宫腔内人工授精(IUI)虽常用于不育症的治疗,但相应精液指标尚未真正明确。本文采用严格的形态学判断标准,研究形态学正常精子水平与IUI成功率间的关系。 193例妇女,共538个IUI周期。使用克罗米芬(CC)、人绝经期促性腺激素(hMG)、或CC+hMG刺激卵泡。在使用hMG或CC+hMG的周期中,在IUI前24～36h,用人绒毛膜促性腺激素(hCG)刺激排卵。以停经后血清或尿hCG阳性,IUI后28d阴道超声见有胚囊,诊断妊娠。 使用电子计算机辅助精液分析系统计数 Intrauterine insemination (IUI) is often used in the treatment of infertility, but the corresponding semen index has not really clear. In this paper, strict morphological criteria to determine the normal morphological normal sperm level and the relationship between the success rate of IUI. 193 women, 538 IUI cycles in total. Follicles are stimulated with clomiphene citrate (CC), human menopausal gonadotropin (hMG), or CC + hMG. In cycles using hMG or CC + hMG, ovulation was stimulated with human chorionic gonadotropin (hCG) 24 to 36 h before IUI. To postmenopausal serum or urine hCG positive, 28 days after IUI vaginal ultrasound see embryo sac, diagnosis of pregnancy. Counts using a computer-aided semen analysis system
