Needle biopsy of testes: a safe outpatient procedure

A total of 287 testes biopsies were performed in the office under local anesthesia, using a modified needle and technique to collect the tissue which was then fixed in Bouin's solution. Adequate tissue was obtained in all specimens for histopathologic diagnosis. In 3 patients small hematomas developed and were treated conservatively. Five patients complained of orchialgia, but none required narcotic analgesia. No sperm antibodies, extravasation, or serious complications were encountered. We believe this technique is safe, simple, and cost-effective.
