Testosterone and Replacement
What is Testosterone?
Testosterone is a sex hormone produced by the testes that stimulates the development of male sexual characteristics, such as the penis and testes, muscle size, vocal cords and bones, pubic hair, facial hair and the Adam’s apple. Production of testosterone in the testes is controlled by the brain and pituitary gland.
What Are the Symptoms of Low Testosterone?
The symptoms of low testosterone, also known as hypogonadism, are often overlooked because they are mistaken for ordinary signs of aging. Men with below-normal testosterone may experience the following symptoms:
- low interest in sex
- muscle weakness
- small or soft testicles
- erectile dysfunction
- weight gain, particularly around the waist
- reduced bone density
Low testosterone can be resolved in a number of different ways.
