which were divided into Group A (≥1 and ≤10 cigarettes/ day), Group B (>10 and <20 cigarettes/ day) and Group C (≥ 20 cigarettes/ day) and were analyzed for Sperm motility and vitality by ANOVATest.

Results : We observed that Sperm motility (p<0.01) and Sperm vitality (p<0.01) was significantly lower in Infertile Smokers group than Infertile Nonsmokers group. We also observed that Sperm motility (p<0.05) and Sperm vitality (p<0.01) was significantly decreased in accordance with the severity of smoking.
