Testosterone the male hormone
Testosterone is one of the most important hormones in men and is mainly produced in the testicles. It is responsible for muscle growth, bone mass and to stimulate sperm production.
Testosterone levels also affect your sexual drive.
Normal testosterone levels vary. Adult males are considered to have low testosterone when its levels fall below 300 nanograms per deciliter (ng / dL), according to the guidelines of the American Urological Association (AUA)
Decreased testosterone is normal with aging.
Decreased testosterone can lead to decreased libido and erectile dysfunction.
