| Ten healthy male (boar) of large white pigs aged between 6.0 and 18.0 months, were used for this study. Spermiogram and morphological characteristics were studied in testes and in the different parts of the epididymis of the boar. The objective was to study the changes that occur in testes and epididymis during epididymal transit. Progressive motile spermatozoa were first observed in the testes (6-10%) in the caput (20-30%), corpus (40-50%) and highest at the caudal epididymis (85%). Cytoplasmic droplets were lost as the spermatozoa moved up the epididymis. The caput epididymis had a value of 20.05% of abnormal sperm cell, which is different significantly (p<0.5) from 15 80 % of the caudal epididymis. The total abnormal sperm cells in corpus are also... |

| The morphological characteristics and haematological studies were studied in fifteen male albino rats (Wistar Strain) aged between 12 and 14 weeks and with a body weight of 150- 180g. The rats were allowed to feed on commercially prepared rat pellet and provided with fresh water ad libitum. The rats were divided into three groups; the rats were in groups A, B and C of 5 rats each. Group A served as control of the study; Group B was treated with Chloramphenicol at the dose rate of 25mg/kg body weight per os for 20 days; while Group C was treated for 25 days. Semen used in this study was obtained from the caudal epididymides while morphological aberrations were determined from spermatozoa counted after stained with Wells and Awa stain. Results of the... |

| 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... |
