Brief Summary

Oocyte vitrification after in vitro maturation (IVM) is one of the main techniques for preserving female fertility before chemotherapy for breast cancer. In this technique, originally developed for patients with ovarian pathology, polycystic ovarian syndrome, induction of an LH peak has been shown to improve outcomes. Young women with breast cancer, who are candidates for urgent fertility preservation, do not have ovarian pathology. The objective of the present study is to assess whether the absence of therapeutic intervention prior to oocyte retrieval for IVM in these patients is at least as effective as the injection of hCG or GnRH agonist used in routine practice.
