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.
