FSH Ovarian Reserve Checker
Enter your age and basal (day-3) FSH level to see what it suggests about your ovarian reserve.
FSH Result
FSH varies cycle to cycle and should be read with AMH, AFC, and age. Not a diagnosis — consult a specialist.
About FSH and fertility
Follicle-stimulating hormone (FSH) is measured on day 2-3 of the cycle. Higher FSH often signals lower ovarian reserve.
One FSH value is not the whole picture — AMH and antral follicle count (AFC) give a fuller view.

FSH calculator FAQ
What's a normal FSH level?
A basal (day-3) FSH under about 8–10 mIU/mL is generally reassuring.
Does high FSH mean low fertility?
It may suggest reduced ovarian reserve; combine with AMH and AFC.
How do FSH and AMH differ?
AMH reflects reserve steadily; FSH varies cycle to cycle — both help together.
