: Continuous exposure to cigarette smoke has been reported as the number one cause of infertility in men. Cigarette smoke increases the production of reactive oxygen species (ROS) thereby causing infertility in men. Nigella sativa contains antioxidant that may decrease ROS level in hope to improve infertility. This 50 days study is conducted to see the effect of Nigella sativa extract to the sperm quality of nine wistar rats that have been exposed by cigarette smoke. The rats were divided into three groups of three: the control group and the group treated with Nigella sativa administered orally at the dose of 200 mg kg body weight and 400 mg/kg body weight. Sperm quality was observed by overlooking at the concentration, motility, and morphology of each group. The mean data of each group was obtained and tested for significance using Independent Samples T-Test. This study found the comparison of both motility (p=0,006) and morphology (p=0,000) between control group and the group with the dose of 200 mg/kg body weight to be significant, as well as the comparison of motility (p=0,001) and morphology (p=0,000) between the control group and the group with the dose of 400 mg/kg body weight
