Cryptorchism.

Our results from 121 patients as well as data from the literature prove that fertility rates after treatment of uni- or bilateral cryptorchism remain unsatisfactory. There is no statistically significant difference in fertility between a group of patients treated with human-chorionic-gonadotrophin and another group treated by orchidopexy after unsuccessful hormonal therapy. On the other hand, late results in unilateral cryptorchism are to a statistically significant extent better than in bilateral cryptorchism (46/29%). According to our histological findings in maldescended testicles, early treatment (before the age of 3 years) is advocated.
