THE EFFECT OF BLOCKING VAS DEFERENS ON SPERMATOGENESIS

The effect of blocking vas deferens on structural changes in testes was studied. The study found out that the blocking of vas deferens after 30 days from the start of the experiment caused the development of histological and ultrastructural changes in testes of animals, which were expressed in a decreased diameter of the convoluted seminiferous tubes and volume of nuclei of the interstitial endocrine cells. It also lead to deformation of ultrastructures of the blood-testis barrier elements with a marked decrease in the number of developing germ cells, including sperm cells.
