The main male reproductive hormone is testosterone.

Production

Testosterone is primarily produced in the testes, specifically by the Leydig cells located in the interstitial tissue surrounding the seminiferous tubules. A smaller amount is also produced by the adrenal glands.

Role of Testosterone

Testosterone plays several critical roles in male development and reproductive function:

1. Development of Male Reproductive Tissues: Testosterone is essential for the growth and maturation of male reproductive organs, including the penis, testicles, and prostate.
2. Spermatogenesis: It stimulates the production of sperm within the testes. While testosterone is crucial for spermatogenesis, it works in conjunction with follicle-stimulating hormone (FSH) to optimize sperm production.
3. Secondary Sexual Characteristics: Testosterone is responsible for the development of secondary sexual characteristics during puberty, including:
   • Deepening of the voice
   • Growth of facial, pubic, and body hair
   • Increased muscle mass and strength
   • Changes in fat distribution
4. Sex Drive and Sexual Function: Testosterone influences libido (sex drive) and plays a role in erectile function. It also affects mood and energy levels.
5. Bone Density and Muscle Mass: It contributes to maintaining bone density and muscle mass throughout life, which is important for overall health.
