title: Seminal characteristics in the presence of a varicocele as compared with those of expectant fathers and prevasectomy men.
abstract: One hundred and thirty-one semen analyses were performed on men found to have a varicocele on a routine physical examination. The seminal characteristics of these men were contrasted with those of 87 men who were desirous of having a vasectomy and with those of 25 expectant fathers. No significant differences were found in the mean sperm density in these three groups of men. However, it was noted that a greater percentage of men with a varicocele had a sperm count of 20 million or less as compared with the control groups. It was also found that a greater percentage of the men with either a large or medium-sized varicocele had a sperm count of 20 million or less than those with a small varicocele. There was no significant difference in the percentage of oval forms, motility, or tapered forms in the three groups of men with a varicocele as compared with expectant fathers and men desirous of a vasectomy.
