FSH is an abbreviation for “Follicle Stimulating Hormone”. FSH tells us about the egg reserve in the ovaries.

The lower the FSH value is, the more eggs are left. Normal FSH values are between 3 and 10 IU/l.

FSH values fluctuate during the cycle. Therefore they must be analysed on the womans 2nd or 3rd day of menstruation. FSH is also dependent on the blood levels of Oestradiol. Therefore it is important to have Oestradiol measured simultaneously.

If the woman is 40 or older and her FSH is above 10 IU/l, it is not sure we can offer treatment.
