This test measures levels of 3 hormones known to shift during the menopausal transition.

Your blood test results will provide detailed information on whether the 3 hormones measured fall within established normal ranges. Many of the symptoms women notice during the menopausal transition are due to changing hormone levels, so this test may help you better understand the perimenopause symptoms you are experiencing.

Estradiol

Estradiol is the main form of estrogen in people assigned female at birth (AFAB) and is produced by the ovaries. It is one of the main sex hormones responsible for ovulation, which is vital to reproductive health and pregnancy in people who can get pregnant. After menopause, levels of estradiol decline significantly. Estradiol also plays a role in the development of bones and female-associated secondary sex characteristics development, as well as the optimal functioning of the brain and reproductive system.

Luteinizing Hormone

Luteinizing hormone, or LH, is a hormone produced in the pituitary gland that is responsible for the stimulation and maturation of ovarian follicles in the ovaries. Ovarian follicles are small, fluid-filled sacs in the ovary that contain an immature egg. When an egg matures during the menstrual cycle, the follicle breaks open and releases the egg from the ovary for possible fertilization.

Follicle-Stimulating Hormone

Follicle-stimulating hormone, or FSH, is a hormone produced by the pituitary gland in the brain, which plays an essential role in the growth and maturation of ovarian follicles, as well as with ovulation and the menstrual cycle. Baseline FSH levels typically increase with age due to diminished ovarian reserve, and over time more FSH is then needed to stimulate ovarian function. A normal FSH level may imply that a person with a uterus has an appropriate egg quantity for their reproductive stage.
