Progesterone and the pituitary gland are linked through the hormonal regulation of the menstrual cycle, where progesterone levels signal the pituitary gland to release FSH [1], and both are identified as key components of the hypothalamic-pituitary-ovarian axis [2].

claimAt the start of the menstrual cycle, low levels of estrogen and progesterone signal the pituitary gland to release follicle-stimulating hormone (FSH), which stimulates the growth of ovarian follicles.

procedureThe menstrual cycle proceeds in five steps: (1) The pituitary gland produces FSH, which signals the ovaries to produce estrogen. (2) When estrogen reaches a specific level for a set duration, the pituitary gland produces LH. (3) LH triggers ovulation, causing the ovary to release an egg into the fallopian tube. (4) The ovary produces progesterone to prepare the uterus for pregnancy. (5) If conception does not occur, hormone levels drop, the menstrual lining stops developing, and the lining is shed as a menstrual period.

claimIn the presence of estradiol, follicle-stimulating hormone (FSH) stimulates the formation of luteinizing hormone (LH) receptors on granulosa cells, allowing for the secretion of small quantities of progesterone and 17-hydroxyprogesterone (17-OHP), which may exert a positive feedback on the estrogen-primed pituitary to augment LH release.
