Abstract

Vasectomy was performed on 63 rats at age 81 to 105 days. Examination 28 to 58 days later disclosed no significant reductions in testis size with respect to preoperative testis length and to testis length and weight in unoperated controls. The fact that the minimal atrophy observed was primarily left-sided sugested that these effects were artifacts of the procedure or systemic left-right differences in the animals.
