Use of Fertility Preservation Among a Cohort of Transgirls in the Netherlands

Abstract Purpose The primary aims of the study are to examine the rate of attempted fertility preservation (FP) among a Dutch cohort of transgirls who started gonadotropin-releasing hormone analog treatment and the reasons why adolescents did or did not choose to attempt FP. Methods The study was a single-center retrospective review of medical records of 35 transgirls who started gonadotropin-releasing hormone analog treatment between 2011 and 2017. Results Ninety-one percent of adolescents were counseled on the option of FP. Thirty-eight percent of counseled adolescents attempted FP, and 75% of them were able to cryopreserve sperm suitable for intrauterine insemination or intracytoplasmic sperm injection. Younger and Caucasian transgirls were less likely to attempt FP. No specific reason for declining FP was known in 33% adolescents, 32% of adolescents were not able to produce a semen sample because of early puberty, 17% felt uncomfortable with masturbation, 17% did not want to have children, and 13% wanted to adopt. Conclusions One third of adolescents attempted FP, which is much more than the percentage reported in previous studies from the United States. One third of the transgirls could not make use of FP because they were unable to produce a semen sample because of early pubertal stage. For these adolescents, alternatives need to be explored.
