卵母细胞体外成熟(IVM)是一项新的辅助生殖技术。而卵母细胞IVM后妊娠率很低。本研究旨在评估联合应用FSH和hCG是否会影响IVM中卵母细胞的数量及体外成熟的潜力、子宫内膜的厚度和妊娠率。方法采集1999年11月～2000年12月共60例多囊卵巢综合征(PCOS)接受IVM周期的妇女。所有月 Oocyte in vitro maturation (IVM) is a new assisted reproductive technology. The pregnancy rate of IVM after oocytes is very low. The aim of this study was to evaluate whether the combination of FSH and hCG affects the number of IVM oocytes and the potential for in vitro maturation, the thickness of the endometrium and the pregnancy rate. Methods A total of 60 women with polycystic ovary syndrome (PCOS) undergoing IVM cycles from November 1999 to December 2000 were enrolled. All month
