目的:报道3例多囊卵巢综合征(PCOS)患者实施IVF-ET技术采用黄体期促排卵方案的病案。方法:对3例PCOS患者接受常规促排卵方案单一卵泡发育或提前排卵后继续行黄体期促排卵进行回顾性总结与分析。结果:采用微刺激、拮抗剂方案控制性超促排卵(COH),单一卵泡发育或提前排卵后,补救性联合黄体期促排卵可提高获卵数,增加优质胚胎数,降低卵巢过度刺激综合征(OHSS)的发生率。结论:对于常规方案促排卵单卵泡发育或提前排卵后的PCOS患者,继续黄体期促排卵可能成为一种新的有效促排卵方案。 OBJECTIVE: To report the case of IVF-ET technique in ovariectomized ovariectomized women in 3 patients with PCOS. Methods: Three cases of PCOS patients receiving routine ovulation induction single ovarian follicular development or ovulation in advance after luteal phase ovulation induction were retrospectively summarized and analyzed. Results: Ovariectomy combined with micro-stimulation and antagonist regimen controlled ovarian hyperstimulation (COH), single follicle development or early ovulation induction could increase the number of oocytes retrieved, increase the number of high-quality embryos and reduce ovarian hyperstimulation syndrome (OHSS) incidence. CONCLUSIONS: Continuing luteal phase ovulation induction may be a new and effective strategy for ovulation induction in patients with PCOS after ovulation induction or single ovulation in conventional regimen.
