Abstract

Purpose: To investigate if the combination of clomiphene citrate, hMG, and cetrorelix (CC/hMG/cetrorelix protocol) can be applied to patients who had excessive response to GnRHa long protocol. Methods: Fifty patients who coasted and failed to conceive in their first cycles stimulated with GnRHa long protocol were stimulated with CC/hMG/cetrorelix protocol. The peak serum estradiol levels, the need of coasting and prolonged coasting (≥4 days), and the incidences of OHSS were compared. Results: The peak estradiol level was significantly lower with CC/hMG/cetrorelix protocol compared to GnRHa long protocol. With CC/hMG/cetrorelix protocol, only four patients (8%) needed coasting and no one coasted ≥4 days. In contrast, in the first cycles, 11 patients (22%) needed coasting ≥4 days. The incidence of moderate OHSS was significantly lower with CC/hMG/cetrorelix protocol. Conclusions: The CC/hMG/cetrorelix protocol is an acceptable alternative protocol for patients who had excessive response to GnRHa long protocol.
