Myths vs facts: AMH and sleep

The question about myths vs facts regarding AMH and sleep cannot be answered from the provided context, which contains no relevant information. Generally, AMH (anti-Müllerian hormone) is a marker of ovarian reserve and is primarily influenced by age, genetics, and conditions like PCOS. Some mechanistic hypotheses suggest that chronic sleep deprivation might affect ovarian function via cortisol and melatonin, but evidence is weak and mostly from animal or small observational studies. No large human trials demonstrate a direct causal effect of sleep on AMH levels. AMH also fluctuates during the menstrual cycle. Therefore, claims that improving sleep significantly raises AMH are currently myths without strong evidence. Sleep is important for overall health, but using AMH as a standalone fertility or sleep quality marker is not supported by robust data. Consumers should be cautious of marketing that overstates this link.
