Testosterone is a hormone that is primarily produced in the testicles in males and ovaries in females. It plays a key role in the development of male physical characteristics, such as muscle mass, body hair, and a deeper voice. It also contributes to the regulation of sex drive, bone density, and red blood cell production in both males and females.
Testosterone levels naturally decline with age, but imbalances can cause varios health issues, such as infertility, low sex drive, and mood disorders. Testosterone replacement therapy may be used to address these imbalances.
