目的探讨处理前后的精液特征对IUI妊娠率的影响。方法收集分析342例不育不孕患者共372个IUI治疗周期,检测记录每个周期精液处理前后的各精液参数,并按照妊娠结果分成两组:妊娠组与非妊娠组,按照处理后精子活动总数(PTMS)分成3组:PTMS<10×106/ml,10×106/ml≤PTMS<20×106/ml,PTMS≥20×106/ml。比较各组间的精液参数和IUI妊娠率。结果372个IUI周期共获得62例妊娠,总周期妊娠率是16.67%,总病例妊娠率是18.13%。妊娠组与非妊娠组各精液参数无明显差别;PTMS<10×106/ml组获得的妊娠率明显低于后两组(P<0.05)。结论当PTMS>10×106/ml时,IUI治疗周期才有可能获得较为理想的妊娠率。
Objective To investigate the effect of semen characteristics before and after treatment on pregnancy rate of IUI. Methods A total of 372 IUI treatment cycles were collected and analyzed in 342 infertility infertility patients. The semen parameters before and after semen processing were recorded and recorded. The semen parameters were divided into two groups according to the results of pregnancy: pregnancy group and non-pregnancy group. According to the post-treatment sperm motility The total number (PTMS) was divided into 3 groups: PTMS <10 × 10 6 / ml, 10 × 10 6 / ml ≦ PTMS <20 × 10 6 / ml, PTMS ≧ 20 × 10 6 / ml. The semen parameters and IUI pregnancy rates were compared between groups. Results A total of 62 pregnancies were obtained in 372 IUI cycles, with a total cycle pregnancy rate of 16.67% and a total pregnancy rate of 18.13%. Pregnancy group and non-pregnancy group semen parameters no significant difference; PTMS <10 × 106 / ml group pregnancy rate was significantly lower than the latter two groups (P <0.05). Conclusion When the PTMS> 10 × 106 / ml, IUI treatment cycle is possible to obtain a more satisfactory pregnancy rate.
