The Role Of Testosterone In Muscle building

1# What Is Testosterone?

    Testosterone is a steroid hormone from the androgen group. In mammals, testosterone is primarily secreted in the testes of males and the ovaries of females, although small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid. Testosterone is evolutionarily conserved through most vertebrates, although fish make a slightly different form called 11-ketotestosterone.

 2# Role Of Testosterone In Muscle Building: 


In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate as well as promoting secondary sexual characteristics such as increased muscle and bone mass and hair growth. In addition, testosterone is essential for health and well-being as well as preventing osteporeosis.
On average, an adult human male body produces about ten times more testosterone than an adult human female body, but females are, from a behavioral perspective (rather than from an anatomical or biological perspective), more sensitive to the hormone. However, the overall ranges for male and female are very wide, such that the ranges actually overlap at the low end and high end respectively.
Testosterone directly effects muscle growth by binding to receptors on the surface of muscle cells and amplifying the biochemical signals in muscle tissue that result in protein synthesis. Testosterone also increases levels of another growth factor, called growth hormone, that the body releases in response to exercise. Like testosterone, growth hormone increases protein synthesis and can result in increased muscle growth.


  1. Well fortunately there are plenty of highly nutritious and participating foods you can
    build into a meal plan that will facilitate your gain muscle.all you've got have to be compelled to outline your
    nutritional goal (mass gaining, cutting up, etc.) and then building a plan around

  2. It's quite interesting! There are some people who are encountered problems of less interest to sex and they are looking for supplements which help to increase testosterone levels.

  3. Weightlifting and strength training are the best forms of exercise that raise testosterone levels in the blood and build muscle strength. Declining testosterone can result in sagging and weak muscles. Ageless Male reviews indicate that men who use this supplement, eat a diet full of good fats and work out diligently are able to achieve optimum testosterone levels and good muscle mass.
