FSH Follicle Stimulating Hormone
Also Known As
Test Parameters Included
- Serum FSH Level:
- FSH operates on a feedback loop with the ovaries (in women) and testes (in men).
- When these organs are not producing enough hormones (like estrogen or inhibin), the brain releases more FSH to try and jumpstart them.
- Therefore, a high FSH level often indicates that the ovaries or testes are struggling to function.

Frequently Asked Questions
Why should I test FSH on Day 2 or 3 of my period?
This is when your ovaries are at rest. Testing at this time provides a "baseline" that shows how hard your brain has to work to wake up your ovaries.
Does a high FSH mean I can't get pregnant?
Not necessarily, but it suggests that your ovarian reserve may be low. It is a signal to consult a fertility specialist for a more detailed evaluation.
Why does the report take 6 hours?
Our automated systems prioritize accuracy and efficiency, allowing for a thorough quality-checked result within the same day.
Can stress affect my FSH levels?
Yes. Severe physical or emotional stress can interfere with the brain's signaling to the reproductive organs, leading to abnormal results.
Does FSH change with age?
Yes. As women approach menopause, FSH levels naturally rise because the ovaries become less responsive to the hormone.
Can I take this test while on the pill?
You can, but the result will likely be very low. Birth control pills suppress FSH, so the test won't reflect your natural hormonal status.
Why is FSH tested in men?
It helps determine if a low sperm count is caused by a problem in the testicles or a signaling problem in the brain.
Can I drink water before the test?
Yes, plain water is fine.
What is the difference between FSH and LH?
FSH stimulates the growth of the egg follicle, while LH triggers the release of the egg (ovulation).
What if my FSH is normal but I'm still not conceiving?
Fertility is complex. You may still need to check egg quality (age), fallopian tube health, or male factor fertility.
Does Biotin really matter?
Yes! Biotin can make FSH levels look much lower than they actually are on the lab machine. Always stop it 3 days prior.
Is FSH used for PCOS?
Yes. In PCOS, the LH level is often much higher than the FSH level (a high LH:FSH ratio).
Is this test the same as the "Egg Timer" test?
No, the "Egg Timer" test usually refers to AMH, but FSH is a critical second piece of that puzzle.
Does smoking affect FSH?
Yes. Smoking is toxic to the ovaries and can lead to an earlier rise in FSH and an earlier onset of menopause.
Is the test result confidential?
Absolutely. At Dr. Patho Labs & Diagnostics, all reproductive health data is protected by strict privacy protocols.
