目的:控制性促排卵(COS)结合宫内受精(IUI)普遍用于治疗不明原因性不孕症。其与单纯的COS或IUI相比,可以显著提高累计妊娠率,但同时却增加了卵巢过度刺激综合征(OHSS)及多胎妊娠的发生率。本研究评价了前4个COS-IUI治疗周期卵泡的数目对继续妊娠率和多胎妊娠率的影响。材料方法
OBJECTIVE: Controlled ovulation induction (COS) combined with intrauterine fertilization (IUI) is commonly used to treat unexplained infertility. Compared with simple COS or IUI, it can significantly increase the cumulative pregnancy rate, but at the same time it increases the incidence of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancy. This study evaluated the effect of the number of follicles treated with the first four COS-IUI cycles on continued pregnancy and multiple pregnancy rates. Material method
