Sperm count and sperm motility in incidental high-grade varicocele

One hundred twenty-four otherwise healthy men with suspected high-grade varicocele, comprised of 28 patients with grade 2 and 96 with grade 3 varicocele, were referred to us by their primary care providers to determine their exact grade so that they could be exempted from the compulsory armed force service if they had grade 3 varicocele. In the grade 2 and grade 3 groups, mean sperm concentration and mean sperm motility were 80.89 million per milliliter (SD, 38.98 million/mL; median, 74.5 million/mL; range, 22-210 million/mL) and 78.77 million per milliliter (SD, 41.34 million/mL; median, 77 million/mL; range, 0-223 million/mL) and 58.39% (SD, 13.7%; median, 60%; range, 22-75%) and 60.31% (SD, 16.93%; median 65%; range, 0-80%), respectively, with no statistically significant differences between the two groups, no patient with infertility as a complaint during a 20-month period, and no patient with sperm concentrations of <20 million/mL, but with six patients with sperm motilities <50%. In summary, by far the great majority of patients with high grade varicocele have more than normal sperm output. Higher grades of varicocele are not associated with more pronounced deleterious effects on sperm concentration and percentage motility. Incidentally diagnosed high-grade varicocele is not a progressive condition, and almost all patients retain normal semen quality, at least over a period of 20 months.
