If you’re trying to conceive and researching fertility, you may have come across the term FSH — follicle-stimulating hormone. But what is FSH, and why does it matter when you’re trying to get pregnant?
In this post, we’ll explain what FSH is, what a normal FSH level to get pregnant looks like, and what your results may mean for your fertility journey.
What Is FSH?
FSH (follicle-stimulating hormone) is a hormone produced by the pituitary gland that plays a critical role in a woman’s reproductive cycle. It helps stimulate the growth of ovarian follicles, which house your eggs.
In short, FSH prepares your body for ovulation — and understanding your FSH level can give important clues about your ovarian reserve (the quantity and quality of your remaining eggs).
What Is a Normal FSH Level to Get Pregnant?
FSH levels are measured with a simple blood test, usually done on day 3 of your menstrual cycle. This is commonly called a day 3 FSH test and is one of the first tests doctors use when assessing fertility.
Here are general guidelines for FSH levels and what they might mean:
| FSH Level (mIU/mL) | What It May Indicate |
|---|---|
| Under 10 | Normal / Good ovarian reserve |
| 10–15 | Borderline / Possibly reduced reserve |
| 15–20 | Reduced ovarian reserve |
| Over 20 | Poor ovarian reserve |
⚠️ Note: FSH ranges can vary slightly depending on the lab, your age, and your overall hormonal balance.
Why FSH Levels Matter for Fertility
When FSH is high, it typically means your brain is working harder to stimulate your ovaries which may suggest a lower egg count or diminished ovarian reserve. This can make it more difficult to conceive naturally.
When FSH is too low, it might signal a problem with the brain’s signaling to the ovaries (such as hypothalamic dysfunction) which could also impact ovulation.
How FSH Is Tested
- When to test: Day 3 of your menstrual cycle
- How it’s measured: Blood test
- What else may be tested: Estradiol (E2), LH (luteinizing hormone), and AMH (anti-Müllerian hormone) for a fuller picture
What to Do If Your FSH Level Is High or Low
If your FSH level is not within the “optimal” range, it’s important not to panic. Many women with elevated or borderline FSH levels still conceive either naturally or with the help of fertility treatments.
Your next steps might include:
- Repeating the test: Hormone levels can vary from month to month
- Testing other fertility hormones, such as AMH and estradiol
- Consulting a fertility specialist for personalized guidance
- Exploring fertility treatments like IUI or IVF, if needed
Key Takeaway: FSH Is Just One Piece of the Puzzle
While your FSH level can offer valuable insight into your fertility, it’s not the only factor. Age, AMH, lifestyle, uterine health, and your partner’s fertility all contribute to your chances of getting pregnant.
