精子上游实验对少弱精症患者行宫腔内人工授精指导意义的观察

The value of sperm swimming test in intrauterine insemination in patients with oligospermia and asthenospermia

目的：探讨精子上游实验结果对少弱精症患者选择辅助生殖技术治疗方案的指导意义。方法：根据上游实验后精子浓度将202例行宫腔内人工授精（IUI）治疗的少弱精症患者分为≤1×10^6／ml组，〉1×10^6／ml～≤4×10^6／ml组，〉4×10^6／ml组，比较3组的妊娠结局。结果：202个周期共获得26个妊娠周期，总妊娠率为12．9％。3组妊娠率差异无统计学意义（P〉0．05）。结论：对于精液上游处理后精子浓度较小的少弱精症患者仍可进行IUI治疗。

Objective： To explore the value of sperm swimming test in assisted reproductive technology for patients with oligospermia and asthenospermia. Methods： A total of 202 patients who experinced sperm swimming test were divided into three groups according to the sperm density （not more than 1 x 106/ml, more than 1 ×10^6/ml but not more than 4 ×10^6/ml, and more than 4 ×10^6/ml）. The pregnancy outcomes were compared among three groups. Results： Among 202 patients, pregnancy occurred in 26 cycles. The overall pregnancy rate was 12.9%. There were no statistically differences in the pregnancy rate among these three groups （ P 〉 0.05 ）. Conclusion ： The poor sperm density after sperm swimming test are more likely to result in a pregnancy by intrauterine insemination for those with oligospermia and asthenospermia.
