Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the efficacy of the weekly use of corifollitropin alfa in double ovarian stimulation process and to compare it to the conventional protocol with daily medication administration.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this pilot study is to evaluate the efficacy of the weekly use of corifollitropin alfa in terms of ovarian stimulation results and its biological outcomes (total number of oocytes retrieved) in case of ovarian stimulation cycles in double stimulation modality (DUOSTIM) and in comparison with the conventional DUOSTIM protocol: daily administration of gonadotropins.
