Hormone replacement therapy (HRT) is a form of hormone therapy that uses sex hormones and other hormonal medications for gender transitioning. This form of hormone therapy is given as one of two types, based on whether the goal of treatment is masculinization or feminization:
Non-binary people may also engage in hormone therapy in order to achieve a desired balance of sex hormones or to help align their bodies with their gender identities. Many transgender people obtain hormone therapy from a licensed health care provider and others obtain and self-administer hormones.
Femboys may also occasionally engage in hormone therapy in order to develop breasts while still retaining a male gender identity.
