What is a normal AMH level?
AMH level is barely detectable in the new-born baby. However, it slowly increases after a few weeks. The level peaks at around 25 years of age in women. The standard levels of AMH test varies between 2 to 4 in young women. It decreases with age and becomes very low for around 40 years.
In women with the poor ovarian capacity, it may be less than 1ng/ml. In PCOS women AMH test is significantly high. It may vary between 4 to 20ng/ml. A high AMH test indicates possible hyperstimulation in IVF treatment.
When should the AMH test be done?
AMH levels fail to follow the endocrine fluctuations that are so typical for the menstrual cycle. In the human ovary, AMH is mainly produced by granulosa cells of small antral follicles sized 2–6 mm. within the normal menstrual cycle, the variability of AMH levels is extremely small. Therefore, a single measurement of AMH obtained at any time in the menstrual cycle may be considered a valid reflection of a woman’s ovarian reserve.
| Age | AMH Level |
| New born Baby girl | Very low |
| After few weeks | Mild increase |
| At around 25 yrs | Highest level |
| 31- 35yrs | Maintains or slightly decreases |
| 35- 40 yrs | Moderate decrease |
| More than 40 yrs |
Low |
What factors can change the value of the AMH test?
- PCOS
- Ovarian surgery
- Cancer treatment
- Oral contraception
- Obesity
- Breast Cancer risk
- Vitamin D deficiency
- Serum AMH levels can also be affected by environmental and genetic factors
Can you improve your AMH level?
AMH test is an indicator of ovarian reserve. Smoking, body mass index [BMI], use of alcohol can change the level of AMH. Adopting a healthy lifestyle may bring changes in ovarian efficiency. Dietary changes and exercise help to reduce weight and body mass. Similarly, quitting smoking and alcohol intake may help in some cases.
