Abstract
The study was undertaken to investigate the seasonal variation occurring in some parts of male reproductive system (tests and epididymis) of local rams during seasons of year. A total of 167 samples from rams aged 8-12 months were collected from local slaughter house for one year. The aim of this study of followed the seasonal changes and their effecting on the activity of reproductive system, weight and dimensions of testis and epididymis. The results showed increased significantly during autumn to weight , volume , length , width and thickness of testis to reached 146.70 gm , 138.04 cm3 , 75.61 mm , 52.63 mm and 54.06 mm respectively, compare with other seasons. Caput of epididymis increased significantly during the autumn to reach (100 mm) length , (16.92 mm) width and (17.47 gm) weight where as the length reached lowest during winter (85.77 mm), width and weight (14.83 mm) , (5.40 gm) respectively during the spring. The investigated showed the corpus of epididymis reached highest length during the autumn (57.31 mm) and lowest length during the summer (37.61 mm), while the width of corpus reached highest during the spring (7.59 mm) and lowest during the summer (5.94 mm) , and the corpus showed lowest weight during summer (0.76 gm) compare with other seasons.
