Introduction: Ovarian tissue cryopreservation (OTC) is recommended by scientific societies for women undergoing highly gonadotoxic cancer treatments. Following transplantation, the restoration of ovarian function is typically characterised by the resumption of spontaneous menstruation. Yet, a few studies have looked at the longitudinal hormonal variations following transplantation.

Letrozole-associated controlled ovarian hyperstimulation (LetCOH) is used worldwide to collect mature oocytes for FP, but its efficacy and safety compared to conventional protocols (cCOH) are still debated.
Aims: To compare efficacy and safety of FP procedure using LetCOH or cCOH in BC patients in terms of oocyte maturation rate and disease-free survival rates after at least two years of follow-up.
The relationship between early recovery of menstrual activity and blood anti-Müllerian hormone (AMH) concentrations were investigated within the first year post-chemotherapy in 32 young patients with breast cancer. All were treated by surgery and the same chemotherapy protocol (three cycles of FEC100 plus three cycles of taxanes). Menstrual activity, blood AMH (using picoAMH ELISA) and FSH concentrations were measured longitudinally before, during and up to 12 months after the end of chemotherapy (six samples per patient).
