两种黄体酮阴道用药方案在胚胎植入前经遗传学检测的冻融胚胎移植中的临床效果

目的 比较黄体酮阴道缓释凝胶联合地屈孕酮和黄体酮软胶囊联合地屈孕酮作为胚胎植入前遗传学检测（PGT）冻融胚胎移植后黄体支持的效果。方法 选择2017年6月~2020年6月在我院接受PGT助孕的209例患者，根据在激素替代冻融胚胎移植周期中阴道黄体支持用药的不同将患者分为2组：黄体酮阴道缓释凝胶（雪诺同）+地屈孕酮组（n=135）和黄体酮软胶囊（安琪坦）+地屈孕酮组（n=74），比较两种联合用药方案的临床应用效果及妊娠结局。结果 两组的年龄、不孕年限、抗苗勒氏激素、基础窦卵泡数、BMI、基础FSH、基础LH、基础E2差异无统计学意义（P>0.05）；两组Gn启动剂量、Gn时间、Gn总剂量、hCG日LH、 E2、P及内膜厚度、获卵数、MII卵子数、受精数及可移植囊胚数差异无统计学意义（P>0.05）；两组冻胚移植周期内膜准备时间、内膜转化日P和内膜厚度、生化妊娠率（69.63% vs 78.38%）、临床妊娠率（62.96% vs 72.97%）、流产率（12.94% vs 11.11%）、早孕阴道出血率（20% vs 27.78%）及阴道出血者的流产率（35.29% vs 20%）的差异无统计学意义（P>0.05）。结论 黄体酮阴道缓释凝胶联合地屈孕酮和黄体酮软胶囊联合地屈孕酮作为PGT冻融胚胎移植后黄体支持可获得相似的临床效果。

Efficacy of vaginal administration of Crinone versus Utrogestan combined with oral dydrogesterone tablets for luteal support in PGT freeze-thaw embryo transfer cycles

Objective To compare the efficacy of two vaginal progesterone formulations, Crinone gel or Utrogestan capsules, combined with dydrogesterone tablets, for luteal phase support in pre-implantation genetic testing (PGT) freeze-thaw embryo transfer (FET) cycles. Methods We analyzed 209 FET cycles in patients undergoing PGT-blastocyst transfer in our center between June, 2017 and June, 2020. The patients received vaginal administration of either Crinone gel (n=135) or Utrogestan capsules (n=74) combined with oral dydrogesterone tablets for luteal supplementation, and the clinical pregnancy rate (CPR) and miscarriage rate (MR) were compared between the two groups. Results The Crinone gel and Utrogestan capsule groups were comparable for age, duration of infertility, AMH, AFC, BMI, basal FSH, LH, and E2 (P>0.05). The gonadotrophin dose, duration of stimulation, levels of LH, E2, P and endometrial thickness on hCG day, and the numbers of oocytes retrieved, MII oocytes, 2PN and blastocysts did not differ significantly between two groups (P>0.05). In FET cycles, no significant differences were observed between the two groups in the duration of endometrial preparation, P and endometrial thickness on endometrial transformation day, biochemical pregnancy rate (69.63% vs 78.38% ), CPR (62.96% vs 72.97% ), MR (12.94% vs 11.11%), vaginal bleeding rate in early pregnancy (20% vs 27.78%), or MR in patients with vaginal bleeding in early pregnancy (35.29% vs 20% ) (P>0.05). Conclusion Crinone gel and Utrogestan capsules combined with oral dydrogesterone have similar clinical efficacy for luteal support in PGT FET cycles.
