Androgen hormones are vital to the development and management of male characteristics in the human body. The principal hormone in this group is testosterone, an anabolic steroid hormone. Anabolic steroid hormones promote the retention of protein in the body, contribute to muscle mass, bone strength, bone density and more.

Testosterone plays a key role in the growth and development of young men, as well as contributes to energy, muscle strength, maintenance of lean body mass, sex drive, and much more in both genders. Obviously, testosterone production is higher in men than women, so characteristics like muscle mass and strength are generally more pronounced in men. And unfortunately for many men, testosterone levels begin to decline around the mid to late twenties and continue to diminish as a man ages.

Low testosterone can affect a man's health, body and mind, making activities of daily living frustrating. The good news is that men suffering from low levels of testosterone do not have to live with the distress. There are ways to boost low testosterone levels, including testosterone replacement therapy, dietary changes, routine exercise and nutritional supplements.
