Answer 2

Answer

Two hormones crucial to normal reproductive function are luteinising hormone (LH) and follicle-stimulating hormone (FSH). The levels of these hormones increase gradually from the ages of 9-12 and then more sharply during the early teenage years.

Their main hormones—estrogen and progesterone—ensure proper female development ... The ovaries, like their male counterpart, the testes, are known as gonads. ... These patients usually have high free testosterone levels.
