Etiopathogenesis of cryptorchidism and male infertility.

A retrospective study was performed 2.60 +/- 1.14 years after ochidopexy on 124 patients with cryptorchidism. Complex spermatological, hormonal, and histomorphological investigations were carried out which demonstrated the existence of disturbances in the exo- and endocrine functions of the testes of these patients. The results juxtaposed to the ages when the orchidopexy was accomplished revealed the necessity of early surgical intervention prior to 5 years of age. After this age there were severe changes in the histomorphological characteristics of the testicular tissue.
