[Decision-making in gender reassignment surgery].

The prescribing of hormones and the performing of gender reassignment surgery on a healthy body are dangerous and irreversible acts. To ensure patients' safety, endocrinologists and surgeons must use the skills of experienced psychiatrists to create a differential diagnosis, evaluate any frailties and weigh up the risk-benefit ratio. Therapeutic decisions are made as part of multidisciplinary consultation meetings. A minimum two-year observation period must be respected for the treatment to be covered by social security.
