Why this test

FSH is the primary signal your brain sends to your ovaries or testes — and elevated levels can indicate diminishing reserve.

Follicle-stimulating hormone (FSH) is released by the pituitary gland. In women, it stimulates egg development and is a key marker of ovarian reserve — rising FSH levels may indicate perimenopause or diminished ovarian reserve. In men, elevated FSH may reflect reduced testicular function. FSH is often tested alongside LH, oestradiol, and AMH for a complete fertility or menopause assessment.

Understanding your results

Within reference range

Interpretation is cycle-phase and sex-dependent — discuss with your healthcare practitioner in context

Normal reproductive range

FSH in this range is typical during the follicular phase — interpretation depends on cycle timing

Below reference range

Low FSH may suggest pituitary or hypothalamic involvement — discuss with your healthcare practitioner

Elevated

Consistently elevated FSH (especially >10 IU/L on day 2–5) may indicate reduced ovarian reserve or testicular function — worth discussing with your healthcare practitioner

Reference ranges vary by laboratory and personal context. Your result is shown against the lab's range in your dashboard, alongside what it means.

For ovarian reserve or fertility assessment, day 2–5 of your cycle (counting the first day of your period as day 1) is standard. Your healthcare practitioner may request testing at a specific cycle point.

FSH naturally rises during and after menopause. Outside of that context, consistently elevated early-cycle FSH may warrant further fertility investigation — but a single result should always be interpreted alongside your full clinical picture.

No fasting is required.

For ovarian reserve assessment, annually if planning conception after 35. For perimenopause or menopause monitoring, as symptoms change or as directed by your healthcare practitioner.
