What does diminished ovarian reserve mean in women over 40?

Ovarian reserve refers to the remaining supply of eggs, not simply whether you are ovulating this month. A person can have regular periods and still have a lower reserve. After 40, both the number of available eggs and the chance that an egg is chromosomally suitable for pregnancy may be affected by age. Reserve testing cannot predict exactly when menopause will occur, and it does not measure egg quality directly.

Clinicians may assess reserve with an anti-Müllerian hormone (AMH) blood test, follicle-stimulating hormone (FSH) testing at a particular point in the menstrual cycle, and an ultrasound that counts antral follicles. Results can vary, and they need to be interpreted with menstrual history, ultrasound findings, previous pregnancies or fertility treatment, and your goals. A low result is a reason to discuss options promptly, not a diagnosis of infertility.

If you want to become pregnant, arrange an appointment with a fertility specialist or gynaecologist rather than waiting for several months of trying. Ask which tests are appropriate and whether your partner should have a semen analysis at the same time. Depending on your results and preferences, the discussion may include trying naturally, ovulation monitoring, assisted conception, egg freezing for future use, or donor eggs. The suitable choice depends on your overall health, fertility history, timeline, and local clinical advice.

Bring the dates and patterns of your periods, a list of medicines and supplements, prior pelvic surgery or ovarian treatment, and any earlier fertility results. Avoid starting hormone treatment or supplements marketed to improve egg reserve without professional advice; they cannot restore the number of eggs remaining.

Seek fertility advice soon if you are over 40 and want a pregnancy, particularly if periods have become irregular, you have had ovarian surgery, or you have received chemotherapy or radiation. Make a routine appointment if testing has shown a low reserve so the result can be reviewed in context and a time-sensitive plan considered.

Get urgent medical help for sudden severe pelvic pain, fainting, shoulder-tip pain, or heavy vaginal bleeding. These symptoms need assessment for causes that cannot be diagnosed from an ovarian-reserve result alone.

Ask: Which result suggests diminished reserve in my case? Does the test need repeating or timing within my cycle? How do my age, ultrasound, ovulation pattern, and partner’s results change the plan? What options fit my timeline, and how quickly should I decide?
