How are follicle-stimulating hormone levels controlled during the menstrual cycle and what mechanisms regulate its rise and fall?
FSH levels are regulated by the hypothalamic-pituitary-gonadal axis. GnRH from the hypothalamus stimulates the pituitary to release FSH, which is inhibited by inhibin from the ovaries and stimulated by rising estrogen levels.
FSH levels are regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus and inhibited by estrogen and inhibin from the ovary.
