What hormones are responsible for libido?

Numerous factors can affect libido. Depression, anxiety, body image problems or a history of sexual abuse to extinguish sexual desire. Physical, such as illness, fatigue and the use of certain drugs problems can also reduce libido. Maintaining adequate levels of certain hormones is important for maintaining sexual desire alive in men and women.

Testosterone
The hormone testosterone plays a role in maintaining a healthy sex drive. Testosterone is most commonly associated with male characteristics, but is present in the female body as well, according to MedlinePlus. The hormone is produced by the Leydig cells of the testes in men and ovaries in women. The adrenal glands of both sexes also produce DHEA, a precursor of testosterone.

Testosterone is a masculinizing hormone. High levels of testosterone cause the voice to deepen and increase the development of muscle mass and strength. Testosterone increases libido in both men and women. Womenshealth.gov states that reduced levels of testosterone may decrease the ability of man to achieve erection, in addition to the decrease of interest in sex. Injuries, illnesses and use of certain drugs can lower testosterone levels.

Estrogen
The female hormone estrogen produced in the ovaries, and in certain fat cells. Estrogen induces the growth and development of the female sexual organs, pubic hair and breasts. A deficiency in estrogen can cause decreased sexual desire in women, according to MayoClinic.com. Both levels of the hormones estrogen and testosterone levels decline during menopause. Decreased estrogen results in vaginal dryness, which can also put a damper on sexual desire.

Not all women experience as a result of waning libido menopause. Many report satisfying sex lives well into their later years. Unfortunately, hormonal changes associated with this transitional phase of life make an impact on some women in ways that put the brakes on sexual intimacy.

Progesterone
Progesterone is produced in the ovaries during a period of about 11 days after ovulation every month. Breastcancer.org indicates that progesterone is one of the hormones that influence sexual desire of a woman. Treatment of breast cancer can alter the levels of progesterone, estrogen and testosterone in the body of a woman. Decreased levels of these hormones decrease a woman’s ability to become sexually aroused or achieving orgasm.
