The present protocol describes a method for assessing ovarian reserve in patients under 25 years old who require fertility preservation through ovarian tissue cryopreservation. This method involves: (1) histological assessment of ovarian reserve in cortical samples, (2) comparison to a reference dataset, and (3) calculation of Z-scores.
