How is diminished ovarian reserve different in women over 40?

Ovarian reserve describes the remaining egg supply, not egg quality alone. With age, the number of available eggs generally declines, and tests may show a lower anti-Müllerian hormone level, a lower antral follicle count, or a change in follicle-stimulating hormone. These results help estimate how the ovaries may respond to fertility medication. They do not confirm whether natural conception will or will not occur, and a regular cycle does not rule out reduced reserve.

If pregnancy is a goal, arrange a fertility discussion without unnecessary delay. A clinician may review cycle history, ovarian reserve tests, semen analysis, ovulation, the fallopian tubes, and other health factors. Ask how quickly results are available and which options fit your goals, including trying naturally, fertility treatment, or preserving eggs when appropriate. Avoid interpreting one result without the wider assessment.

Book an appointment if you are over 40 and want to become pregnant, if cycles become irregular, or if you have a history of ovarian surgery, chemotherapy, endometriosis, or early menopause in the family. Seek prompt medical advice for severe pelvic pain, heavy bleeding, or a positive pregnancy test with one-sided pain or dizziness.

Ask which reserve tests are suitable, how your results affect treatment choices, whether age-related egg quality is also a concern, and what timeframe you recommend for trying or seeking fertility treatment. Ask when results should be repeated and which symptoms need urgent review.
