摘要

目的

探讨拮抗剂固定方案中GnRH拮抗剂使用时间对非多囊卵巢综合征（PCOS）患者鲜胚移植周期临床结局的影响

。

方法

回顾性分析于我院生殖医学中心行体外受精/卵胞浆内单精子注射（IVF/ICSI）治疗的279例不孕患者的临床资料。按照促排卵过程中GnRH拮抗剂使用时间，将患者分为拮抗剂使用时间≤3 d组和拮抗剂使用时间

3 d组。比较2组患者的基本临床特征、促排卵周期特征和鲜胚移植周期妊娠结局的差异。单因素和多因素

回归分析鲜胚移植周期妊娠结局的影响因素。

结果

拮抗剂使用时间≤3 d组获卵率和周期取消率低于拮抗剂使用时间

3 d组（

3 d组（

0.05）。2组间优胚率、第二次减数分裂中期（MⅡ）卵率、正常受精率、持续妊娠率、活产率、早期流产率差异无统计学意义(

Abstract

Objective

To investigate the effect of GnRH antagonist administration duration in the antagonist fixation protocol on the clinical outcomes of fresh embryo transfer cycle in patients with non-polycystic ovary syndrome （PCOS）.

Methods

The clinical data of 279 infertile patients who underwent in vitro fertilization/intracytoplasmic sperm injection （IVF/ICSI） in Reproductive Medicine Center of our hospital were retrospectively analyzed. According to the GnRH antagonist administration duration during ovulation induction，they were divided into the antagonist administration duration≤3 days group and the antagonist administration duration

3 days group. The basic clinical characteristics， ovulation induction cycle characteristics and pregnancy outcomes of fresh embryo transfer cycle were compared between the two groups. Univariate and multivariate

Logistic

regression analysis were used to analyze the factors influencing the pregnancy outcomes of fresh embryo transfer cycle.

Results

The oocytes retrieved rate and the cycle cancellation rate in the antagonist administration duration≤ 3 days group were significantly lower than those in the antagonist administration duration

3 days group （

0.05）， and the implantation rate and clinical pregnancy rate were significantly higher than those in the antagonist administration duration

3 days group （

0.05）. There was no statistically significant difference in the optimal embryo rate，metaphase Ⅱ（MⅡ） oocytes rate， normal fertilization rate， persistent pregnancy rate， live birth rate and early abortion rate between the two groups （

0.05）. Univariate regression analysis showed that the antagonist administration duration

3 days was associated with the decrease of the implantation rate ［

=0.020］ and the clinical pregnancy rate ［

（95%

）： 0.400（0.191 to 0.840），

=0.015］， but had no effect on persistent pregnancy rate， live birth rate and early abortion rate. Multivariate

Logistic

analysis showed that after adjusting for confounding variables， antagonist administration duration

3 days was still an important factor in reducing the clinical pregnancy rate ［

）： 0.408（0.188 to 0.888），

Conclusion

In the antagonist fixation protocol for non-PCOS patients， the antagonist administration duration>3 days is associated with the decrease of embryo implantation rate and clinical pregnancy rate in the fresh embryo transfer cycle.
