摘要
目的 :了解成都地区大学生的精子质量和生育能力的现状。方法 :采用计算机辅助精子分析 (CASA)技术 ,检查成都地区 12所高校 2 95名志愿者的精子密度、精子活率及 A级精子 ,以精子密度≥ 2 0× 10 6 / ml、活率≥ 5 0 %、 A级精子≥ 2 5 %为正常标准 ,统计调查结果。在精子质量正常者中随机选取 84人检查血清抗精子抗体 (As Ab)。结果 :2 95人精子密度、精子活率及 A级精子分别为 (5 3.2 1± 2 9.0 1)× 10 6 / m l、 (5 6 .5 9± 14 .2 3) %和 (33.98± 14 .0 9) % ,其中精子质量正常196人 (6 6 .4 4 % ) ,异常 99人 (33.5 6 % )。在精子质量异常的 99人中 ,90人精子活率和 /或 A级精子异常 (90 .91% ) ,18人精子密度异常 (18.18% ) ,9人精子密度、精子活率和 /或 A级精子异常 (9.0 9% ) ,未发现无精子者。随机抽查的 84人血清 As Ab (+)者 13人 ,占抽查人数的 15 .4 8%。结论 :成都地区大学生存在明显的精子质量问题 。
Objective:To acknowledge the status of the sperm quality and fertility of college students in Chengdu area. Methods:The sperm concentration, motility, and A grade sperm of 295 students were investigated by computer assisted sperm analysis (CASA) in 12 colleges of Chengdu and then analyzed according to the normal criterion (concentration ≥20×10 6/ml; motility≥50%; A grade sperm≥25%). And 84 students were sampled randomly from the students with normal sperm quality to test AsAb. Results: Among the 295 students, Concentration was 53 21±29 01(×10 6/ml), motility was 56 59±14 23(%) and A grade sperm was 33 97±16 02(%).The normal sperm rate was 66 44%(196/295), the abnormal rate was 33 36%. Among the 99 abnormal sperm students, there were 90 students (90 91%) with abnormal motility and/or A grade sperm, 18 students (18 18%) with abnormal concentration, 9 students (9 09%) with abnormal concentration, motility and/or A grade sperm. There were no students without sperm. 13 students (15 48%) of AsAb (+) were detected in 84 students. Conclusion: The obvious problem of sperm quality exists among the students in Chengdu area, and the effect of immunity to fertility should not be neglected. It is estimated that potential occurrence of infertility of the students should be higher than 12%~16% which was reported at present.
