Ovarian reserve reflects the quantity of remaining eggs. Three tests are commonly used together: AMH (anti-Müllerian hormone — most reliable, can be drawn any cycle day), FSH (day 2–3 of cycle), and AFC (antral follicle count on transvaginal ultrasound). No single test tells the whole story.

Important: AMH predicts ovarian response to stimulation, not natural pregnancy potential directly. A low AMH at any age does not mean pregnancy is impossible — it means fewer eggs may be retrieved in an IVF cycle. This tool is for educational interpretation, not clinical diagnosis.

Hormone Test Results
Most reliable ovarian reserve marker. Can be drawn any day of the cycle.
ng/mL
If your result is in pmol/L, divide by 7.14 to convert to ng/mL
Day 2 or 3 of menstrual cycle. Higher FSH = less ovarian reserve.

Ultrasound
Total number of small resting follicles (2–10 mm) counted in both ovaries on transvaginal ultrasound, typically cycle day 2–5.

Ovarian Reserve Assessment
AMH and natural fertility: Per ACOG Committee Opinion 773, AMH should not be used to counsel women on their natural fertility outside of formal fertility treatment. A low AMH does not preclude spontaneous conception. These results are best discussed with a reproductive endocrinologist or your gynecologist in the context of your full clinical picture.
