Can AMH Levels Fluctuate During the Menstrual Cycle?

Unlike other reproductive hormones, AMH levels remain relatively stable throughout the menstrual cycle. This makes AMH testing more reliable and convenient than other markers like FSH, which fluctuate significantly. However, slight variations may occur due to individual differences, lab techniques, or external factors like stress or recent hormonal treatments. In rare cases, women with irregular cycles or underlying conditions may experience subtle AMH changes. Because of its stability, the AMH test can be performed on any day of the cycle, providing a consistent indicator of ovarian reserve without timing constraints.
