title: [Peculiarities and side effects of testicular biopsy].
abstract: Testicular biopsies were performed in hospital conditions on 451 patients by whom was diagnosed oligozoospermia (56,5%), azoospermia (41,9%), teratozoospermia (1,2%) and aspermia (0,4%). 95,5% of these biopsies were bilateral. Anatomic peculiarities as well as particularities and complications observed during the operations, and lastly postoperative complications were demonstrated in this contingent of patients. In order to obtain this result the clinical documents of the department of andrology of the university hospital Hamburg-Eppendorf were used. Adhesions of the tunical layers of the testis (28,3%), as well as hydroceles (35,7%), and increased vascularisation (20,9%) could be seen in the operation field. We considered as the most frequent intraoperative step a second skin cut (4,6%). In 3,0% of the cases it was not possible to obtain a testicular parenchyma. As complication during the operation the sliding of the epididymis was observed in 4,8%, and bleeding in 2,0% of the cases. The most frequent complication after operation was bleeding in the region of the skin's suture (1,2%). Patients who presented intraoperative complications bleeded most. Orchitis and epididymitis as postoperative complications were not observed. To prevent these complications the testicular biopsies should be done in hospital conditions by well experienced operation teams.
