AFC & Egg Retrieval Estimator
Enter your age and antral follicle count (AFC) to estimate likely ovarian response and egg yield in an IVF cycle.
Estimated Ovarian Response
AFC is one indicator of ovarian reserve. Actual egg yield varies with stimulation protocol and individual response. This is an estimate, not a prediction.
About AFC and ovarian reserve
The antral follicle count (AFC) is the number of small follicles visible on ultrasound at the start of a cycle. It reflects your ovarian reserve and helps predict IVF response.
AFC naturally declines with age. A low AFC does not mean zero chance — it means the approach may need adjusting.
FertiJourney's specialists personalize stimulation based on your AFC and AMH — get a free IVF assessment.
AFC calculator FAQ
What's a normal antral follicle count?
Roughly 5–15 per ovary is typical; it declines with age.
Does a low AFC mean IVF won't work?
Not necessarily — it predicts fewer eggs, but a tailored protocol can still succeed.
How is AFC measured?
By counting small follicles on an early-cycle transvaginal ultrasound.
