'Sexy' Hormones

Testosterone - The 'Sexy' Hormone

A product of DHEA and progesterone, testosterone takes credit for the human sex drive - or lack of, as the case may be. Testosterone is the most critical hormone involved in the human sex drive - in both men and women. Testosterone also supports bones and muscle, as well as the cardiovascular system.

At puberty and throughout the reproductive years, approximately twenty times more testosterone is produced in males than in females.

Through childhood development and male puberty, testosterone along with DHT (dihydrotestosterone) are responsible for the development of secondary male sexual characteristics such as:

* Increased muscle and bone mass
* Hair growth
* Sperm production
* Genital size
* Male behavior

Testosterone levels reach their peak in twenty to thirty year old males and decline with each passing decade. In men, low testosterone levels have been linked to:

* Decreased sex drive
* Impotency
* Infertility
* Abnormal breast enlargement
* Fatigue
* Depression
* Lowered motivation
* Irritability
* Weight gain
* Decreased body hair
* Shrinking of the testes
* Anemia
* Thinning of the skin with increased wrinkle development
* Decreased muscle size and strength
* Increased risk for osteoporosis and prostate cancer

In females, testosterone is required for:

* Proper musculo-skeletal development
* General anabolic activity
* Libido

Testosterone is the most important hormone for maintaining a sex drive in women and a deficiency can cause impaired sexual function.

Testosterone decreases with age in both men and women, and supplementation has been used successfully for the treatment of some post-menopausal symptoms such as:

* Lack of libido
* Anemia
* Muscle weakness

Testosterone supplementation has been shown to cause a gain in lean body mass and a possible decline in bone loss when used in elderly patients.
