title: [Effects of vasectomy on the testicular structure of the dog].
abstract: Study of the effect on testis structure in the dog caused by a vasectomy. Emphasis is made on how in animals undergoing ligature of both ends of the ductus deferens, existence of structural changes, which are consistently present, are proportional to the time elapsed from performance of vasectomy. Such changes are revealed by: degeneration of germinal epithelium, thickening of basal membrane and hypertrophy of interstitial tissue at the expense of unspecific connective tissue. Changes were first seen as from the fourth month, but a full year has to elapse prior to noting a marked germinal hypoplasia. These experimental results cast doubts on the safety of such sterilization approach, although they cannot be entirely extrapolated to humans.
