Androgens are used to treat low testosterone levels, delayed puberty in boys, and certain types of breast cancer in females. Androgens work by mimicking the effects of natural testosterone in your body, helping to develop and maintain male characteristics and muscle mass. These medications come in different forms, including oral pills, gels, and injections. Examples include testosterone cypionate (Depo-Testosterone), testosterone (Androgel, Testim, Fortesta, Vogelxo), testosterone enanthate, and danazol.
