant increase in mount frequency, intromission frequency and significantly prolonged the ejaculatory latency （P 〈 0.05） and reduced mount and intromission latency （P 〈 0.05）. There was also a significant increase in serum testosterone concentrations in all the groups in a manner suggestive of dose-dependence （P 〈 0.05）. Conclusion： The aqueous extract of Fadogia agrestis stem increased the blood testosterone concentrations and this may be the mechanism responsible for its aphrodisiac effects and various masculine behaviors. It may be used to modify impaired sexual functions in animals, especially those arising from hypotestosteronemia.展开更多

One of such botanicals is Phoenix dactylifera in which the pollen grain has been acclaimed to be used as an aphrodisiac. However, the validity has not been scientifically tested. Dopamine is known to facilitate male sexual function. Therefore, the present study was undertaken to evaluate the effect of aqueous extract of Phoenix dactylifera pollen on the sexual behavior of male rats and to measure of serum Estradiol and Testostrone. Also, dopamine transmission in the nucleus accumbence (NAc) was studied in male rats using in vivo microdialysis. Methods and Materials: sixty male rats were randomized into 6 groups (A-F). Group A received 0.2 ml of Normal Saline mixed with Dimethyl Sulphate (DMSO), while groups B-F were injected same volume containing 35 mg/kg, 70 mg/kg, 105 mg/kg, 140 mg/kg and 350 mg/kg of DPP extract, respectively. Sexual behavioral parameters including mounting, intromission and ejaculation frequencies and latencies were recorded in male rats one hour after injection of extract by mating with a receptive female (1:1). The male serum testosterone and estradiol concentrations were also determined. Results: All doses stimulated male sexual behavior. Extract significantly increased mount, ejaculation, intromission frequencies and ejaculation latency in comparison to controlled ones (p 0.001). Mount and intromission latencies significantly reduced (p 0.001). Maximum effect was observed in dose 140 mg/kg. This extract was found to enhance Testestrone, Estradiol and the orientation of males toward female ones by increasing mounting and ano-genital investigatory behavior. Conclusions: Data from this study identified that the aqueous extract of Phoenix dactylifera pollen grain enhanced sexual behaviour in male rats. The improved sexual appetitive behaviour in male rats may be attributed, to the alkaloids, saponins, and or flavonoids since these phytochemicals has engorgement, androgen enhancing. Also, our findings support the traditional use of this plant as acclaimed aphrodisiac and for the treatment of pre-ejaculation and impotency.展开更多

METHODS： Thirty female rats were assigned into five groups of six animals each, such that rats in groups A, B, C, D and E received orally 1 mL of distilled water only, 5.7 mg/kg body weight （BW） of Exus Ginseng （a polyherbal formulation）, 25, 50 and 100 mg/kg BW of AEAML, respectively. After 1 h of treatment, female sexual behaviour parameters were monitored for 30 min. Luteinizing hormone （LH）, follicle stimulating hormone （FSH）, estradiol （E） and testosterone were also determined using standard methods. RESULTS： Six secondary metabolites were detected in AEAML with alkaloids （13.00 mg/L） being the highest. AEAML at 25 and 50 mg/kg BW significantly （P〈0.05） increased the darting frequency, hopping frequency, lordosis frequency, anogenital grooming, genital grooming and licking behaviour, whereas the darting latency, hopping latency and lordosis latency decreased （P〈0.05） in a manner comparable with Exus Ginseng. The 25 and 50 mg/kg BW of AEAML increased （P〈0.05） the serum concentrations of FSH, LH and E, like Exus Ginseng, whereas testosterone content was not altered （P〉0.05）. The 100 mg/kg BW of AEAML did not alter （P〉0.05） the sexual behaviour parameters, serum FSH, LH and E contents, whereas testosterone content increased significantly. The ovarian histology of the animals treated with Exus Ginseng, AEAML at 25 and 50 mg/kg BW revealed developing and ruptured follicles with numerous corpora lutea in the stroma, whereas the 100 mg/kg BW of AEAML produced fewer follicles and corpora lutea. CONCLUSION： The enhanced proceptive, receptive and orientation components of the female sexual behaviour by the 25 and 50 mg/kg BW of AEAML confers sexual invigorating potential on the plant. This study thus justifies the folkloric claim of the plant as a female aphrodisiac.展开更多

Methods: In this experiment, each male cohabitated with one female in a polysulfone cage. 30 ICR male mice were divided into 6 groups that received normal saline (the control group), 50 mg/kg, 100 mg/kg, 200 mg/kg, 500 mg/kg, and 1000 mg/kg body weight of Aquilaria subintegra leaf aqueous extracts orally for 21 days consecutively. Sexual behavior, percentage of pregnancy, number of offspring and male to female ratio of offspring in ICR mice were measured according to the established methods. Testosterone level was measured by using enzyme-linked immunosorbent assay. Results: Mice that received Aquilaria subintegra leaf aqueous extracts at 50 mg/kg body weight (day 0) had significantly higher mount frequency as compared to the control group;groups treated with 100, 500, 1000 mg/kg body weight extracts produced a greater number of offsprings when compared to the control group. All aphrodisiac parameters were similar between the treatment groups and the control group, indicating that Aquilaria subintegra leaf aqueous extract did not significantly alter the aphrodisiac parameters. Conclusions: Aquilaria subintegra leaf aqueous extracts have no effect on the aphrodisiac properties, but could increase the breeding rate in mice.展开更多

It is the most frequent at patients with cardiovascular and neurological diseases, sedentary lifestyle, arterial hypertension, diabetes, obesity and metabolic syndrome, and may disrupt their emotional life. But, sexual dysfunction may occur simply because of the physical aging of the body. Physiologic changes that occur with aging will aff ect sexual function and could be exacerbated by the above-mentioned diseases. Except for the sexual counseling and standard medications (phosphodiesterase type 5 (PDE5)– inhibitors, local estrogen therapy), some of the herbal medicines (aphrodisiacs) may be helpful in the treatment of these patients making them emotionally younger and happier. In this review, we bring a list of the pharmacologically tested aphrodisiac plants. But, we have a lack of information about their mechanisms of action, drug interaction and safety profi le. Until the relevant information is collected, uses of these products may be risky to the human being and should be prescribed only in consultation with a specialist.展开更多

Methods: Male rots were orally treated with 1500 mg/kg or 3000 mg/kg SS or ve-hicle, and their sexual behaviour was monitored 3 h later using a receptive female. Another group of rats was orallytreated with either 3000 mg/kg SS or vehicle for 7 consecutive days. Their sexual behaviour and fertility were evaluatedon days 1, 4 and 7 of treatment and day 7 post-treatment by pairing overnight with a pro-oestrous female. Results:The 1500 mg/kg dose, had a marked aphrodisiac action (prolongation of ejaculation latency) but no effect on libido(% mounting, % intromission and % ejaculation), sexual vigour (mounting-and-intromission frequency), or sexualperformance (intercopulatory interval). In contrast, the higher dose (3000 mg/kg) reversibly inhibited all the para?e-ten of sexual behaviour other than mounting-and-intromission frequency and copulatory efficiency. The effects of highdose SS were not due to general toxicity, liver toxicity, haemotoxicity, stress, muscle deficiency, muscle incoordina-fion, analgesia, hypoglycaemia or reduction in blood testosterone level. They were due to marked sedation. Conclu-sion: The kernel of T. catappa seeds has aphrodisiac activity and may be useful in the treatment of certain forms ofsexual inadequacies, such as premature ejaculation.展开更多
