title: [Value of intensive thyroid assessment in male infertility].
abstract: In infertile men thyroid hormone and antibody testing was performed and correlated with the results of semen analyses. Evaluation included semen analyses, physical examination, evaluation of sex steroid hormones, thyroid hormones (bTSH, fT4, fT3) and thyroid antibody testing (TGA, TPO-Ab, TRAK). Furthermore 45 men with normal thyroid function were scheduled for TRH testing. No one was diagnosed as having manifest hypo- or hyperthyroidism. Latent thyroid dysfunction had no effect on semen parameters. Elevated TPO-Ab were significantly correlated with reduction in motility of spermatozoa. The routine assessment of thyroid hormones and antibodies in infertile men is not recommended. Subclinical hypothyroidism as a result of TRH testing is a rare finding in infertile men.
