What should I know about zu wenig progesteron symptome?

The question about low progesterone symptoms is clinically relevant, but the provided context contains no information about progesterone or its symptoms. Generally, low progesterone can cause menstrual irregularities, PMS, sleep disturbances, mood swings, and in pregnancy an increased risk of miscarriage. However, evidence for standalone progesterone testing in otherwise healthy individuals is weak; many symptoms are non-specific. Without medical evaluation and lab testing, self-diagnosis is not advisable. The genetic tests mentioned in the context (e.g., lactose intolerance) are unrelated to progesterone. Therefore, the evidence level for this question is 'unclear'.
