정관절제수술이 흰쥐 고환의 미세구조에 미치는 영향

The fine structure of the rat was studied at intervals of up to ten month after bilateral vasectomy. Controls were bilaterally sham operated. Objective was to determine whether the fine structure of the testis is altered as a result of vasectomy. Attention was directed toward the ultrastructure of seminiferous epithelium. Focal alterations in the restricted region were detected, but this fact didn't prove the effect of vasectomy on the testis. Sperm granulomas developed in all the vasectomized rats. Factors are discussed whicch may qualify this conclusion, the structural complexity of developing germ cells, the multiplicity of stages in the cyclle of the seminiferous epithelium, and development of sperm granulomas.
