[Function of the hematotesticular barrier and of developing germ cells in short-term ischemia of the testes].
In the experiments performed in 32 mature white male rats by means of light and electron microscopy, sensitivity of developing germ cells to the effect of an acute testicular ischemia during 3, 5, 10, 15, 30 min has been studied. The first structural changes in the convoluted seminiferous canaliculi appear after the ischemia lasting for 3-5 min. Certain destructive changes in the hematotesticular barrier elements and in the germ cells are resulted from the ischemia lasting for 15-30 min. The most sensitive cells are spermatocytes at the pachynema stage and spermatids, their number is decreasing.
