# What does a high AMH mean?

> High AMH means many small follicles are active in the ovaries — most often PCOS, where AMH is typically two to three times higher than average for age. A high AMH in someone without PCOS features can simply mean an above-average egg reserve, which is favorable for fertility treatment but also raises the risk of over-response to stimulation. Rarely, granulosa cell tumors raise it markedly.


## What is the normal range for AMH?

- Female, age 18–35: 1.00 – 6.80 ng/mL
- Female, age 36–45: 0.300 – 4.00 ng/mL
- Female, age 46+: 0.000 – 1.50 ng/mL

Can reflect PCOS or, in some contexts, certain ovarian conditions.

## What are the common causes of high AMH?

1. Polycystic ovary syndrome
2. High ovarian reserve (normal variation, especially under 30)
3. Recent stop of hormonal contraception (rebound)
4. Granulosa cell ovarian tumors (rare)

## What symptoms go with high AMH?

- Irregular or absent periods, acne, excess hair if PCOS
- Often none

## What do clinicians usually check next?

- LH, FSH, testosterone and DHEA-S; pelvic ultrasound for PCOS evaluation
- Fasting insulin/A1c — insulin resistance commonly accompanies PCOS
- For fertility treatment, share the value with the clinic to tailor stimulation

## Common questions

### Does a high AMH mean I'm very fertile?

It means a large egg supply, which is not the same as egg quality or regular ovulation. With PCOS, high AMH often coexists with irregular ovulation.
