不同辅助生殖技术助孕后新生儿性别比例分析

摘要

Objectives:To analysis the effect of assisted reproductive technology on newborn sex ratio.Methods:Retrospective analysis on 495 newborns by assisted reproductive technology at the Center for Reproductive Medicine of Anhui Maternal and Children Health Care Hospital from January 2014 to January 2016 was done.The sex ratio was analyzed according to different type of cycle and stage of embryo transferred.Results:The newborns included 253 male and 242 female babies.The male ratio of frozen-thawed embryo transfer cycle was higher than that of fresh embryo transfer cycle (52.45％ VS 48.52％,P =0.406) and male ratio of blastophere was higher than that of cleavage stage embryo (56.69％ VS 48.52％,P =0.091),but there was no difference (P ＞ 0.05).Conclusion:Different methods of assisted reproductive technology do not affect the newborn sex ratio.%目的:分析辅助生殖技术对新生儿性别比例的影响.方法:回顾性分析2014年1月至2016年1月在我院生殖医学中心经辅助生殖技术助孕新生儿总数495人,根据周期类型和移植胚胎发育阶段分别两两比较新生儿性别比例.结果:所有新生儿中男性253人,女性242人,新生儿中男性比例复苏周期高于新鲜周期(52.45％ vs.48.52％,P=0.406),囊胚高于卵裂期胚胎(56.69％ vs.48.52％,P=0.091),但均无统计学差异.结论:不同辅助生殖技术方法不影响新生儿性别比例.
