Abstract
During the years 1976–1988, 412 patients were operated upon for cryptorchid testes. In 28 unilateral and 2 bilateral cryptorchid patients, no testes could be found. Pathologic examination of the blind-ended vas deferns (usually a nodule) in 6 cases showed calcified or hemosiderin-containing tissue. In 9 patients an abundance of blood vessels was noted. In 27 patients signs of fibrosis and/or hyalinization were found. It is postulated that in most instances the vanishing testis syndrome is due to in-utero vascular occlusion of the testicular vessels, which is most likely caused by torsion of the testis.
