Fifteen Year Regional Center Experience in Sperm Banking for Cancer Patients: Use and Reproductive Outcomes in Survivors

摘要

Sperm cryopreservation before gonadotoxic iatrogenic treatments is the only method currently available to preserve fertility in men with cancer. The aims of this study were to report our 15 years of experience, the clinical outcomes of assisted reproductive treatments as well as neonatal characteristics of babies born. We retrospectively reviewed 682 oncological patients who were referred to our center from 2004 to 2019 for fertility preservation. Data regarding cancer diagnosis, age, and the use of frozen semen were analyzed. The cumulative live-birth delivery rate per couple was 35%. No stillbirths, as well as no malformations in the babies born, were recorded. These successful findings demonstrated that pregnancy could be safely achieved using frozen-thawed sperm of cancer survivors who cryopreserved before gonadotoxic therapies.
