Fertility preservation in cancer patients: Data collection, analysis, and continuous improvement of cryostorage.

Data collection from all referred patients allows continuous learning and improvement of services. Patient safety and return for cancer therapy takes priority in all oncofertility services. In certain cases, the intervention for female patients is contraindicated and, aside from extensive counseling, alternative methods of preserving fertility should be explored. Long-term follow-up of these patients provides answers to many questions that remain unanswered to date. An annual audit should be performed and contact with the oncology services and with patients that attended for cryopreservation must be routine.
