NO levels in the seminal plasma of patients in each group were measured and compared. In infertile men with varicocele, semen parameters, including sperm count and motility, and grade of varicocele were also determined. <strong></strong></span></span></span></p><p class="MsoNormal" style="margin: 0cm 0cm 0pt; direction: ltr; unicode-bidi: embed; text-align: justify;"><span style="font-size: small;"><span style="font-family: Times New Roman;"><strong><span style="mso-bidi-language: FA; mso-bidi-font-family: 'B Yagut';">Results: </span></strong><span style="mso-bidi-language: FA; mso-bidi-font-family: 'B Yagut';">Mean NO concentrations were 52.34 </span><span style="mso-bidi-language: FA;">± </span><span style="mso-bidi-language: FA; mso-bidi-font-family: 'B Yagut';">26.62 </span><span style="mso-bidi-language: FA;">µ</span><span style="mso-bidi-language: FA; mso-bidi-font-family: 'B Yagut';">mol/L, 37.06 </span><span style="mso-bidi-language: FA;">± </span><span style="mso-bidi-language: FA; mso-bidi-font-family: 'B Yagut';">20.39 </span><span style="mso-bidi-language: FA;">µ</span><span style="mso-bidi-language: FA; mso-bidi-font-family: 'B Yagut';">mol/L, and 33.7 </span><span style="mso-bidi-language: FA;">± </span><span style="mso-bidi-language: FA; mso-bidi-font-family: 'B Yagut';">18.99 </span><span style="mso-bidi-language: FA;">µ</span><span style="mso-bidi-language: FA; mso-bidi-font-family: 'B Yagut';">mol/L in groups 1, 2, 3, respectively.
