Fertility in undescended testes.
Since 1956 many children with undescended testes have been treated at the Red Cross War Memorial Children's Hospital in Cape Town, and in this article the conesequent degree of fertility achieved by orchidopexy, the method of treatment, is appraised. In 567 children the condition was unilateral, and in 202 it was bilateral. Assessment of potential fertility in 76 unilateral and in 29 bilateral cases was mainly by semen analysis; the average age of the youths at the time of the examination was 19 years, and parenthood was therefore regarded as an unsuitable criterion for assessment. Four hundred and ninety-two youths had their condition reviewed, and the condition of 587 testes was assessed. The anatomical state of the testes was ascertained to help in the assessment, but also, and of greater importance, to obtain evidence of the usefulness of orchidopexy for cosmetic or psychological benefit. Biopsy of the affected testes, carried out in some, proved to be nor more informative than the anatomical appraisal, with regard to spermatogenesis. Two useful facts emerged from the study. About 10% of bilateral undescended testes are capable of normal spermatogenesis after orchidopexy, and 65% are sterile, while the fertility of persons with unilateral undescended testis is impaired, 28% having little hope of paternity, and 4% no hope at all.
