Summary

The present investigation aims to evaluate the efficacy of an innovative protocol of controlled ovarian stimulation for breast cancer patients, who are candidates for fertility preservation.

Currently, vitrification of oocytes and/or embryos after controlled ovarian stimulation is the most established method for female fertility preservation. However, this stimulation induces an increase in serum estrogen levels, which is theoretically problematic in case of hormone-sensitive tumors such as breast cancer. The majority of oncology teams accept, in very specific situations (particularly when the tumor has been surgically removed), this ovarian stimulation, because the expected benefits of fertility preservation far outweigh the risks. However, everyone agrees that it would be more comfortable to be able to offer vitrification of oocytes and/or embryos using ovarian stimulation without increasing estrogen levels.

In this research, investigators will evaluate the efficacy of degarelix (Firmagon®), currently indicated for the treatment of prostate cancer, as an innovative ovarian stimulation procedure. Administered at the beginning of ovarian stimulation, they believe it should maintain serum estradiol levels at physiological values at the end of stimulation.
