الأسئلة الشائعة

Which cycle day should FSH be measured on?

Days 2 to 5, counting from the first day of your period. Outside that window the reference ranges above do not apply. If you no longer menstruate, the day does not matter.

Is FSH the same as AMH?

No, they are different hormones providing complementary information. FSH rises as ovarian reserve decreases; AMH drops. AMH can also be measured on any cycle day, FSH cannot.

Do I need to fast for an FSH test?

No, fasting is not needed. The cycle day matters far more than whether you have eaten.

What is FSH on a blood test?

FSH stands for follicle-stimulating hormone and is made by your pituitary, a small gland at the base of the brain. On your lab form it appears as the abbreviation, with a result in IU/L. It is almost always measured together with LH and oestradiol. Those three only mean something alongside each other. Fasting is not required. The cycle day is: if you still menstruate, days 2 to 5 are the right window.

What does a high FSH mean?

A high FSH means your pituitary is pushing harder because your ovaries are responding less. On a day 3 measurement, 10 to 15 IU/L fits a declining ovarian reserve. Above 15 IU/L fits reduced ovarian function. Above 25 IU/L fits perimenopause. In men a high result points to reduced sperm production. A single raised result is never enough to establish anything. That is truest in perimenopause, when the hormone swings sharply month to month.

How high does FSH go in menopause?

After menopause the reference range is 25.8 to 134.8 IU/L. That is roughly ten times the follicular-phase range. In perimenopause a day 3 value above 25 IU/L fits. Above 40 IU/L, with twelve months without a period, fits menopause. Over the age of 45 the measurement is not recommended for diagnosing menopause. That is exactly when the hormone fluctuates most.

Which blood values point to menopause?

The combination of a high FSH and a low oestradiol fits menopause. That means a value above roughly 25 to 40 IU/L. The oestradiol sits below the premenopausal range. In practice no single blood value makes the diagnosis. Dutch GP guidance works from your symptom pattern and the course of your periods. Blood testing mainly adds something if you are younger than 45 and your periods have stopped.
