Abstract:
Objective To investigate the effects of high spermatic vessel dissection on testicular morphological alteration of SD rats in prepuberty,puberty and sexual maturity phases.Methods Thirty-day-old SD rats were divided into 2 groups underwent sham operation and left high spermatic vessel dissection as a simulation of Palomo′s maneuver.Detailed morphological investigations were made at 3 different postoperative intervals among the 3rd day,30th day and 56th day.Results High spermatic vessel dissection in prepubertal rats induced acute testicular ischemia in the operated testes on the 3rd day.Most of the operated testes on the 30th day showed testicular atrophy.And all the operated testes showed testicular atrophy and sperm disappearance in epididymis on the 56th day.Conclusion High dissection of spermatic vessel in prepubertal rats induced testicular ischemia in prepuberty and testicular growth failure in puberty,testicular atrophy completely and sperm production losing in sexual maturity phase.
