【摘要】 目的:探讨夫精宫腔内人工授精(IUI)时注入宫腔内a+b级精子数对妊娠结局的影响。方法:回顾性分析192例女性不育症患者接受268个周期的夫精IUI治疗的临床资料。精液采用上游法洗涤。结果:周期妊娠成功率(PPR)在注入宫腔内a+b级精子数≤1×106时8个周期无一例妊娠,(1~5)×105时为10.34%,(5~10)×106时为27.78%,(10~15)×106时为26.10%,(15~20)×106时为24.00%,(20~25)×106时为23.08%,>25×106时为20.59%。结论:IUI时注入宫腔内的a+b级精子数在(5~15)×106时PPR最高,并非随着注入宫腔内的a+b级精子数的增多而PPR增高。更多还原

【Abstract】 Objective: To explore the effect of the count of a + b class sperm through intrauterine injection on pregnancy outcome when intrauterine insemination(IUI) with her husband’s semen was performed.Methods: Analysis of clinical data of 192 female infertility patients receiving IUI with her husband’s semen for 268 cycles was made retrospectively.Swimming-up method was used to wash semen.Results: Regarding the period pregnancy rate of intrauterine insemination,no pregnancy was found in 8 cycles when the count of a + b class sperm ≤1×106;the pregnancy rate was 10.34% at(1 ~ 5)×105;27.78% at(5 ~10)×106;26.10% at(10 ~15)×106;24.00% at(15 ~ 20)×106;23.08% at(20 ~ 25)×106 and 20.59% when the count >25×106.Conclusion: The period pregnancy rate was the highest when the count of a + b class sperm through intrauterine injection was at(5 ~ 15)×106 when IUI was performed,but it is not increased with the increasing of the count of a + b class sperm.更多还原
