FSH is a primary hormone that regulates the menstrual cycle [1], specifically by signaling the ovaries to produce estrogen [2] and recruiting ovarian follicles {fact:1, fact:5}. Variations in FSH levels are directly linked to changes in the duration and progression of the menstrual cycle {fact:2, fact:8}.

claimThe elevation of FSH in the late luteal phase allows for the recruitment of a cohort of ovarian follicles in each ovary, one of which is destined to ovulate during the next menstrual cycle.
claimAndrogens, glucocorticoids, and pituitary hormones (excluding LH and FSH) exhibit only minimal fluctuation during the normal menstrual cycle.
referenceSherman B.M., West J.H., and Korenman S.G. published a 1976 study in the Journal of Clinical Endocrinology and Metabolism analyzing LH, FSH, estradiol, and progesterone concentrations during the menstrual cycles of older women.

claimThe menstrual cycle is regulated by the hormones GnRH, FSH, LH, estradiol, and progesterone.
claimThe recruitment stage of the menstrual cycle occurs during days 1 through 4, during which follicle-stimulating hormone (FSH) recruits a cohort of follicles from the pool of non-proliferating follicles.
claimDuring a normal menstrual cycle, androgens, glucocorticoids, and pituitary hormones (excluding LH and FSH) exhibit only minimal fluctuations in concentration.

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.
claimHigher FSH levels trigger earlier ovulation, which can cause a woman's menstrual cycle to shorten to 21 days during her late 40s.
