Testicular function after orchiopexy.
Twelve adult mongrel dogs underwent unilateral division of the spermatic vessels and contralateral testicular revascularization to compare the effect of these techniques on histology of the testes. Testicular weight reduced to average 6.5 Gm (normal 20 +/- 5 Gm) where division of the vessels was performed. The contralateral side maintained its weight and configuration (average weight 22.5 Gm). Histologic changes occurred in nonrevascularized testes indicating atrophy and hence inadequate blood perfusion for testicular survival. Sperm density was reduced, but only vas deferens draining the revascularized testis contained spermatozoa.
