IVF-ET促排卵方案在多囊卵巢综合征患者中的应用进展

多囊卵巢综合征(PCOS)患者的亚生育状态困扰着许多夫妇，随着辅助生殖技术的不断发展，越来越多的PCOS不孕患者选择接受体外受精-胚胎移植（IVF-ET）助孕。IVF-ET作为一种不孕症的治疗方式，为PCOS患者带来了希望，但PCOS患者病情复杂、多样，促使卵泡发育的促性腺激素（Gn）剂量和导致卵巢过度刺激（OHSS）发生的剂量非常接近，使得临床工作极富挑战。因此，临床上治疗PCOS不孕症患者需要选择一种合适的促排卵方案，以获得高的妊娠率和低并发症发生率。促排卵方案各有其优缺点，目前没有哪一种方案能够推广成为公认最适宜PCOS患者的促排卵方案。本文综述了较适宜的五种促排方案的优缺点，以期指导临床。
