Correct Answer - Option 1 : Testosterone

The correct answer is Testosterone.

  • Testosterone is the only male sex hormone present in the human body, which causes physical changes in puberty, increases bone density and muscle mass, growth of facial, pubic, and body hair, deepening of the voice, and also responsible for sexual and reproductive development.
  • Testosterone is the main sex hormone in men, which is 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.
