CLINICAL STUDY OF THE SPERMATOGENESIS OF UNDESCENDED TESTICLES

This paper is based on a study of a group of patients with either unilateral or bilateral undescended testicles observed at the Children's Hospital, from 1900 to 1934. During this period 665 cases of cryptorchidism were observed in this clinic. Unfortunately, 186 of the patients have disappeared so that all efforts to reach them over a three year period have failed. Of the remaining 479, 336 have been located, interviewed and examined. Larger series than this have been reported from other clinics, but so far as can be determined all of the investigators have judged the excellence of their end-results on the position and size of the testicle at periods varying from two months to several years after operation. These investigations have been valuable for comparing the various methods of orchiopexy to place and hold the testicle in the scrotum. However, the prime interest in these cases should be centered
