Estrogen and luteinizing hormone (LH) are both key hormones that regulate the menstrual cycle {fact:3, fact:10, fact:13}. Specifically, rising estrogen levels provide the feedback necessary to trigger the surge of luteinizing hormone (LH) that causes ovulation {fact:1, fact:11, fact:19, fact:20}.

claimThe female menstrual cycle relies on Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), estrogen, and progesterone for regularity.

claimDisruptions in the hormones FSH, LH, estrogen, or progesterone can lead to irregular periods or fertility issues.

claimThe hypothalamus, pituitary gland, and ovaries are the biological sources of the hormones FSH, LH, estrogen, and progesterone.

claimOvulation is marked by a spike in Luteinizing Hormone (LH) and a secondary estrogen peak.

claimDuring the ovulation phase, estrogen levels peak, triggering a spike of luteinizing hormone (LH), which causes the release of the mature egg from its follicle into the fallopian tube towards the uterus.

claimWhen estrogen levels reach their peak, they trigger the release of luteinizing hormone (LH) from the brain, which causes the egg to be released from the follicle.

claimThe menstrual cycle is guided by shifts in estrogen, progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH).

claimThe menstrual cycle is regulated by fluctuations in the hormones estrogen, progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH).

claimThe postovulatory decline in luteinizing hormone (LH) may be caused by the loss of the positive feedback effect of estrogen, the increasing inhibitory feedback effect of progesterone, or the depletion of pituitary LH content due to downregulation of GnRH receptors.

referenceA 1978 study published in the American Journal of Obstetrics and Gynecology examined the temporal relationships of estrogen, progesterone, and luteinizing hormone levels to ovulation in women and infrahuman primates.

claimLuteinizing hormone (LH) levels are low during the early follicular phase of the menstrual cycle and begin to rise by the mid-follicular phase due to positive feedback from rising estrogen levels.

claimThe menstrual cycle is regulated by the hormones follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, and progesterone.

claimDuring the early follicular phase, rising estrogen levels suppress luteinizing hormone to ensure the body's preparation for ovulation is gradual.

claimJust before ovulation, the body experiences a sharp rise in luteinizing hormone (LH) and a smaller rise in estrogen, which triggers the release of a mature egg from the dominant follicle.

claimFollicle-stimulating hormone (FSH) and luteinizing hormone (LH) trigger an increase in estrogen production in the ovaries.

procedureDuring the ovulatory phase, the rise in estrogen from the dominant follicle triggers a surge in luteinizing hormone (LH) production by the brain, which causes the dominant follicle to release its egg from the ovary.

claimEstrogen, progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) regulate the menstrual cycle by signaling the brain, ovaries, and uterus.

claimA sudden surge in luteinizing hormone (LH) triggers the release of the egg during ovulation, and estrogen levels drop immediately after this event.

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.

claimA sufficiently high level of estrogen triggers a sudden release of LH, usually around day thirteen of the cycle, which results in final egg maturation and follicular collapse.

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.
