RESUMO
Cryptorchidism is more often diagnosed and treated in pediatric age. Its occurrence in adult provides oppotunity to study its spontaneous course. This study has been realized on one series of 81 flies of patients cryptorchides of age superior than 14 years. Cryptorchidism was unilateral in 87.6% of cases and bilateral in 12.4% of cases. The higher the location, the more important the glandular atrophy and histological lesions.Global rate of secretory azoospermia was 93% in relation with a seminiferous disertion and an intersitial fibrosis. The lesions are important when cryptorchidism is bilateral. In two patients there was a progression to malignancy. Occasional cases of return to normal semen after orchidopexy have been reported, and that should preclude systematic orchidectomy advocated by some. Orchidopexy remain a treatment of choice even in adults
