A hormone is a substance made by one tissue and carried by the bloodstream to a tissue elsewhere in the body. Male sex hormones are known as androgens.
Androgens affect the growth and function of the male reproductive organs.
They govern sexual behavior, as well. Androgens are closely related to other hormones that regulate growth and metabolism. Male hormone disorders are generally related to a deficiency of testosterone. Seek medical care if you have any of these symptoms. A blood test can determine the blood hormone levels.
