We measure 5 key hormones that can affect your menstrual cycle and ovulation
Your results will provide a detailed breakdown of the 5 hormones below and let you know whether your levels fall within the typical range.
EstradiolEstradiol, the primary form of estrogen for those who can become pregnant, is produced by the ovaries. Essential for regulating ovulation, and a key hormone in pregnancy, estradiol's importance goes beyond reproduction. It contributes to the development of strong bones, the formation of female secondary sex characteristics (such as breast development), and even supports optimal brain function. After menopause, estradiol levels naturally decline, which can lead to various changes in the body.
Luteinizing hormoneLuteinizing 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 hormoneFollicle-stimulating hormone (FSH), is produced by the pituitary gland and plays an essential role in the growth and maturation of ovarian follicles, as well as in ovulation and the menstrual cycle. Baseline FSH levels typically increase with age due to diminished ovarian reserve, and over time more FSH is 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.
Thyroid-stimulating hormoneThyroid-stimulating hormone (TSH), is produced by the pituitary gland and is responsible for controlling the production of the thyroid hormones T3 and T4 by the thyroid gland. TSH is considered the most sensitive marker for screening for thyroid diseases and conditions.
Total TestosteroneIn people assigned female at birth (AFAB), testosterone is primarily produced by the ovaries, with a small amount produced by the adrenal glands. A large portion of this testosterone is converted to estrogen by an enzyme called aromatase. Total Testosterone is a measurement of both free testosterone and testosterone that is bound to the proteins albumin and sex hormone-binding globulin in the blood. While commonly regarded as a male sex hormone, testosterone is important for bone density, libido, body fat distribution, and supporting muscle mass across all sexes.
