Home / Calculators / Fertility assessment / Antral follicle count
Every calculator in one place, free and with no sign-up. Results show instantly — we don't hide them behind a form. Each one explains what the number means, where the reference ranges come from, and what it cannot tell you.
A calculator sees three or four figures. A specialist sees your history, your scans, your partner's results, and how you actually responded to treatment. If you're between cycles, changing clinics, or something in your results doesn't add up, a second opinion is the fastest way to find out whether anything would be done differently.
Free first consultation. No obligation to start treatment, and it doesn't affect your care at your current clinic.
These tools provide general information and are not a diagnosis or a substitute for assessment by a qualified clinician. Reference ranges and sources are stated on each calculator. Predictive estimates describe groups of people and cannot predict an individual outcome.

What your AFC suggests about likely response to stimulation.
Compared to published rangesYour values checked against published reference limits. The source is named below; laboratory methods vary.
Antral follicle count is the number of small follicles visible on ultrasound early in the cycle, and predicts response to stimulation. Counts under 5 often meet criteria for poor response; 9 to 20 is associated with a normal response.
Source — AFC is operator-dependent and varies with ultrasound equipment and technique. Ranges are indicative and awaiting local calibration.
The bands on this page are drawn from published sources but have not yet been reviewed by our medical team, and some vary by laboratory or assay. Check against the reference range printed on your own report.
Both ovaries combined
That falls in the 9–20 band.
Your result of 12 follicles sits in the highlighted band. Bands are reference points used alongside clinical findings — not a diagnosis.
Within the range associated with a normal response to stimulation.

Highlighted is the stage this measurement belongs to. It is a map of the process, not a schedule — timings vary by protocol and by clinic.
Yes. AFC is counted early in the cycle, typically day 2 to 5. A count taken later will be misleading.
It is operator- and equipment-dependent, and there is genuine biological variation between cycles. A single count is a guide rather than a fixed number.
Yes, by a few follicles in either direction — that is normal biological variation rather than a change in your reserve. What matters is the broad range your counts sit in, not any single scan. If two counts differ wildly, ask whether they were done on the same cycle day and by the same operator.

AFC is operator-dependent and interpreted alongside AMH and age. Nothing here is a diagnosis or a substitute for assessment by a clinician.
A calculator gives you a number. These explain what it means, and what it does not.
