Cyproterone acetate is primarily used in the treatment of androgen-dependent conditions. It is commonly prescribed to manage symptoms of prostate cancer by reducing the levels of male hormones that can fuel cancer growth. In addition, it is widely utilized in hormone therapy for transgender women to suppress testosterone production and facilitate feminization. The compound is also effective in treating conditions like severe acne, hirsutism, and alopecia in women, where excessive androgen activity is a contributing factor. Furthermore, it is a key component in certain oral contraceptives, helping to regulate hormonal imbalances and reduce symptoms of polycystic ovary syndrome (PCOS). Its anti-androgenic properties make it a versatile therapeutic agent in both oncology and endocrinology.
