Effectiveness and Safety Study of Fixed Versus Flexible of Gonadotropin-releasing Hormone Antagonist Protocol

Summary

The purpose of study is to compare the effectiveness of the Day-5 fixed administration of GnRH antagonist versus flexible administration of GnRH antagonist during ovarian stimulation in Chinese women with predicted high ovarian response, and the hypotheses is that the number of oocyte retrieved in fixed protocol is not inferior to GnRH antagonist flexible protocol.
