Analysis of semen was done for semen volume, sperm number, sperm motility and presence of other cells.Results: 7.45% samples were of inadequate quantity. 19.87 % of cases had oligozoospermia, 12.42% had azoospermia and 4.35% of males had asthenozoospermia. Pus cells were found in 12.42% cases.Conclusions: Majority of the cases of infertility in males is due to oligozoospermia followed by azoospermia while less sperm motility or less amount of semen are also responsible in some cases
