摘要
目的探讨不同阴道给药黄体支持方案对激素替代治疗(HRT)周期冻融胚胎移植(FET)患者妊娠结局的影响。方法回顾性分析2011年1月至2017年12月在我院生殖中心接受HRT-FET的5 011个周期的临床资料,根据不同的用药情况将纳入对象分为2组:黄体酮阴道缓释凝胶联合地屈孕酮片组(A组,3 049个周期),黄体酮软胶囊联合地屈孕酮片组(B组,1 962个周期)。比较两组患者的基本情况及临床结局。结果两组患者的年龄、体重指数(BMI)、孕酮转化日子宫内膜厚度等基本情况比较,差异均无统计学意义(P>0.05)。A组的胚胎着床率显著高于B组(49.89%vs.47.20%),早期流产率则显著低于B组(7.93%vs.10.49%),差异均有统计学意义(P<0.05);两组的生化妊娠率、临床妊娠率、宫外孕率及多胎率比较,差异均无统计学意义(P>0.05)。结论黄体酮阴道缓释凝胶联合地屈孕酮片和黄体酮软胶囊联合地屈孕酮片两种黄体支持方案应用于HRT-FET患者可以取得相似的临床结局,使用黄体酮阴道缓释凝胶联合地屈孕酮片可以提高胚胎着床率,降低早期流产率。
Objective:To investigate the effect of different vaginal corpus luteum support regimen on pregnancy outcome in hormone replacement therapy(HRT)&frozen-thawed embryo transfer(FET)cycle.Methods:The clinical data of 5 011 HRT-FET cycles in our clinic center from January 2011 to December 2017 were retrospectively analyzed.The cycles were divided into two groups:the patients received a combination of progesterone vaginal sustained-release gel and dydrogesterone in group A(3 049 cycles);the patients received a combination of progesterone soft capsule and dydrogesterone in group B(1 962 cycles).The basic condition and clinical outcomes were compared between the two groups.Results:There were no significant differences in age,BMI and endometrial thickness on progesterone conversion day,etc.between the two groups(P >0.05).The implantation rate in group A were significantly higher than that in group B(49.89% vs.47.20%)(P<0.05),and the early abortion rate in group A were significantly lower than that in group B(7.93% vs.10.49%)(P<0.05).There were no significant differences in the biochemical pregnancy rate,clinical pregnancy rate and ectopic pregnancy rate between the two groups(P>0.05).Conclusions:In the HRT-FET cycles,the similar clinical outcomes can be obtained when the combination of progesterone vaginal sustained-release gel and dydrogesterone or the combination of progesterone soft capsule and dydrogesterone were used for corpus luteum support.However the combination of progesterone vaginal sustained-release gel and dydrogesterone can increase implantation rate and reduce early abortion rate.
