Cryopreservation of Ovarian Cortex in Girls With Turner Syndrome

Ovarian insufficiency is common in Turner syndrome related to premature and rapid follicular apoptosis and spontaneous pregnancies are rare in this population. Ovarian cryopreservation has been used in an effort to preserve fertility in patients undergoing treatments which lead to premature and severe ovarian insufficiency. This study aims to assess the relevance of ovarian tissue cryopreservation in girls with Turner syndrome. Based on ovarian follicular density as primary outcome and karyotypic, clinical and hormonal markers as secondary outcomes, analysis of the study will allow to select the patients to whom the procedure would benefit the most.
