What Is "Ovarian Age," and Why Did Longevity Research Ignore It for So Long?

Ovarian age is a measure of how many egg-containing follicles remain in your ovaries and how quickly that reserve is declining, and it is not the same thing as the number of birthdays you have had. Researchers estimate it using biomarkers like anti-Müllerian hormone (AMH) and antral follicle count, and some evidence suggests these markers may reflect more than reproductive timing alone. Mainstream longevity science spent decades studying the heart, brain, and metabolism while largely leaving the ovaries out of the conversation. That is starting to change, and it matters for more than just family planning.

What "ovarian age" actually measures

Unlike a birth certificate, ovarian age is not fixed. It is estimated through blood tests and ultrasound measurements that track the size of your remaining follicle pool, which shrinks over time at a pace that varies from woman to woman.^† Two women who are the same chronological age can have meaningfully different ovarian reserves.

AMH, in particular, has become the most widely used hormonal marker of this reserve. It does not diagnose infertility on its own, and ASRM's patient education materials are clear that no single ovarian reserve test can definitively predict whether or when a woman will get pregnant.

Why longevity research spent decades looking everywhere except here

For years, aging and longevity research concentrated on cardiometabolic and neurocognitive outcomes, the heart, the brain, blood sugar, cholesterol. Reproductive aging was treated as a separate, narrower topic that only mattered for fertility planning. A 2025 review in the journal Biology of Reproduction and Aging Research and Reviews notes that biomarkers of ovarian reserve are only now being proposed as part of structured panels for gerotherapeutic clinical trials, a sign the research field is catching up on data specific to women.

Northwestern researcher Francesca Duncan, PhD, has described the ovary as a "canary in the coal mine" for understanding aging elsewhere in the body, a framing that captures why this gap matters.

What ovarian aging can tell you about the rest of your body

A 2013 study on biomarkers of ovarian reserve found associations between reproductive aging markers and broader somatic aging processes, suggesting the ovaries may not age in isolation from the rest of the body.^† Large population studies have also linked earlier menopause to shorter lifespan, which is part of why some researchers now view the age of menopause itself as a longevity signal worth tracking, not just a reproductive milestone.

Supporting ovarian and hormonal health during your reproductive years

Always consult your healthcare provider before starting any new supplement, especially if you are trying to conceive, currently pregnant, or breastfeeding.

You cannot reverse ovarian aging, but you can support the hormonal signaling and cycle regularity that matter during your reproductive years. Myo Chiro 40:1, formulated to support healthy hormone signaling and ovarian health, uses a clinically studied 40:1 ratio of Myo-Inositol to D-Chiro-Inositol.† Many women layer this with our fertility gummies with methylated folate and myo-inositol, which include 13 fertility-focused nutrients formulated to support reproductive wellness while trying to conceive.† Neither Myo Chiro 40:1 nor Premium Fertility Gummies is intended for use during pregnancy.

Both formulas are third-party tested, made in cGMP-certified facilities, and Myo Chiro 40:1 includes Berry ScentCert to help with day-to-day taste comfort. Premium Fertility Gummies were developed with guidance from Pink Stork's OBGYN-Led Advisory Board.

"Every stage of a woman's body tells a story, and I believe understanding that story, backed by real science, is one of the most empowering things we can do for ourselves and each other."

What to actually do with this information

If you are in your late 20s to early 40s and thinking about your reproductive timeline, ovarian reserve testing is a conversation to have with your provider, not a number to chase on your own. It is one data point among many, not a verdict. Pairing that conversation with daily habits that support hormone signaling and cycle regularity is something you can start now, regardless of when or whether you plan to conceive.

Frequently asked questions

Is a low AMH level the same as infertility?

No. AMH reflects the size of your remaining egg reserve, but it does not measure egg quality, and it is not a definitive predictor of your ability to conceive.

Can I improve my ovarian reserve?

Current evidence does not support reversing ovarian reserve decline. Nutritional and hormone-signaling support can be part of a broader preconception routine, alongside guidance from your provider.†

At what age should I ask about ovarian reserve testing?

There is no single universal age. Many women bring it up when they start thinking seriously about family planning, or if they have a family history of early menopause.

Is Myo Chiro 40:1 safe during pregnancy?

No. Myo Chiro 40:1 is not for use during pregnancy. Always consult your healthcare provider before starting any new supplement.

Why is ovarian aging relevant to longevity, not just fertility?

Emerging research links reproductive aging markers, including age at menopause, to broader patterns of biological aging, which is why some researchers now study the ovaries as part of whole-body healthspan, not a separate system.

What does the 40:1 ratio in Myo Chiro 40:1 refer to?

It refers to the 2,000 mg of Myo-Inositol to 50 mg of D-Chiro-Inositol ratio used in the formula, a ratio that has been clinically studied for hormonal and ovarian health support.†
