Luteinizing hormone (LH, also known as luteinising hormone, [1] lutropin and sometimes lutrophin [2]) is a hormone produced by gonadotropic cells in the anterior pituitary gland. The production of LH is regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus. [ 3 ]
The luteal phase is characterized by changes to hormone levels, such as an increase in progesterone and estrogen levels, decrease in gonadotropins such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH), changes to the endometrial lining to promote implantation of the fertilized egg, and development of the corpus luteum. In the ...
The ranges denoted By biological stage are the 90% prediction intervals for hormone levels for women at the same biological stage. These reference ranges may be used in closely monitored menstrual cycles in regard to other markers of its biological progression, with the time scale being compressed or stretched to how much faster or slower ...
Similarly, a “normal” estrogen level ranges from 30 to 300, and there’s no data that says being closer to 30 or closer to 300 is better for you because every person reacts differently to ...
"Providers are encouraged to consult with their local lab(s) to obtain hormone level reference ranges for both 'male' and 'female' norms, [which can vary,] and then apply the correct range when interpreting results based on the current hormonal sex, rather than the sex of registration." Fenway Health: United States: 100–200 pg/mL <55 ng/dL
The diagrams below take inter-cycle and inter-woman variability into account in displaying reference ranges for estradiol, progesterone, FSH and LH. Levels of estradiol (the main estrogen), progesterone , luteinizing hormone and follicle-stimulating hormone during the menstrual cycle.
Testing serum LH and FSH levels are often used to assess hypogonadism in women, particularly when menopause is believed to be happening. These levels change during a woman's normal menstrual cycle, so the history of having ceased menstruation coupled with high levels aids the diagnosis of being menopausal.
