Follicle Stimulating Hormone (FSH)

Measure your FSH levels with a simple finger-prick test from home to assess ovarian function, fertility potential, and hormonal health.

🩸 What Is FSH and Why Does It Matter?

Follicle Stimulating Hormone (FSH) is a key reproductive hormone produced by the pituitary gland. In women, FSH regulates the menstrual cycle and supports the growth of ovarian follicles—small sacs containing immature eggs.

The amount of FSH in your blood varies depending on your age and menstrual cycle phase. Measuring your FSH level can help assess:

• Ovarian reserve (the quantity of eggs remaining)
• Fertility potential
• Menopausal status
• Hormonal imbalances
• Conditions such as PCOS or premature ovarian insufficiency

📈 What Does the FSH Test Show?

This test measures the concentration of follicle stimulating hormone in your blood. Your result can offer vital insights:

• High FSH levels may suggest:
  • Menopause or perimenopause
  • Poor ovarian reserve (lower egg supply)
  • Premature ovarian failure
  • Resistance to ovarian stimulation
• Low FSH levels may indicate:
  • Hypothalamic or pituitary dysfunction
  • Stress-related amenorrhoea
  • Polycystic ovary syndrome (PCOS)

Your FSH level is typically evaluated in relation to your menstrual cycle and in combination with other hormones such as LH, oestradiol, and AMH for a more complete fertility profile.

🎯 Who Should Take This Test?

You should consider testing your FSH levels if you are:

• Trying to conceive (especially after 6–12 months)
• Over 35 and assessing fertility or ovarian reserve
• Experiencing irregular or absent periods
• Having symptoms of early menopause (hot flashes, night sweats, low libido)
• Diagnosed with or suspecting PCOS or hormonal imbalance
• Starting or monitoring IVF or fertility treatment

🕒 When to Take the FSH Test

The best time to measure FSH is between day 2 and day 5 of your menstrual cycle (with day 1 being the first day of your period). Testing at this point provides the most accurate reflection of baseline ovarian function.

If you are no longer menstruating or have irregular cycles, the test can still be taken—our lab will interpret your result accordingly.

📊 What’s Included in Your Results

• Your FSH level (with units and reference ranges)
• Clear explanation of what your level may indicate
• Doctor-reviewed interpretation based on your cycle phase and age
• Guidance on next steps (e.g., fertility options, GP referral, or lifestyle changes)

💡 What Can High or Low FSH Levels Mean?

🔺 High FSH

High levels on day 3 of your cycle may mean the body is trying harder to stimulate the ovaries—often a sign of declining egg supply or menopause. It may also indicate:

• Early ovarian ageing
• Reduced success rates in IVF
• Primary ovarian insufficiency (POI)

🔻 Low FSH

Low FSH could indicate a hormonal disruption in the brain-pituitary-ovary communication system. Possible causes include:

• PCOS
• Hypothalamic amenorrhoea (often from stress or low body weight)
• Pituitary gland disorders

🤔 Frequently Asked Questions

Q: Is this test suitable for women of all ages?
A: Yes, though it is most useful for women of reproductive age and those approaching menopause.

Q: Can I take this test while on the pill?
A: Hormonal contraceptives may suppress natural FSH production. It’s best to take this test after stopping hormonal birth control for more accurate readings.

Q: Will this test tell me if I’m fertile?
A: While FSH gives a good indication of ovarian reserve, fertility involves many factors. It’s best used alongside other hormone tests and clinical advice.
