what happens in a boy's body under the influence of sex hormones
Answers
Explanation:
In boys, the same hormones tell the testes to begin producing testosterone, the male sex hormone, and sperm. At the same time, you'll notice other significant changes: Both boys and girls will grow taller and put on weight and muscle mass.
Testosterone is the hormone that causes most of the changes in a guy's body during puberty. Sperm cells must be produced for men to reproduce. In girls, FSH and LH target the ovaries, which contain eggs that have been there since birth.
