Varicoceles: effect on testicular volume in prepubertal and pubertal males.

A total of 63 prepubertal and 17 pubertal males were examined to determine both testicular volumes and to correlate testicular volumes with the presence or absence of a varicocele. In the prepubertal group neither the left nor the right testicle predominated in size. In the pubertal group, the left testicle with an associated varicocele was smaller than the right.
