About testosterone

Testosterone is a medication and naturally occurring steroid hormone. It is used to treat male hypogonadism, gender dysphoria, and certain types of breast cancer. It may also be used with the intent to increase athletic ability in the form of doping. It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful. Testosterone can be administered through several different routes, including topical gels or patches, nasal sprays, subdermal implants, or tablets dissolved inside the mouth. Testosterone therapy has been associated with improvements in depressive symptoms, increased exercise capacity and muscle strength in men with chronic heart failure, and male contraception effectiveness.
