What is a normal follicle-stimulating hormone (FSH) level for IVF?


Follicle-stimulating hormone (FSH) is an important hormone made in your pituitary gland. The FSH test checks if your pituitary gland produces too much or too little FSH, or if you have any potential issues with your ovaries or testicles.

For women, FSH levels naturally fluctuate throughout the menstrual cycle, so the test is normally undertaken around day 3 of the cycle.

In general, the normal result for women between the first day of the period and ovulation is between 1.4 and 9.9 IU/mL. For men, the normal results are between 1.4 and 15.5 IU/mL.

The FSH test is usually done in combination with anti-müllerian hormone (AMH) and antral follicle count (AFC) tests because normal FSH on its own cannot accurately predict whether your ovaries will produce suitable eggs in response to stimulation.
