Planning Your Reproductive Future

Egg supply is one of the critical factors affecting fertility. While most women are born with 1–2 million eggs, by age 30 the average female has 12% of her original egg count, and just 3% remain by age 40.

There are many factors that can influence egg supply, including inherited predispositions, environment, lifestyle choices and medical conditions. You are unique, and so is your fertility and reproductive health, even among women of similar age.

The Ovarian Assessment Report (OAR™) from ReproSource® is a test designed to predict your remaining egg supply. Understanding your egg supply can help you make an informed decision about the best time to plan for pregnancy and whether to explore other reproductive options.

How does the OAR test work?

The OAR test provides a reliable estimate of your egg supply by measuring levels of ovary-related hormones such as FSH and AMH in the blood, and linking these results to clinical fertility studies related to egg supply. Additionally, the OAR test supplies an easy-to-understand Egg Supply Score.

How is the test performed?

A single tube of blood is collected on days 2–4 of your menstrual cycle, and is sent to the laboratory for analysis. Your healthcare provider will receive a report that includes your Egg Supply Score, and he or she will review the results with you.

For the most accurate results, hormonal contraceptives should not be used for at least eight weeks prior to testing.

What will the OAR test tell me?

Knowing your Egg Supply Score can help you learn about your personal fertility window and aid with reproductive planning.

If your Egg Supply Score is low but you are not ready to conceive, you may want to consider alternate reproductive options including egg preservation that can extend your fertility timeline. Your healthcare provider can recommend the best fertility treatment options based on your family plan and medical history.

Is the OAR test right for me?

The OAR test may benefit any woman 25 years or older who is interested in assessing her reproductive planning and health options.

Ovarian reserve testing is recommended by the American College of Obstetricians and Gynecologists for women over the age of 35 who have attempted pregnancy for six months or longer without success, and for women at increased risk of diminished ovarian reserve. Risk factors include:

  • Age >35 years and desiring pregnancy
  • Ovarian surgery (e.g. removal of cyst or endometrioma)
  • Conditions damaging to ovaries (e.g. endometriosis, pelvic inflammation)
  • Exposures toxic to ovaries (e.g. chemotherapy, pelvic irradiation)
  • Family history of early menopause
  • Smoking
  • Genetic factors (e.g. Turner syndrome mosaic, Fragile X carrier)

What are the test limitations?

The OAR test predicts your remaining egg supply. Understanding your egg supply will not measure egg quality, predict pregnancy success rate or determine the health status of the fetus.

Your healthcare provider may recommend additional testing or procedures, such as a transvaginal ultrasound to obtain further information.

Talk to your healthcare provider to find out if this test is right for you.
