Present study deals with results of fine needle aspiration of both the testes in a patient with azoospermia. Surprisingly, aspiration of right testis revealed large number of microfilariae in the smears. Conversely, left testicular aspirate showed few spermatogonia. However, microfilariae were not detected in venous blood smears. Findings of this study suggested possible role of Wuchereriabancrofti in causation of azoospermia.
