Does elevated thyroid-stimulating hormone (TSH) affect men who are preparing for pregnancy?

In general, elevated thyroid-stimulating hormone (TSH) levels may affect men who are preparing for pregnancy. The detailed analysis is as follows:

Thyroid-stimulating hormone (TSH) is a hormone secreted by the pituitary gland and plays a regulatory role in thyroid function. Elevated TSH levels typically indicate hypothyroidism, although they may also be associated with other diseases or medication use. Hypothyroidism may impair sperm quality, including sperm count, motility, and morphology, potentially reducing fertility and decreasing the chances of conception. Additionally, thyroid hormones interact with other hormonal systems, such as sex hormones and pituitary hormones. Hypothyroidism may disrupt hormonal balance, thereby affecting the normal function of the reproductive system. Moreover, hypothyroidism may also impact male libido and sexual function, including reduced sex drive and erectile dysfunction. Therefore, elevated TSH levels can negatively affect men who are trying to conceive.

Hence, during preconception planning, if a man has elevated TSH levels, it is recommended to consult a physician or an endocrinology specialist to obtain professional advice and guidance.
