Since the early 1980s community are suffering from chronic arsenic toxicity due to exposure through arsenic contaminated groundwater used as drinking water in eight districts of West Bengal and forty four districts of Bangladesh. The water concentration of underground arsenic contamination ranging from below 50 μg/L to above 500 μg/L in different parts of West Bengal, i.e., Murshidabad, Nadia, 24-Parganas (North & South) and Malda was observed (Das & Roy Chowdhur, 2006). Major clinical manifestations of As exposure are hyper pigmentation, keratosis, weakness, anemia, burning sensation of eyes, swelling of legs, liver fibrosis and chronic lung disease. The effect of As in relation to male reproductive function is not well established (WHO, 1981; Pershagen, 1983). Therefore, both epidemiological and experimental study were undertaken to ascertain the effect of As on male reproductive function, if any.
