Sexual development in patients treated for cryptorchidism.

An analysis of sexual development was carried out in adult patients treated in childhood for cryptorchidism. Forty-seven healthy men served as a control group. The cryptorchid patients had been treated between the ages of 10 months to 13 years and their ages ranged from 16 to 30 years at follow-up. The onset of puberty, and sexual development, were within normal limits in all patients, although spermarche occurred somewhat later in the patients than in the controls. In addition, the patients were on average slightly less sexually active than the controls. Neither age at the time of treatment nor the method of treatment correlated with current sexual activity. The patients with larger testes were, however, sexually more active. Both treatment age and the method of treatment, whether hormonal or surgical, should be selected on the basis of fertility prognosis.
