Question

Quizplus · Accepted Answer

The hypothalamus releases gonadotropin-releasing hormone (GnRH), which stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland. FSH and LH then stimulate the ovaries or testes to produce sex hormones, which leads to the physical changes of puberty.
