We examined the degree of men’s modern contraceptive knowledge in Bangladesh and the associated determinants using the 1999-2000 DHS. The degree of knowledge was measured by the reported number of modern methods known among men aged 15-59 years. Although contraceptive knowledge was universal in Bangladesh, the degree of knowledge differed among certain subgroups. About 19% of men reported having had heard of 4-5 modern methods (mean: 6.9). Results from multinomial regression analyses showed that older,educated and those who were currently using modern methods were more likely to have had reported a high degree of knowledge (p<0.001). We conclude that men who had a low degree of knowledge seem not properly informed about the wide range of contraceptive options. It is imperative that family planning intervention strategies in Bangladesh should focus on the degree of contraceptive knowledge to improve the uptake of more male-based modern methods
