13 MayHow Our Bodies Use Testosterone?
What is testosterone?
Testosterone is often called the “male” hormone. However, both men and women produce this hormone. Hormones are molecules that regulate the body. They are usually produced in one location in the body and travel to other organs. Other hormones in the body include growth hormone and thyroid-stimulating hormone.
Testosterone is an androgen hormone. It produces male characteristics in the body. Testosterone is made in the following locations:
- testes in men
- ovaries in women
- the adrenal glands, located above the kidneys in both men and women
Men have higher levels of testosterone in their bodies than women do. In either sex, if testosterone levels become imbalanced, adverse symptoms can occur.
How is testosterone used in men and women?
Testosterone is responsible for many actions in the male body throughout a man’s life cycle. It helps the external and internal organs of a male fetus develop. This includes the male reproductive organs such as the penis and testicles. During puberty, testosterone is responsible for:
- growth spurts
- deepening of the voice
- growth of hair in the pubic region, face, and underarms
Testosterone is also associated with behaviors such as aggression and sexual drive. Men need testosterone to make sperm for reproduction.
In women, testosterone also contributes to a woman’s sex drive. It also helps to secrete hormones important in a woman’s menstrual cycle.
Testosterone also plays common roles for both sexes. For example, the hormone stimulates the body to make new red blood cells. Testosterone can also affect a man’s bone density, fat distribution, and muscle strength.
