FSH blood test: normal range and what your result means

FSH, or follicle-stimulating hormone, is made by the pituitary gland in your brain, and it tells the ovaries to ripen an egg each cycle. As the ovaries wind down towards menopause, the brain sends more FSH to get a response, so a rising FSH is one sign of perimenopause, though it can swing month to month. It's usually tested on day 2 to 5 of your cycle, when the lab range is 3.4 to 21.6 IU/L, and after menopause it sits at 20 IU/L or higher. FSH is in the Female Hormone Health, Perimenopause and Menopause Hormone Tests, $299 each, with no Medicare rebate.

What is FSH?

FSH is a signalling hormone produced in the brain that helps regulate reproductive hormone activity and is measured through an FSH hormone blood test. It plays a role in maintaining hormonal balance, energy regulation, and overall vitality.

Why does it matter for long-term health and wellbeing?

FSH reflects how effectively your body coordinates communication between the brain and reproductive organs and is assessed through a lab test FSH. Balanced levels support steadier energy, healthier ageing, and a clearer picture of your hormonal rhythm over time.

What’s an optimal level of FSH?

Typical Australian laboratory reference ranges include:

  • Menstruating women: 2 to 10 IU/L
  • Post-menopausal women: 20 IU/L or higher
  • Men: 1.5 to 12.5 IU/L

Optimal ranges sit toward the midpoint of these bands, depending on age and life stage.

What influences FSH levels?

FSH can shift with age, stress, energy balance, nutrition, sleep, and natural hormonal fluctuations. It may also vary due to lifestyle choices and changes across the reproductive lifespan.

What does it mean if FSH is outside the optimal range?

FSH levels above or below your expected range may indicate that your body is adapting to internal or external pressures. It’s a useful prompt to review factors such as stress load, recovery, and daily routines, and to discuss your results with a healthcare professional if needed.

How can I support healthy FSH levels?

Balanced nutrition, consistent sleep, stress management, movement, and supporting overall metabolic health can help maintain healthy hormonal rhythms. Tracking your levels over time makes it easier to understand patterns and refine your habits.

How does your FSH compare with Vively members like you?

Among Vively members, median FSH was 6.2 IU/L in women still having periods, 11.0 IU/L in women in perimenopause and 65.4 IU/L after menopause. In men, the median was 4.0 to 6.0 IU/L in every age band. Compare yourself with your own group only. The groups are very different.

Check your FSH against your group

Choose your group, then type your result. Nothing you type is stored or sent.

These are Vively members who chose to add a hormone test, so they may not represent all Australians. Women are grouped by the menopause stage they told us. Women who were unsure of their stage are not shown. Cycle day, the pill, HRT and testosterone treatment are not recorded with these results. A member median is not a target or a normal range.

Source: first FSH result per member, January 2024 to October 2026 (1,420 members). Each group has at least 50 members. See also our guide to oestradiol and FSH levels by age and menopause stage.
