摘要:

目的:研究降调节激素替代方案中雌激素启动时机对冻融胚胎移植(frozen-thawed embryo transfer,FET)妊娠结局的影响。方法:对采用降调节激素替代方案行FET的436个周期进行研究。雌激素启动前持续监测血清雌二醇(estradiol,E2)水平,根据E2处于上升或下降趋势分为2组。A组雌激素类药物使用前E2呈上升趋势,共262个周期;B组雌激素类药物使用前E2呈下降趋势,共174个周期。比较2组患者的一般情况、降调节后的临床指标及妊娠结局。结果:2组患者的年龄、体质量指数(BMI)、不孕年限、基础性激素水平等基本情况差异无统计学意义(均P>0.05)。A组使用雌激素时间及雌激素用量低于B组,差异有统计学意义(P<0.05)。A组早期流产率低于B组,差异有统计学意义(P<0.05)。结论:FET周期中,注射长效促性腺激素释放激素激动剂(gonadotropin- releasing hormone agonist,GnRHa)降调节后,待血清雌激素水平呈上升趋势时启动,可以缩短外源性雌激素用药时间,节省外源性雌激素用量,有利于降低早期流产率,改善妊娠结局。

Abstract:

Objective: To study the effect of estrogen starting time on the outcome of frozen-thawed embryo transfer (FET) in hormone replacement treatment (HRT) after GnRHa down regulation. Methods: The 436 cycles of FET with GnRHa down regulation + HRT protocol were studied retrospectively. According to the rising or falling trend of serum estrogen level (E2) before the start of estrogen, these cycles were divided into two groups. Group A: E2 showed an upward trend before estrogen starting, 262 cycles; Group B, E2 showed a downward trend before estrogen starting, 174 cycles. The baseline characteristics, clinical indicators after down regulation and pregnancy outcome between the two groups were compared. Results: There were no statistically significant differences in baseline characteristics such as age, body mass index (BMI), years of infertility, and baseline of serum hormone between the two groups (P>0.05). The average days of estrogen use and the amount of estrogen in the group A were significantly lower than those in the group B (both P<0.05). The early miscarriage rate in the group A was lower than that in the group B (P<0.05). Conclusions: During the GnRHa down regulation + HRT cycles, estrogen starting when the level of serum estrogen shows an upward trend can shorten the using days of exogenous estrogen, save the amount of exogenous estrogen, decrease early miscarriage, and improve the pregnancy outcome in the end.
