There are different types of hormones, which are naturally produced and secreted by the endocrine glands and other organs of the human body. These hormones function as messengers by carrying signals within the body from one part of the body to another.

Testosterone is the main sex hormone in men, which are naturally produced in the testes and in small amounts by the adrenal glands.

Testosterone belongs to a class of male hormones called androgens, which are also known as steroids. The production of male sex hormones is mainly controlled by the hypothalamus and pituitary gland. The testosterone levels gradually decrease with age, which results in impotence, shrinking of testes, low sperm count, depression, mood swings, irritability, etc.
