研究目的:

探究采用改良拮抗剂方案进行IVF促排卵的卵巢正常反应人群中,地塞米松是否能降低扳机日血清孕酮水平,从而改善新鲜周期单胚胎移植妊娠结局。  

Objectives of Study:

To investigate whether dexamethasone can reduce serum progesterone levels on HCG day and thereby improve live birth rates per fresh embryo transfer cycle in normal responders undergoing modified flexible GnRH antagonist protocol.
