What’s My Fertility requires three blood tests in order to determine your risk of developing premature ovarian aging (POA):

  • Anti-Müllerian hormone (AMH): AMH is a hormone secreted by the follicles (sacs in the ovaries that contain eggs) at the very early stages of the eggs’ maturation journey. AMH can tell us how many immature eggs are being recruited into the maturation process. When AMH is lower than the level expected for a woman’s age, that is a signal that she may have fewer eggs left in the ovaries than normal, putting her at risk of POA.
  • Follicle stimulating hormone (FSH): FSH is a hormone that encourages the development of eggs. In return, eggs that are close to maturity give a feedback signal to reduce the amount of FSH secreted from the pituitary. When there aren’t as many eggs nearing maturity as there should be, FSH rises, trying to nudge more eggs into the development process. So, a higher level of FSH than expected for her age suggests that the woman may be at risk of POA.
  • Fragile X Mental Retardation 1 gene (FMR1): Through research, What’s My Fertility’s physicians have discovered that women with certain types of the FMR1 gene are at increased risk of POA.

Of these 3 blood tests, AMH and FMR1 are required. While FSH is not, we highly recommend that you get this hormone level tested for a more accurate assessment of your POA risk.

What if I don’t have these labs? Can I still use What’s My Fertility?

Yes! We offer a free preliminary screening with no blood tests required. This assessment is based on your medical and family history, and can tell you whether you’re at a low, medium, or high risk of developing POA in the future. However, it cannot give you a definitive picture of your POA risk, nor can it tell you whether you have POA right now. We recommend that all women using What’s My Fertility submit lab tests.


Can I go through the screening if I’m using birth control?

Yes, in some cases. If the birth control method you are using is hormonal, meaning it uses estrogen and progestin, it can interfere with your blood test results. While you can still go through the screening, we do recommend that you switch to using other methods of contraception for 3 months before undergoing the lab tests. Hormonal contraceptives include:

  • Oral contraceptive pills
  • Patches
  • Vaginal rings
  • Hormone-releasing IUDs (intrauterine devices)
  • Injections
  • Implants

Non-hormonal birth control, like male and female condoms, non-hormonal/copper IUDs, etc., do not interfere with the results of your screening. If you are unsure, contact us online, and we’ll help you figure out whether yours is a hormonal contraceptive.

Even if you’re using a hormonal contraceptive, you can still take our preliminary screening for free and with no lab tests required.


I got the lab results. Which numbers do I enter into the What’s My Fertility portal?

You’ll need to enter your FSH, AMH and FMR1 results. The guide below explains how to read your lab report, and which numbers to enter into the portal.


How much does it cost to take these three blood tests?

Once you’ve registered, What’s My Fertility will write you a prescription for testing at LabCorp, which will cost $274. We have negotiated this lower price with LabCorp for What’s My Fertility users. You’ll pay the testing fee to What’s My Fertility, and we’ll give you your prescription to bring to LabCorp. (FYI, What’s My Fertility doesn’t add any fees—this is what LabCorp charges us or your blood tests.)

If you’d like to use your health insurance to cover the cost of your blood tests, you can get them done by your primary care physician or your OBGYN. This may be a cheaper option for you if your insurance covers lab testing. If you’d like to get your labs this way, select the “I have my labs” option when you register, get your blood tests done, and then input the results into the What’s My Fertility portal.
