Testosterone therapy involves supplementing the hormone testosterone, which is important for sexual and reproductive development in men. Reasons it may be used include:
- Low testosterone levels (hypogonadism): This can cause symptoms like low sex drive, erectile dysfunction, decreased energy, and mood changes. Testosterone therapy can help restore normal levels.
- Difficulty fathering a child due to low sperm production: Testosterone therapy can help improve fertility in some cases.
- Loss of muscle mass due to aging or other conditions: Testosterone therapy may help regain some lost muscle, especially when combined with exercise.
