Your Egg Reserve Counter
AMH is produced by small ovarian follicles—the more you have, the higher your AMH. It's the best blood test for estimating remaining egg supply (ovarian reserve). Unlike FSH, it's stable throughout the cycle and declines steadily with age. Important: AMH measures quantity, not quality.
What is AMH (Anti-Mullerian Hormone)?
AMH is produced by granulosa cells of preantral and small antral follicles. Stable throughout the cycle (test any day). Correlates with antral follicle count on ultrasound. Undetectable at menopause. Not affected by hormonal birth control.
↑ What High AMH (Anti-Mullerian Hormone) Means
Large follicle pool. Reassuring for fertility but also a hallmark of PCOS (many small follicles, none ovulating properly).
Common symptoms:
In PCOS context: irregular periods, acne, hirsutism · Otherwise asymptomatic
↓ What Low AMH (Anti-Mullerian Hormone) Means
Fewer follicles remaining. Doesn't mean you can't conceive, but suggests a narrowing fertility window and may affect IVF response.
Common symptoms:
No direct symptoms from AMH itself · Shorter cycles as menopause nears · Difficulty conceiving · Poor IVF response
Why It Matters
When normal:
Best blood marker of ovarian reserve
Cycle-independent (any day)
Predicts IVF response
Helps diagnose PCOS
Estimates time to menopause
Risks if abnormal:
Low: diminished reserve, reduced IVF response
Does NOT indicate egg quality
Very high: PCOS likely
What Can Cause Abnormal Levels?
Age-Related Decline (low)
60% likelyAMH declines naturally. Rate varies individually and is partly genetic.
PCOS (high)
55% likelyExcess small follicles produce excess AMH. >4-5 ng/mL is diagnostic.
Ovarian Surgery
Removing ovarian tissue directly reduces AMH.
Chemotherapy
Gonadotoxic treatment destroys follicles.
Smoking
Accelerates follicle loss.
What You Can Do
AMH reflects reserve and cannot be meaningfully increased
Impact: Focus on egg quality rather than quantity \u00B7 Timeline: N/A
Quit smoking (if applicable)
Impact: Stops accelerated follicle loss \u00B7 Timeline: Immediate
If lifestyle changes aren't enough:
CoQ10: 200-600mg daily
Impact: Supports egg quality (mitochondrial function) \u00B7 Timeline: 3-6 months
DHEA: 25mg 3x daily (under fertility specialist guidance)
Impact: May improve ovarian response in IVF \u00B7 Timeline: 2-4 months
Recommended retest: Annually for fertility tracking
