Abstract

Cryptorchidism is a condition in which one or both testicles lies outside the scrotum (Scorrer, 1964; Hoesli, 1971). According to Knorr (1970), cryptorchidism is the most common endocrine gland disturbance. 2.7 % of all mature newborns are cryptorchid, while the percentage of cryptorchids among premature infants is as high as 31 %. (Scorrer and Farrington, 1971). The undescended testicle is or becomes permanently damaged as a result of its situation, so that 60–85 % of all unilateral cryptorchids are subfertile or sterile (Hansen, 1945; Michelson, 1952; Bayle, 1957; Carver, 1958; Seguy, 1961; Guillon and Seguy, 1964; Hellinga, 1964; Nicole and Spindler, 1964). In the case of bilateral cryptorchids, 91–100 % are subfertile or sterile (Hansen, 1945; Michelson, 1952; Raboch and Zachor, 1955; Mack, 1960; Scott, 1961 ; Doepfmer and Nienaber, 1964; Nicole and Spindler, 1964).
