Testicular volume and testicular atrophy index as predictors of functionality of unilaterally cryptorchid testis

The goal of this study was to determine relationship between the sensitivity and specificity of testicular volume (TV) and testicular atrophy index (TAI) in the indirect assessment of functional ability of cryptorchid testicles. The study included sixty children with unilateral cryptorchidism who were treated surgically at the Clinic of Pediatric Surgery, Clinical Center University of Sarajevo. We evaluated the correlation of the size of cryptorchid testicles with its locations in various age groups. The results showed a significant decrease in TV and TAI in the all cryptorchid groups after the sixth month of age compared with the same parameters in control group (p < 0.001). It is also determined a strong correlation between the TV and TAI of cryptorchid testicles with its locations in various age groups. Our results showed that the average volume of cryptorchid testicles decreased after the sixth month as well as that the reduction of testicular size correlated with increasing distance of cryptorchid testicles from the scrotum.
