Testicular parameters and morphological characteristics of testicular and epididymal spermatozoa of white Fulani bulls were study using twenty testicles. The objective was to study the normal testicular parameter and morphological changes during epididymal transit in the epididymis of white Fulani bulls. It was observed that there was reduction in the proportion of spermatozoa carrying the proximal cytoplasmic droplet (PCD) along the epididymis as spermatozoa mature. There were more narrow head in the left (0.40) than the right epididymis (0.10). There was more bent normal tail (16.7) in the left epididymis than in right epididymis (13.0). The sperm cells having looped tails are higher in the left epididymis (caput, 4.90; corpus, 5.30; caudal 4.30) than the right epididymis (caput, 4.70; corpus, 3.20; caudal 5.10) despite the fact that the caudal epididymis in the right epididymis has a higher mean value. In this study the left testicle had more of the morphologically defective spermatozoa (12.96%) than the right testicles (12.42%). The epididymal and testicular parameters were positively correlated (weight of epididymis, weight of estis and epididymis, length of epididymis, circumference of the testes and epididymis, (p<0.05)
