A new approach in evaluation of fertility in surgically treated cryptorchids.

In this study twenty two operated cryptorchids were followed up (average period 12.02 years) and various indices of function like size, semen analysis and histology were assessed. FNAC as an index of spermatogenic potential of testis was added and compared with other investigations. The fertility potential in operated unilateral cryptorchids was 86.7 percent and in bilateral 42.9 percent. As an investigation in cryptorchids, FNAC correlated well with semen analysis and histology in all respects--the two gold standards. When done in a child FNAC would hence give an excellent idea of spermatogenic potential of that testis, regardless of age. We recommend that FNAC being the least traumatic but equally reliable modality should replace biopsy in the intraoperative as well as subsequent follow up evaluation of cryptorchids.
