What is testosterone?
Men produce the hormone testosterone in their testes. Testosterone helps in the following:
- Increases bone density
- Fat distribution
- Muscle mass
- Muscle strength
- Red blood cell production
- Sex drive
- and in men it is responsible for sperm production
Your doctor can prescribe a synthetic version of testosterone. Testosterone therapy using testosterone replacement medications may be necessary for men who have very low levels of testosterone (hypogonadism). Testosterone therapy medications are available as injections, patches and gels.
