The use of modern male contraceptives is much lower than among women in Indonesia, and there are quite large differences when compared to several countries in Asia because the use of modern male contraceptives from 2002-2012 in Indonesia was always low due to a lack of knowledge and negative perception about Family Planning. This study aimed to determine the role of knowledge and perceptions of family planning for use of modern male contraceptives in Indonesia. This research method used a cross-sectional design on a secondary basis based on the 2017 IDHS. The result of this study is that there is a relationship between knowledge and perception of family planning in the use of modern male contraceptives after being controlled by education level, area of residence, and fertility preferences. This study concludes that married men who use modern contraceptives are those who have good knowledge and positive perceptions about family planning, found in married men who have a high level of education, live in urban areas, and do not want to have children anymore. This study recommends a particular male family planning program based on gender equality by prioritizing special substances regarding family planning knowledge and perceptions. © 2023, Universitas Negeri Semarang.
