Is TSH useful for Fruchtbarkeit?

TSH (thyroid-stimulating hormone) is a useful marker for thyroid function and can be relevant for fertility. Both hypothyroidism and hyperthyroidism can disrupt menstrual cycles, ovulation, and implantation. However, TSH alone is not a sufficient predictor of fertility. Clinical practice suggests that TSH levels above 2.5 mIU/L in women trying to conceive may be associated with increased miscarriage risk, but the evidence is primarily observational. A normal TSH does not rule out other fertility issues. The value of a single TSH measurement is limited; it should be interpreted alongside fT3, fT4, anti-TPO antibodies, and clinical symptoms. Comprehensive fertility assessment requires additional hormonal and functional tests. MyBody-X tests include TSH as part of metabolism analysis, but no validated fertility-specific claims are provided in the given context. Therefore, TSH is useful but not definitive for fertility evaluation.
