Identification of Spermatozoa in Archived Testicular Cancer Specimens: Implications for Bench Side Sperm Retrieval at Orchiectomy

The data suggest that sperm retrieval at the time of radical orchiectomy is a feasible fertility option, with a 40% probability of recovering spermatozoa by random biopsy of the noncancerous testicular parenchyma and an 80% probability of recovering spermatozoa with a more extensive dissection. In 50% men, spermatozoa may be recovered by epididymal aspiration alone.
