Abstract
We investigated the relationship between seminal plasma nitric oxide (NO) concentrations and conventional semen parameters in patients with varicocele. Semen samples were obtained from infertile patients with varicocele (n=55) and from normal controls (n=48). The mean NO concentration in the seminal plasma of patients with varicocele was significantly higher than that of the controls (P < 0.01). A significant negative correlation was noted between NO and sperm motility (r=−0.29, P=0.003), NO and sperm concentration (r=−0.26, P=0.008) and NO and normal morphology (normal %) (r=−0.25, P=0.01). It was concluded that increased NO production may influence sperm production, motility and morphology in patients with varicocele.
