目的:探讨影响夫精宫腔内人工授精(IUI)妊娠率的各种相关因素。方法:归纳分析本生殖中心552个周期夫精IUI的情况,并分析不孕类型、年龄、输卵管、方案(自然周期、促排周期)、每周期授精次数及注入宫腔内前向运动精子总数与妊娠率的关系。结果:552个周期中有100个周期获得了妊娠,妊娠率为18.12%,其中不孕类型、年龄、每周期授精次数与妊娠率无关(P>0.05),而双侧输卵管通畅、促排周期及处理后前向精子总数≥10×106的周期妊娠率明显升高(P<0.05)。结论:患者双侧输卵管通畅,使用促排卵治疗,处理后前向运动精子总数≥10×106,妊娠率明显提高。
Objective: To explore various factors that influence the intrauterine insemination (IUI) pregnancy rate. Methods: The situation of IUI in 552 cycles of fertility in our reproductive center was analyzed and analyzed. The types of infertility, age, fallopian tube, program (natural cycle, promoting cycle), the number of fertilization per cycle and the total amount of forward spermatozoon Relationship with pregnancy rate. Results: 100 cycles were obtained in 552 cycles and the pregnancy rate was 18.12%. The type of infertility, age and the number of insemination per cycle had no relation with pregnancy rate (P> 0.05), while bilateral tubal patency, (P <0.05), and the pregnancy rate of cycles with the total number of forward spermatozoa≥10 × 106 was significantly increased (P <0.05). Conclusion: The bilateral tubal patency in patients with ovulation induction treatment, the total number of forward-moving sperm after treatment ≥ 10 × 106, the pregnancy rate was significantly improved.
