ABSTRACT
<p><b>OBJECTIVE</b>To investigate the Toxoplasma gondii (TOX) infection in males with sterility and the effect of the infection on the reproductive function of males.</p><p><b>METHODS</b>Enzyme linked immunoabsorbent assay (ELISA) was used to detect TOX-CAg, TOX-IgG and TOX-IgM in the peripheral blood of male patients with sterility.</p><p><b>RESULTS</b>Among 100 cases of male sterility, 7 were TOX-IgG positive (7%), 16 TOX-IgM positive (16%) and 13 TOX-CAg positive (13%). Among 100 normal males, 7 were TOX-IgG positive (7%), 3 TOX-IgM positive (3%) and 1 TOX-CAg positive (1%).</p><p><b>CONCLUSION</b>TOX infection may affect the fertility of males and cause male sterility. For this reason, males should prevent themselves from TOX infection.</p>
