For individuals pursuing medically assisted gender transition, gender-affirming surgical treatments, such as oophorectomy (removal of the ovaries) and orchiectomy (removal of the testicles), cause sterility, and gender-affirming hormone treatment with medications (i.e., testosterone and estrogen) may negatively impact infertility. The major United States (US) medical associations already endorse fertility preservation (FP) through cryopreservation (i.e., “freezing” egg and sperm) for transgender individuals. Despite these endorsements from the relevant medical societies, medical insurance coverage for FP remains very limited in the US. Given (...) the high out-of-pocket costs for FP services, fertility preservation remains financially out of reach for many transgender individuals who may desire it. We present an ethical justification for universal FP coverage for all transgender and gender diverse (TGD) individuals who request this option during medically assisted gender transition. First, we argue that gender-affirming medical care is analogous to other medical interventions and treatment regimens that compromise fertility, such as cancer care, and that both types of interventions need to be afforded the same medical benefits and assistance in pursuing fertility goals. Second, we argue that the lack of FP for transgender individuals contributes to the ongoing and profound transphobia and anti-trans bias that has been exacerbated in the past several years across the healthcare landscape in the United States. We argue that the provision of FP coverage for transgender individuals is necessary for clinicians and third-party payers to state their unequivocal support for TGD patients and their healthcare needs.
