What do studies say about TSH Frauen?

The provided context does not contain studies on TSH in women. Therefore, I cannot derive an evidence-based answer from the given material. In general medical knowledge, TSH reference ranges differ in women (e.g., lower during pregnancy) and are influenced by iodine status, thyroid autoimmunity, and age. However, without specific sources from the context, the evidence level is unclear. Medical evaluation is always recommended for abnormal TSH.
