Estrogen and the pituitary gland are linked through a feedback loop where the pituitary gland produces hormones like FSH and LH that regulate estrogen production {fact:4, fact:7, fact:8}, while estrogen levels in turn signal the pituitary gland to adjust its hormone output {fact:1, fact:2, fact:3, fact: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.
Follicular Phase Of Menstrual Cycle - Cleveland Clinic my.clevelandclinic.org 2 facts
claimHigh estrogen levels toward the end of the follicular phase trigger the pituitary gland to release a surge of luteinizing hormone (LH), which causes the mature egg to be released from the follicle and ovary during ovulation.
claimIncreased estrogen levels trigger the pituitary gland to decrease the production of follicle-stimulating hormone (FSH), causing non-dominant follicles to wither and be reabsorbed by the body.

claimThe rise in estrogen during the follicular phase is stimulated by follicle-stimulating hormone (FSH) produced by the pituitary gland, and this estrogen promotes the growth of the uterine lining in preparation for pregnancy.
claimThe hypothalamus, pituitary gland, and ovaries are the biological sources of the hormones FSH, LH, estrogen, and progesterone.

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.
