Testosterone plays a major role in a man's sexual desire and physical appearance.

Sexual desire

Testosterone is one of the main hormones responsible for male sex drive, or libido. It increases sexual thoughts and feelings, and it also helps to produce erections. Men with low testosterone levels often experience a decrease in libido.

Physical appearance

Testosterone also plays a role in a man's physical appearance. It helps to promote the development of male sex characteristics during puberty, such as facial and pubic hair, a deeper voice, and increased muscle mass. Testosterone also helps to maintain bone density and prevent muscle loss.

Here are some of the specific ways that testosterone affects a man's physical appearance:

• Muscle mass and strength. Testosterone helps to build and maintain muscle mass. It also increases muscle strength and power.
• Bone density. Testosterone helps to maintain bone density and prevent osteoporosis.
• Body fat distribution. Testosterone helps to promote a more masculine body fat distribution, with less fat in the hips and thighs and more fat in the abdomen.
• Facial and body hair. Testosterone is responsible for the growth of facial and body hair.
• Skin. Testosterone helps to keep the skin thick and healthy. It also helps to produce sebum, which is an oily substance that helps to protect the skin.

Men with low testosterone levels may experience a number of changes in their physical appearance, such as:

• Decreased muscle mass and strength
• Increased body fat, especially in the hips and thighs
• Reduced facial and body hair
• Thinning skin
• Erectile dysfunction

If you are concerned about your testosterone levels or your physical appearance, talk to your doctor. They can test your testosterone levels and recommend the best course of action for you.
