What to watch with TSH Schilddrüse and Fruchtbarkeit?

The question about TSH, thyroid, and fertility is clinically important, but the provided context (MyBody-X DNA tests for weight, metabolism, pharmacogenetics) contains no direct information on TSH or thyroid parameters. TSH is a blood biomarker reflecting thyroid function – a key factor for fertility, as both hypo- and hyperthyroidism can affect menstrual cycles and implantation. According to the context, MyBody-X offers DNA, blood, microbiome, and intolerance tests, but DNA tests do not measure hormone levels. A blood test for TSH, fT3, fT4, and thyroid antibodies is standard for fertility workup. Evidence for a direct link between genetic variants (e.g., in TSHR or DIO2) and fertility is weak and not covered here. Caution is warranted: do not rely solely on DNA tests; have your thyroid evaluated by a physician if you are planning pregnancy. Evidence: unclear, as no relevant sources are present in the context.
