Estrogen and FSH are intrinsically linked within the menstrual cycle, where FSH stimulates the ovaries to produce estrogen [1], [2], while rising estrogen levels exert negative feedback to inhibit the secretion of FSH [3], [4], [5].

claimIf estrogen levels drop early during the perimenopausal phase, the pituitary gland produces more FSH, which is the hormone measured in fertility tests.
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.

claimAs estrogen levels rise during the follicular phase, the hormone acts as a switch to turn off the production of follicle-stimulating hormone (FSH), limiting the number of follicles that prepare eggs for release.

claimAs a dominant follicle grows, blood levels of estrogen rise significantly by cycle day seven, which inhibits the secretion of FSH and causes smaller follicles to die off.

claimLuteinizing hormone (LH) and follicle-stimulating hormone (FSH) promote ovulation and stimulate the ovaries to secrete the sex hormones estradiol (an estrogen) and progesterone.
