To study the impact of stimulation duration on intracytoplasmic sperm injection (ICSI) - embryo transfer (ET) outcome in poor and normal responders during controlled ovarian stimulation using gonadotropin-releasing hormone (GnRH) antagonist protocol.
This is a retrospective cohort study. There were 1481 women undergoing ICSI-ET cycles. Women with ovum pick-up number ≤3 were defined as poor responders (n = 235), and those with a number ≥4 were normal responders (n = 1246).
The mean stimulation duration was shorter in poor responders with pregnancy group as compared with normal responders with pregnancy group (7.8 ± 2.2 vs. 9.2 ± 1.6 days, p < 0.01). Poor responders with a shortest stimulation duration (≤6 days) appeared a higher live birth rate (≤6 days: 33.3%, 7-8 days: 20.0%, 9-10 days: 15.9%, and ≥11 days: 11.1%, p = 0.18). Normal responders with a shortest stimulation duration (≤6 days) appeared a lowest live birth rate (≤6 days: 28.6%, 7-8 days: 35.8%, 9-10 days: 33.6%, and ≥11 days: 29.3%, p = 0.61). Oocyte maturation rate was significantly lower at stimulation durations ≤6 days group (≤6 days: 67%, 7-8 days: 80%, 9-10 days: 85%, and ≥11 days: 87%, p = 0.02) in normal responders.
In ICSI-ET cycles, stimulation duration appears to have different impact on oocyte maturation, clinical pregnancy rates and live birth rates in both poor and normal responders.
研究在使用促性腺激素释放激素(GnRH)拮抗剂方案进行控制性卵巢刺激时,刺激持续时间对卵胞浆内单精子注射(ICSI)-胚胎移植(ET)结局的影响,分别在卵巢反应不良和正常的患者中进行研究。
这是一项回顾性队列研究。共纳入 1481 例接受 ICSI-ET 周期的患者。取卵数≤3 定义为卵巢反应不良(n=235),取卵数≥4 定义为卵巢反应正常(n=1246)。
与妊娠组的正常反应者相比,妊娠组的卵巢反应不良者的平均刺激持续时间更短(7.8±2.2 天 vs. 9.2±1.6 天,p<0.01)。刺激持续时间最短(≤6 天)的卵巢反应不良者的活产率更高(≤6 天:33.3%,7-8 天:20.0%,9-10 天:15.9%,≥11 天:11.1%,p=0.18)。刺激持续时间最短(≤6 天)的正常反应者的活产率最低(≤6 天:28.6%,7-8 天:35.8%,9-10 天:33.6%,≥11 天:29.3%,p=0.61)。正常反应者中,刺激持续时间≤6 天组的卵母细胞成熟率显著降低(≤6 天:67%,7-8 天:80%,9-10 天:85%,≥11 天:87%,p=0.02)。
在 ICSI-ET 周期中,刺激持续时间对卵巢反应不良和正常患者的卵母细胞成熟率、临床妊娠率和活产率均有不同的影响。
