Detailed explanation-1: -In children, FSH levels are usually low until puberty, when levels begin to rise. In girls, it helps signal the ovaries to make estrogen. In boys, it helps signal the testes to make testosterone.
Detailed explanation-2: -Following puberty, the anterior pituitary begins to secrete FSH and LH in response to GnRH release from the hypothalamus, and the dormant cells in the ovary begin to secrete steroid hormones in response.
Detailed explanation-3: -When GnRH reaches the pituitary gland (a pea-shaped gland that sits just under the brain), this gland releases into the bloodstream two more puberty hormones: luteinizing hormone (LH for short) and follicle-stimulating hormone (FSH for short). Guys and girls have both of these hormones in their bodies.
