What is FSH?
FSH is a signalling hormone produced in the brain that helps regulate reproductive hormone activity. 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 well your body coordinates communication between the brain and reproductive organs. 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: 2–10 IU/L
- Post-menopausal women: 20 IU/L or higher
- Men: 1.5–12.5 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.
