[Morphofunctional evaluation of the testes in cryptorchism].

In both abdominal and inguinal cryptorchism, complex morphological changes are observed with age in the undescended testis. Significant changes in the size of the seminiferous tubules are observed morphometrically; the most informative index was the surface of the tubuli and their relative volume in the total volume of the organ. The main importance in the development of cryptorchism belongs, in the authors' view, to the hormonal disturbance of the anterior lobe of hypophysis and Leydig cells which are practically absent in the undescended tests in fetuses, newborns and children of the first year of life with multiple congenital developmental abnormalities.
