Objective: To establish ultrasound guided testicular fine needle aspiration (TFNA) as well as to assess the effectiveness of uni-directional (UD) and multi-directional (MD) TFNA in buck according to testicular cells, echotexture and gross changes of testicle, age of buck was considered. Methods: A total of 120 samples were collected with both directions (UD, n=60) and (MD, n=60) suction from testis of 10 apparently healthy bucks. All slides were stained with May-Grünwald-Giemsa and examined under light microscope with 1 000 × magnifications to count spermatogenic cells, spermatozoa and sertoli cells. The percentage of spermatozoa and sertoli cells were expressed as spermatic index and sertoli cell index. Results: Results revealed no difference in the presence of various spermatogenic and sertoli cells in cell cluster of slides made either unidirectional TFNA or multidirectional TFNA. Early spermatids were the most numerous, followed by late spermatids, primary spermatocytes, spermatogonia. Sertoli cell index was higher in TFNA smears of young bucks prepared 7-13 mo of age and spermatic index was higher in adult bucks 14-24 mo of age. No echogenic change was observed in the echotexture of testisafter TFNA. Conclusions: It seems that TFNA has no serious ill effect on the buck testis when uni-direction aspiration is performed. Moreover, the possibility to standardize this method might provide a greater impulse to the clinical diagnostics of male animal infertility.
