Mikhael NV, et al. - Researchers evaluated the seminal plasma granulysin level in infertile patients with varicocele. They included 90 men that were allocated into fertile normozoospermic men, infertile men without varicocele and infertile men with varicocele. Findings suggested a negative impact of increased seminal granulysin on spermatogenesis in infertile men in general and in infertile men associated with varicocele in particular. They noted a negative association of seminal granulysin level with sperm concentration, sperm motility, sperm normal forms percentage and testicular volumes.
