Can TSH Schilddrüse help with fertility?

TSH (thyroid-stimulating hormone) is a key regulator of thyroid function. Thyroid dysfunction (hypo- or hyperthyroidism) can impair fertility by disrupting menstrual cycles, ovulation, and sperm quality. Measuring TSH is therefore an important part of fertility workup. However, TSH alone is not a magic bullet; it must be interpreted alongside free T3, T4, antibodies, and clinical symptoms. The evidence linking thyroid function to fertility is moderate to strong, based on numerous clinical studies. Caution: a normal TSH does not rule out thyroid involvement, and treatment should only be given for confirmed dysfunction. Direct-to-consumer tests can be misleading without medical interpretation. In summary, TSH can be a useful marker but not a standalone solution for fertility issues.
