目的 通过监测供精人工授精技术(artificial insemination by donor,AID)助孕后妊娠患者,了解其子代出生缺陷和遗传代谢病情况,为建立规范的监测子代出生缺陷的机制提供理论依据。方法 随访供精人工授精技术助孕后妊娠分娩的患者,收集其子代临床资料,部分新生儿采集足跟血制成滤纸干血斑标本,进行串联质谱分析,筛查遗传代谢病,可疑对象进行重复检测和专科咨询检查。结果 收集分析2007年—2016年通过AID出生的4 261例子代临床资料,360例新生儿采集足跟血进行 50种遗传代谢病检测。子代出生缺陷率1.24%(不包括230例轻度地方病地中海贫血症、24例G6PD缺乏症和两病共患5例),360例中未发现重度地中海贫血症、先天性甲状腺低下症、苯丙酮尿症等其他遗传代谢病。本中心建立宣传教育新生儿遗传代谢病筛查和转诊制度。结论 供精人工授精技术助孕后妊娠出生的子代出生缺陷和遗传代谢病发病率低,冻存精子进行供精人工授精助孕,是一种较安全获得健康子代的辅助生殖技术。

目的 探讨影响自然周期供精人工授精妊娠的因素。方法 回顾性分析2007年4月—2013年4月期间在广东省计划生育专科医院行自然周期供精人工授精的6161个周期,其中妊娠组1454周期,对照组4707个周期。采用单因素分析及多因素Logistic回归分析女方年龄、不孕年限、子宫内膜厚度、类型及冻融复苏后前向运动精子总数与AID妊娠结局的关系。结果 年龄越大,不孕年限越长,妊娠率越低(P＜0.001); A型子宫内膜妊娠率25.94%较AB型的23.87%及B型的21.54%都高(P=0.001);妊娠组冻融复苏后前向运动精子总数均值(28.95±6.86)×10⁶较对照组的(28.26±6.98)×10⁶高(P=0.001);年龄(OR=1.614,P＜0.001)、不孕年限(OR=1.194,P=0.012)、子宫内膜分型(OR=1.258,P=0.001)影响妊娠率。结论 女方年龄、不孕年限、子宫内膜形态及冻融复苏后前向运动精子总数是影响自然周期供精人工授精妊娠的因素。

Objective To explore the parameters affecting the pregnancy rate from 6161 natural cycles of artificial insemination by donor(AID). Methods Consecutive cases of 6161 natural cycles of AID from April,2009 to April 2013 in Guangdong provincial family planning special hospital were analyzed retrospectively.1454 pregnant cycles were defined as observation group and the other 4707 non pregnant cycles were classified as control group.Related factors in effect of pregnancy rate of AID were analyzed by logistic regression analysis. Results The rate of pregnancy decreased with the increase of women ages and the infertility duration(P＜0.001).And the pregnancy rate of ICI among the women with type A endometrium was the highest among the three types of endometrium(25.94%vs23.87%vs21.54%,P=0.001).The sum of the forward moving sperm after freezing and thawing recovery of observation group is higher than control group(28.95±6.86)×10⁶vs (28.26±6.98)×10⁶.The value of OR of age,infertility duration and types of endometrium were 1.614,1.194 and 1.258,respectively. Conclusion Age of women,infertility duration,types of endometrium as well as the sum of the forward moving sperm after freezing and thawing recovery played an important role in pregnancy rate of natural cycles of AID.
