Used primarily in hormone therapy for transgender women to reduce testosterone levels and promote feminization. It acts as an anti-androgen, blocking the effects of male hormones and helping to decrease facial and body hair growth, reduce muscle mass, and support breast development when combined with estrogen. Commonly prescribed in the treatment of androgen-dependent conditions such as acne, hirsutism, and alopecia in women. It helps regulate excessive male hormone activity that contributes to these conditions. Also used in the management of prostate cancer in men, where suppressing testosterone activity slows tumor growth. Its strong anti-androgenic properties make it effective in reducing symptoms and disease progression in certain cases. Has been used as a component in birth control pills in some countries, particularly in combination with estrogen, to regulate menstrual cycles and treat conditions like endometriosis. In high doses, it can act as a chemical castration agent, used in the treatment of hypersexuality or paraphilias in some clinical settings, though this application is less common and subject to ethical considerations.
