Infertility Education - Evaluating Ovarian Functions

 

The first step in a fertility evaluation is assessing a woman’s ovarian function. The ovaries play a very important role and have two main tasks:

  • To produce eggs (oocytes) for fertilization. Specifically, one mature egg each month so that it can be fertilized.
  • To produce estrogen and progesterone. Both of these hormones are essential to obtaining and sustaining a healthy pregnancy.

A woman is born with all the eggs she will have in her lifetime (approximately 6-7 million). As a woman ages, egg reserve declines until there is a total depletion of eggs, resulting in menopause.


Assessment of Ovarian Reserve

 There are several ways in which we determine ovarian function:

  • Anti-Mullerian Hormone (AMH) level - AMH is a marker that indicates ovarian reserve.

    • Determining AMH levels requires a blood test
    • Normal AMH levels are between 1 - 3
    • An AMH of < 1 may indicate diminished ovarian reserve, but this may vary based on a patient’s age
    • An AMH > 3 may indicate PCOS (Polycystic Ovarian Syndrome)
    • It is important to note that AMH levels do not determine if a woman will become pregnant

 

  • Follicle Stimulating Hormone (FSH) & Estradiol (Estrogen) – Both FSH & Estradiol hormones provide another indication of properly functioning ovaries.
    • Both of these levels are taken by blood draw between day 2 and 4 of your menstrual cycle
    • An FSH of > 10 and/or an Estradiol level of > 70 may indicate reduced ovarian reserve

 

  • Antral Follicle Count (AFC) - Antral follicles are tiny follicles seen only through an ultrasound. AFC is a good predictor of the number of follicles that will respond to stimulation medication.
    • An assessment of the AFC via transvaginal ultrasound is given on day 3 of the menstrual cycle

 

It is important to remember that while ovarian reserve testing is a crucial part of the infertility evaluation, the testing is not definitive. It should be viewed as a screening test of ovarian reserve. The results of testing should not be used in determining whether or not a patient can undergo treatment. The true test of ovarian reserve is a stimulated cycle. While this information is helpful, there are many other factors that must be taken into account.
