Oocyte Cryopreservation in Transgender and Gender-Diverse Individuals With or Without Prior Testosterone Use.

To evaluate oocyte cryopreservation among transgender and gender-diverse adolescents and young adults with or without prior testosterone exposure, we performed a retrospective cohort study of all patients younger than age 35 years referred for oocyte cryopreservation through our formal fertility-preservation program from 2014 to 2023. The number of patients referred and pursuing fertility preservation increased over time. Among the 93 patients referred, 37 pursued oocyte cryopreservation (31 testosterone-naïve and six testosterone-exposed). Among the latter, neither length of time on testosterone before presentation nor duration off testosterone before retrieval (minimum 2 months) were associated with the number of mature oocytes frozen. When comparing testosterone-naïve with testosterone-exposed individuals, there was no difference in number of oocytes retrieved (median 28 vs 32, P=0.43) or mature oocytes frozen (21 vs 21, P=0.95).
