Transfeminine Science is a resource for original informational content on the subject of transfeminine hormone therapy. This form of hormone therapy is also known variously as feminizing hormone therapy (FHT), gender-affirming hormone therapy (GAHT) for transfeminine people, and—more in the past—male-to-female (MtF) hormone replacement therapy (HRT). It involves the use of female sex hormones including estrogens and progestogens—as well as androgen-opposing medications known as antiandrogens—to produce feminization, demasculinization, and alleviation of gender dysphoria in transgender women and non-binary transfeminine individuals.
