AMH and ovarian reserve testing in Green Park

Anti-Müllerian hormone is produced by small growing follicles in the ovaries. Clinicians use it mainly as an ovarian-reserve marker and to help anticipate response if ovarian stimulation is planned.

AMH does not count every remaining egg, directly measure egg quality or reliably predict natural conception on its own. Results also need the laboratory's units and reference range; comparing numbers from different laboratories without context can be misleading.

An antral follicle count, or AFC, is measured by ultrasound and counts visible small follicles at that point in the cycle. It gives the clinician a second view of ovarian reserve and may reveal information about the ovaries or uterus that a blood test cannot.

AMH and AFC do not always align perfectly. A doctor can interpret a mismatch in the context of age, contraception, recent ovarian surgery, endometriosis, cycle pattern and the reason you were tested.

AMH can generally be measured on most days of the menstrual cycle, while an AFC is often scheduled early in the cycle for consistent interpretation. Your care team may adjust timing based on your medicines or clinical situation.

Tell the team about hormonal contraception, pregnancy or recent fertility treatment and bring older AMH or scan reports if you want to understand a trend. A single change does not automatically show rapid decline; laboratory and biological variation also matter.

For someone planning pregnancy, an ovarian-reserve result is only one part of the picture. For egg freezing or IVF, it may help shape medication and counselling about likely egg yield. For irregular cycles or possible PCOS, a higher AMH may require a different interpretation.

The useful question is not simply whether a result is 'normal'. Ask what it changes for your timeline, whether another test would add value and when—if at all—it should be repeated.
