Testosterone (T) is a medication and naturally occurring steroid hormone.[8] It is used to treat male hypogonadism, gender dysphoria, and certain types of breast cancer.[8][9] It may also be used to increase athletic ability in the form of doping.[8] It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful.[10] Testosterone can be used as a gel or patch that is applied to the skin, injection into a muscle, tablet that is placed in the cheek, or tablet that is taken by mouth.[8]

Common side effects of testosterone include acne, swelling, and breast enlargement in men.[8] Serious side effects may include liver toxicity, heart disease, and behavioral changes.[8] Women and children who are exposed may develop masculinization.[8] It is recommended that individuals with prostate cancer should not use the medication.[8] It can cause harm to the baby if used during pregnancy or breastfeeding.[8] Testosterone is in the androgen family of medications.[8]

Testosterone was first isolated in 1935, and approved for medical use in 1939.[11][12] Rates of use have increased three times in the United States between 2001 and 2011.[13] It is on the World Health Organization's List of Essential Medicines.[14] It is available as a generic medication.[8] In 2021, it was the 143rd most commonly prescribed medication in the United States, with more than 4 million prescriptions.[15][16]
