Study summary

The aim of this study is to analyze the effectiveness of GnRh antagonist in the treatment of early ovarian hyperstimulation syndrome.

Read the detailed description

Ovarian hyperstimulation syndrome (OHSS) is a serious complication of ovarian stimulation protocols. Gonadotrophin-releasing hormone (GnRH) antagonist administration in the luteal phase was recently proposed as a new approach for the management of patients with established severe OHSS We analyze the response of egg donors with moderate- severe early ovarian hyperstimulation syndrome after a GnRH antagonist stimulation protocol to the administration of a daily doses of GnRH antagonist (Cetrorelix 0.25) during 7 days after the second day of oocyte retrieval compared with placebo (saline solution).
