Introduction: Understanding AMH and Fertility
Anti-Müllerian Hormone (AMH) is often considered a key indicator of a woman’s ovarian reserve — the number of eggs remaining in the ovaries. Many women believe that having high AMH levels automatically means high fertility. However, doctors clarify that while AMH reflects egg quantity, it does not always guarantee successful conception.
So why can someone with high AMH still struggle to get pregnant? Experts explain several possible reasons.
What Does High AMH Mean?
AMH is produced by small follicles in the ovaries. Higher AMH levels generally indicate:
- A higher number of available eggs
- Good ovarian reserve
- Strong response to fertility treatments
However, AMH does not measure egg quality, ovulation regularity, or overall reproductive health.
1. Polycystic Ovary Syndrome (PCOS)
One of the most common causes of high AMH is PCOS.
Women with PCOS often have:
- Irregular ovulation
- Hormonal imbalance
- Multiple small follicles in the ovaries
Even though AMH levels are high, ovulation may not occur regularly, making conception difficult.
2. Poor egg Quality
While AMH reflects the number of eggs, it does not indicate their quality. egg quality naturally declines with age, especially after 35. Poor-quality eggs may:
- Fail to fertilize
- Lead to early miscarriage
- Result in unsuccessful implantation
3. Ovulation Disorders
Some women with high AMH may still experience:
- Irregular ovulation
- Anovulation (absence of ovulation)
- Delayed ovulation
Without consistent ovulation, pregnancy cannot occur naturally.
4. Thyroid or Hormonal Imbalances
Hormones play a crucial role in conception. Even with high AMH, conditions such as:
- Thyroid disorders
- Elevated prolactin levels
- Insulin resistance
can interfere with ovulation and fertility.
5. Blocked Fallopian Tubes
Even if ovulation occurs and egg reserve is good, blocked or damaged fallopian tubes can prevent the egg and sperm from meeting.
Common causes include:
- Pelvic infections
- Endometriosis
- Previous surgeries
6. Male Factor Infertility
Doctors emphasize that fertility is not solely dependent on women. In many cases, difficulty conceiving may be due to:
- Low sperm count
- Poor sperm motility
- Abnormal sperm morphology
A complete fertility evaluation of both partners is essential.
7. Endometriosis
Endometriosis can impact implantation and egg quality, even if AMH levels are high. It may cause inflammation and scarring that interferes with conception.
When Should You See a Doctor?
You should consult a fertility specialist if:
- You are under 35 and trying for more than 1 year
- You are over 35 and trying for more than 6 months
- You have irregular cycles or known hormonal issues
Early diagnosis improves treatment outcomes.
Conclusion: AMH Is Only One Piece of the Puzzle
Having high AMH is generally a positive sign regarding ovarian reserve, but it does not guarantee pregnancy. Fertility depends on multiple factors — egg quality, ovulation, hormonal balance, uterine health, and male factors.
Doctors recommend a comprehensive fertility assessment rather than relying solely on AMH levels. With proper diagnosis and timely treatment, many couples can successfully conceive.
