Testosterone is a steroid hormone from the androgen group. It is derived from cholesterol, like other steroid hormones, and is created by the Leydig cells in the testes.

It is responsible for many significant functions in your body. It is needed for sex drive not only in males, but in females as well. The testosterone is responsible for the normal development of sex organs in men, for the production of sperms, as well as the development of male characteristics during puberty including deep voice and facial hair.

 How Testosterone Boosters Affect the Body?

Testosterone boosters can help maintain testosterone levels during continued training. During a workout, testosterone levels usually rise after about 30 minutes of resistance exercise. Competitive and heavy endurance training, however, can reduce testosterone levels as the body adapts to the changes in hormone levels.

This reduction hinders performance after a while and slows the muscle-building process. So, maintaining peak testosterone levels is accomplished using testosterone boosters.

What causes Testosterone Deficiency?

As a man ages, the amount of testosterone in his body gradually declines. This natural decline starts after age 30 and continues throughout life. The significance of this decline is controversial and poorly understood. Among the potential causes of testosterone deficiency are: Injury or infection to the testicles, chronic illness, AIDS, chemotherapy or radiation treatment for cancer.
