Myths vs facts: AMH and stress

The question of myths vs. facts regarding AMH and stress cannot be directly answered from the provided context, as it contains no specific information on AMH or stress. In general, AMH (anti-Müllerian hormone) is a well-established marker of ovarian reserve, primarily influenced by age. The myth that acute or chronic stress drastically lowers AMH levels is not well supported by scientific evidence. While stress hormones like cortisol can affect the hypothalamic-pituitary-gonadal axis and indirectly impair ovarian function, direct, consistent effects on AMH have not been clearly demonstrated in studies. Some cross-sectional studies show weak inverse associations, while others find no link. The fact is: AMH is relatively stable across the menstrual cycle and is mainly determined by genetics and age. Stress may impair fertility through other pathways (e.g., cycle disturbances) but not via a significant AMH reduction. The evidence base is therefore unclear; prospective studies with standardized stress measures are needed. Consumers should not rely on AMH as a 'stress indicator' and should seek medical advice for fertility concerns.
