Spermatic granulomas of ischemic origin in the rat epididymis.
The sequelae of the permanently reduced blood flow through the testes of rats, in which stenosis of the abdominal aorta had been produced by inserting an incomplete ligature between the two renal arteries, were studied. In a high proportion of animals, spermatic granulomas occurred unilaterally or bilaterally in the epididymides. Their development was proceded by an ischemic injury; the contents of the canaliculi penetrated into the interstitium, producing a marked macrophagic reaction, which developed after the 5th day. Simultaneously, ischemic lesions were observed in the testes.
