Semen production depends upon different factors as age, breed, collecting and environmental conditions. The present research has in view to establish the influence of age upon the quantitative and qualitative parameters of semen from few of the Romanian buffalo reproducers. There were analyzed 12 native buffalo males, from different age category. At every semen collecting there were recorded the following morphologic sperm parameters: sperm volume, sperm concentration(x 109spz/ml), colour, mass activity, pH and motility. The influence of the age was made along two years, studying the dynamics of the sperm parameters. Statistical analysis was performed as per standard statistical methods. The results reveal the fact that the best performances were recorded in bulls up than three years old. The study clearly demonstrates that there is a variation in reproductive parameters in the buffalo bulls, which could be studied at the molecular level to unveil any genomic markers associated with low fertility and/or infertility. The males may be used to obtain semen by subjecting the young ones to training at an early age, thereby decreasing the initial age of semen donation.
