When is AMH test recommended for diminished ovarian reserve?

Anti-Müllerian hormone is produced by developing ovarian follicles. A blood result gives an estimate of the remaining follicle pool, so it can support discussion of diminished ovarian reserve or help anticipate response to ovarian stimulation. It does not measure egg quality, confirm whether pregnancy will occur, or by itself diagnose infertility. Results need context because hormone levels vary with age, some medicines, and ovarian conditions.

A fertility clinician may suggest AMH testing when conception has been difficult, ovarian surgery or treatment may have affected reserve, periods suggest a hormonal concern, or treatment planning requires an estimate of follicle response. Ask whether you need preparation and whether other tests, such as antral follicle count or assessment of ovulation and the fallopian tubes, are relevant. Use the result as one part of a plan rather than a prediction on its own.

Arrange a fertility assessment if you have been trying to conceive without success, have very irregular or absent periods, or have a history that may affect ovarian function. Seek prompt care for sudden severe pelvic pain, heavy bleeding, or symptoms after fertility medication. A clinician can decide whether AMH is appropriate and interpret it with your symptoms and examination.

Ask what decision the AMH test is intended to inform, how the result will change your options, and which companion tests are needed. Ask how your age, medicines, cycle pattern, and fertility plans affect interpretation, and when you should review the results.
