目的讨论宫腔内人工授精(IUI)的临床妊娠率及其影响因素。方法用阴道B超监测卵泡发育及子宫内膜厚度情况,结合尿黄体生成激素(LH)峰判断排卵时间,用洗涤上游法处理精液,对我院2001年6月~2005年4月60例不孕症患者实施IUI。结果宫腔内人工授精的妊娠率为21.67%。女性年龄越轻,IUI妊娠率越高。卵泡直径的大小与子宫内膜的厚度对宫腔内人工授精的妊娠率有明显影响。结论女方年龄、子宫内膜的厚度和授精时机、促排卵方案等是影响宫腔内人工授精妊娠率的主要因素。
Objective To discuss the intrauterine insemination (IUI) clinical pregnancy rate and its influencing factors. Methods The development of ovarian follicles and the thickness of endometrium were monitored by vaginal ultrasonography. The time of ovulation was determined by combining with urine LH, and the semen was treated by the washing upstream method. The incidence of ovarian failure in our hospital from June 2001 to April 2005 was 60 Pregnant patients implement IUI. Results The intrauterine insemination rate of pregnancy was 21.67%. The younger women, IUI pregnancy rate higher. The size of the follicle diameter and the thickness of the endometrium on intrauterine insemination have a significant impact on the pregnancy rate. Conclusion Female age, endometrial thickness and timing of fertilization, ovulation induction programs are the main factors affecting intrauterine pregnancy rate of artificial insemination.
