Luteinizing hormone (LH) is a primary regulatory hormone of the menstrual cycle, as evidenced by its role in stimulating ovarian follicle growth [1], triggering ovulation {fact:2, fact:4, fact:12}, and maintaining cycle regularity {fact:3, fact:5, fact:11}.

measurementDuring the early follicular phase of the menstrual cycle, Luteinizing hormone (LH) secretion occurs at a pulse frequency of 60 to 90 minutes with relatively constant pulse amplitude.
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.
claimAndrogens, glucocorticoids, and pituitary hormones (excluding LH and FSH) exhibit only minimal fluctuation during the normal menstrual cycle.
claimLuteinizing hormone (LH) receptors are located on theca cells during all stages of the 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 ovulatory phase occurs during days 13-15 of the menstrual cycle, where a significant increase in luteinizing hormone (LH) triggers the release of an egg.
claimThe female menstrual cycle relies on Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), estrogen, and progesterone for regularity.

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.
