Can TSH Schilddrüse help with Fruchtbarkeit?

TSH (thyroid-stimulating hormone) is a key marker of thyroid function. Both hypothyroidism and hyperthyroidism can impair fertility by disrupting menstrual cycles, ovulation, and egg quality. However, a single TSH test is insufficient to assess fertility. Clinical guidelines recommend a full thyroid panel (TSH, fT3, fT4, and antibodies) when trying to conceive. A normal TSH (0.5–2.5 mU/L) is favorable, but even subclinical changes may matter. A home blood test can provide a preliminary indication but does not replace medical evaluation. The evidence for TSH testing in fertility is strong (clinical practice), but interpretation requires an endocrinologist or gynecologist. Caveat: TSH fluctuates diurnally and can be affected by stress, medications, or illness.
