Ovarian Reserve / AMH Calculator

Anti-Mullerian hormone (AMH) is a protein produced by granulosa cells in ovarian follicles. AMH levels reflect the quantity, though not the quality, of remaining eggs (ovarian reserve). Higher AMH generally indicates more eggs remaining; lower AMH suggests diminished ovarian reserve. AMH is used by fertility specialists to predict response to ovarian stimulation for IVF and to counsel patients on fertility timeline. Levels naturally decline with age. Consult a reproductive endocrinologist for clinical interpretation.

AMH reference ranges vary slightly between labs, but general patterns are: ages 25 to 34, approximately 1.5 to 4.0 ng/mL; ages 35 to 39, approximately 1.0 to 3.0 ng/mL; ages 40 to 44, approximately 0.5 to 2.0 ng/mL; age 45 and above, below 1.0 ng/mL. Values below the low end for your age bracket may indicate diminished ovarian reserve. These are population averages, and a single AMH result should not be used alone to make fertility decisions.

A low AMH indicates reduced egg quantity but does not predict the quality of remaining eggs or the ability to conceive naturally. Some women with low AMH conceive without intervention, while others with normal AMH struggle due to egg quality or other factors. Low AMH is most significant in predicting response to fertility medications during IVF. If you have concerns about your ovarian reserve, consult a board-certified reproductive endocrinologist for a comprehensive fertility evaluation.

The antral follicle count (AFC) is the number of small follicles visible on transvaginal ultrasound at the start of a menstrual cycle. Like AMH, AFC reflects ovarian reserve quantity. AFC and AMH tend to correlate well and are often used together for a more complete picture. An AFC of 6 to 10 per ovary is generally considered normal, with lower counts indicating diminished reserve. Both tests are typically ordered together during an initial fertility evaluation.
