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 mo of age and spermatic index was higher in adult bucks 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.
