Abstract
Preserving female fertility is crucial in a multifunctional healthcare system that takes care of patients’ future quality of life. Oocyte cryopreservation is recognized by several international scientific societies as the gold standard for fertility preservation in postpubertal women, for both medical and non-medical indications. The main medical indications are oncologic diseases, gynecologic diseases such as severe endometriosis, systemic diseases compromising the ovarian reserve, and genetic conditions involving premature menopause. This paper describes the whole clinical and laboratory work-up of a fertility preservation treatment by outlining recommendations for objective and evidence-based counseling. Furthermore, it focuses on the effectiveness of the procedure and describes the most appropriate strategies to fully exploit the ovarian reserve and maximize the number of oocytes retrieved in the shortest possible time. The evaluation of the ovarian reserve, the definition of an ideal stimulation protocol, as well as oocyte retrieval, denudation, and vitrification procedures have been detailed along with approaches to maximize their efficacy, efficiency, and safety.
