目的: 分析影响宫腔内人工授精( intrauterine insemination，IUI) 成功率的相关影响因素，旨在更好地
指导临床工作。方法: 总结自2014－01 ～ 2015－03 360 个人工授精周期的妊娠率，分析影响其成功率的相关临床
因素。采用χ² 检验进行单因素分析，同时多因素分析采用Logistic 回归分析。结果: 周期临床妊娠率为12．77%，
促排卵周期临床妊娠率高于自然周期，卵泡≥2 个较单个卵泡成功率高( OR= 0．333，P= 0．006) ，单侧输卵管通畅
周期临床妊娠率低于其它周期( P＜0．05) 。结论: 输卵管因素、治疗方案是影响本中心人工授精妊娠结局的主要
因素。

the ovulation group， the clinical pregnancy rate was higher than the natural group．The group with more
than 2 dominant follicles had higher clinical pregnancy rate as compared with the single dominant follicle
group( OR= 0．333，P = 0．006) ．The pregnancy rate lower than other period clinical unilateral tubal
patency period( P＜0．05) ．The clinical pregnancy rate was no difference in female age、female people、
female occupation、infertile duration and cycles of IUI．Conclusion: The tubal factor and treatment plan
