Answer
Hormones play a fundamental role in initiating and regulating reproductive function during adolescence. When a child reaches puberty, the hypothalamus in the brain signals the pituitary gland to release hormones that stimulate the reproductive organs. In males, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) trigger the testes to produce testosterone and begin sperm production. In females, these same hormones stimulate the ovaries to produce estrogen and progesterone and begin the menstrual cycle. These sex hormones not only enable reproduction but also trigger the development of secondary sexual characteristics, marking the transformation from child to sexually mature adult.
