Testosterone is a hormone produced by the gonads - testes in males and ovaries in females - plus a very small amount is also produced by the adrenal glands by both genders.
Testosterone is the main sex hormone in males, which gives men their sexual characteristics (that differentiate them from women).
- Testosterone is made by the interstitial cells of the testes
- Testosterone is an anabolic steroid hormone
- Testosterone is synthesised from cholesterol
- Testosterone affects most cells in the body
- The adult male produces around 8-10 times more testosterone than the adult female
- Testosterone plays a major part in health and well-being of both males and females
- Testosterone enhances libido, energy, immune function, and provides protection against osteoporosis
Testosterone is required for the following processes in the male body mainly, but also the female body too:
- Development and regulation of the reproductive structures
- Producing the sexual organs and characteristics - facial and body hair, depth of voice, sexual organs
- Protein synthesis
- Growth of adam's apple
- Maintenance of muscle mass and strength
- Increased mental and physical energy
- Promotion of the sex drive
Higher testosterone levels in the male body have an enlarging effect on the organs.
