[Fertility preservation for transmen]

The evolution of medical techniques as well as legislative changes currently allow to propose fertility preservation strategies in the context of transidentity. During "female to male" transition, androgen therapy has an impact on gonadal function since it usually induces a blockage of ovulation with amenorrhea. Although this effect is reversible when treatment is stopped, the possible long-term effects of testosterone treatment on future fertility or health of future children are poorly known. In addition, transitional surgeries definitely compromise fecundity when they include bilateral ovariectomy and/or hysterectomy. Yet, although long ignored or poorly expressed, the desire for parenthood is a reality in transgender men. Fertility preservation options in FtM transition rely on oocyte or ovarian tissue cryopreservation. The purpose of this review is to provide an overview of the literature regarding fertility preservation in transgender men. Although series remain limited, the increase in the number of recently published articles reflects the interest in improving the management of fertility issues in transgender men.
