Fertility is closely linked to a woman’s ovarian reserve, and one of the most important indicators of this reserve is the AMH (Anti-Müllerian Hormone). Understanding AMH levels and egg count is essential for women planning pregnancy naturally or through IVF.
This guide explains AMH, egg reserve, and how fertility changes with age.
What is AMH?
AMH (Anti-Müllerian Hormone) is a hormone produced by small follicles in the ovaries. These follicles contain immature eggs.
AMH helps doctors understand:
- How many eggs are left in the ovaries
- A woman’s fertility potential
- Response to IVF treatment
- Ovarian aging
AMH is measured through a simple blood test and can be done on any day of the menstrual cycle.
Why is AMH Important in IVF?
AMH plays a critical role in IVF because it helps doctors:
- Predict how ovaries will respond to stimulation
- Estimate the number of eggs that can be retrieved
- Plan personalized IVF protocols
- Improve IVF success chances
Higher AMH generally means better ovarian reserve, but pregnancy is still possible with low AMH.
How Many Eggs Does a Woman Have?
Unlike men, women are born with all the eggs they will ever have.
Here is the approximate egg count at different ages:
| Age | Egg Count |
| Before birth | 60–70 lakh |
| At birth | 10–20 lakh |
| Puberty | 3–4 lakh |
| Age 25 | 1.5–2 lakh |
| Age 30 | 1–1.5 lakh |
| Age 35 | 50,000 |
| Age 40 | 10,000–20,000 |
| Menopause | Less than 1,000 |
Egg count and quality decline naturally with age.
What is Normal AMH Level by Age?
| AMH Level | Meaning |
| Above 3.0 ng/ml | High (Good reserve) |
| 1.5 – 3.0 ng/ml | Normal |
| 1.0 – 1.5 ng/ml | Low Normal |
| Below 1.0 ng/ml | Low |
| Below 0.5 ng/ml | Very Low |
AMH and Fertility: Important Facts
- AMH does not measure egg quality, only quantity
- Women with low AMH can still conceive
- High AMH is common in PCOS
- AMH declines naturally with age
- IVF success depends on multiple factors, not AMH alone
What Causes Low AMH?
Common causes include:
- Age
- Genetics
- Ovarian surgery
- PCOS
- Chemotherapy
- Smoking
- Poor lifestyle
Can AMH Be Improved?
AMH cannot be significantly increased, but fertility health can be supported by:
- Healthy diet
- Regular exercise
- Stress management
- Avoid smoking
- Fertility supplements (as advised by doctor)
Conclusion
AMH is one of the most important indicators of ovarian reserve and plays a key role in fertility and IVF planning. Every woman is born with a fixed number of eggs, and this reserve declines with age.
Early fertility testing helps women make informed reproductive decisions and improves IVF planning.
