[A morphological and morphometric study of the testicle in the rat vasectomized by electrocautery technics].
OBJECTIVE
To evaluate the influence of vasectomy by different fulguration methods on the rat testicular structure.


METHODS
Experimental vasectomy was performed in Wistar rats by means of the Shapiro and Silber, and the Schmidt cauterization techniques. The animals were orchidectomized between 7 days and 9 months following vasectomy. A morphological and morphometric study of the rat testes was performed.


RESULTS
We have observed that both cauterization techniques do not produce sequelae in the rat testicular structure and its morphology is compatible with the normal. The morphometric study showed that both techniques produced a significant decrease (p > 0.05) of the area occupied by seminiferous epithelium within one month post-vasectomy; however, these values returned to normal three months thereafter.


CONCLUSIONS
Vasectomy by different fulguration methods does not change the rat testicular structure.
