P-506 Reflecting on the Importance of Family Building and Fertility Preservation: Transgender People’s Experiences with Starting Gender-affirming Treatment as Adolescent

Abstract

Abstract Study question To investigate how adults of reproductive age (± 30 years), who started gender-affirming treatment during adolescence, reflect on their reproductive wishes. Summary answer Views regarding fertility and family building change over time, which may be related with reduced levels of gender dysphoria, matured intellectual and emotional cognitions. What is known already Within the last two decades, gender-affirming care for transgender youth has become widely available. One of the topical debates in adolescent transgender care concerns the difficulty of making decisions regarding fertility at an early age, since medical treatment for gender dysphoria negatively affects reproductive function. In transgender adolescents, data on the potential change in wishes and desires regarding fertility, family building and the importance of biological parenthood, when coming of reproductive age, are lacking. Hereby, the long-term consequences of acquired infertility in transgender adolescents who have now reached adulthood remain still unknown. Study design, size, duration This was a questionnaire study. Gender diverse adolescents who presented between 1989 and 2000 and started medical transition, were recruited for participation. As well as gender diverse adolescents who commenced medical treatment with gonadotropin-releasing hormone agonist (GnRHa) prior to gender affirming hormone treatment (GAHT), at least 9 years ago. 89 participants were eligible for inclusion in the study cohort. Participants/materials, setting, methods Data were collected through an online survey, and a subsequent telephonic interview to validate the provided answers in the survey. The fertility questionnaire focused on different themes, such as fertility counseling at initiation of medical treatment, decision-making about fertility preservation, current feelings about infertility, and a potential desire to have children. Main results and the role of chance The cohort consisted of 89 participants, among whom 66 trans masculine and 23 trans feminine people. Participants had a mean age of 32.4 years (SD 6.6, range 25.5-51.2) at time of the study, and 15.6 years (SD 2.2, range 11.5-20.6) at time of start of medical treatment. Since all participants initiated medical treatment before 2014, at that time laws requiring sterilization for legal gender recognition were still in place. Only 30% of participants received information about the options for fertility preservation, and none of them pursued fertility preservation. In addition, 96% of participants underwent gonadectomy and thus became permanently infertile. 27% of participants found becoming infertile troublesome, and 21% stated that they were not able to make decisions regarding fertility and future family building during adolescence. With today’s knowledge, 14% of trans masculine and 17% of trans feminine people would not have chosen to undergo gonadectomy. In addition, 44% of trans masculine and 35% of trans feminine people would pursue fertility preservation. The percentage of participants with a (future) desire for children changed from 34% at start of medical treatment to 56% at time of this study, of whom 23% had already started a family. Limitations, reasons for caution Since the participants reflect on a period in time in which fertility counseling was not offered on a structural basis and preservation options were not widely available, results of this study may not be fully translatable to current practice. Wider implications of the findings Transgender adolescents should be counselled on fertility and the options for fertility preservation, even in the absence of a desire for children upon initiation of treatment. Views on future family building might change over time, fertility counseling should be repeated at each step of the transition. Trial registration number na
