Anatomy of the testis and epididymis in cryptorchidism.

The types and incidence of deformities in the proximal seminal pathways have been carefully studied in 150 consecutive orchidopexies. 85% of the testicles were found in the subcutaneous tissue, 15% were in the canal or the abdomen. Malunion between the testis and the epididymis was the type of anomaly most frequently encountered. Deformities considered to affect fertility were seen in 70% of the gonads located proximal to the external inguinal ring and in 12% of the subcutaneous testicles. The difference is statistically significant.
