NEJM:胚胎移植方式对非多囊卵巢综合征不孕女性活产率影响研究

2018-01-11 zhangfan MedSci原创

研究发现,非多囊卵巢综合征不孕女性,胚胎移植方式对于持续妊娠以及活产率的影响不显著

对于接受体外受精(IVF)的多囊卵巢综合征不孕女性,冷冻胚胎移植的活产率高于新鲜胚胎移植,但其对于与多囊卵巢综合征无关不孕症女性的影响尚不清楚。

研究招募了782名无多囊卵巢综合征的不孕女性,接受冷冻或新鲜胚胎移植。对于冷冻移植组,所有1-2级胚胎均已进行冷冻保存,并在下一周期的移植日,最多解冻两个胚胎。对于新鲜移植组,在刺激周期内,最多移植2枚新鲜胚胎。研究的主要终点是移植后持续妊娠率。

第一个移植周期后,冷冻胚胎组391名患者中142人实现持续妊娠(36.3%),而新鲜胚胎组391人,135人实现持续妊娠(rr,1.05,95%,CI,0.87-1.27)。首次移植后的活产率分别为33.8%vs31.5%(rr, 1.07;95% CI,0.88-1.31)。

研究发现,非多囊卵巢综合征不孕女性,胚胎移植方式对于持续妊娠以及活产率的影响不显著。

人类体外受精-胚胎移植实验室操作专家共识(2016)

体外受精-胚胎移植(IVF-ET)技术已在我国大陆地区发展27年,近15年来,该项技术迅速成长,大批生殖中心在各地陆续建成。2001~2003年,卫生部主管部门颁布了一系列针对辅助生育技术的技术规范及管理办法,使得该项技术走向规范化,得到健康发展。2005年12月,中华医学会生殖医学分会(CSRM)成立,进一步促进了该学科的学术发展。近些年来,中华医学会生殖医学分会各方面专家在临床、实验室方面均积
