The study was a case study research design which involved the sample size of 95 married households of men and women aged between 18 to 45 years of age residing in Butimba ward. Multistage sampling technique was employed in selection of household, rotary method was used to select streets whereby 5 streets were selected out of 9 streets in Butimba ward and households were selected using systematic random sampling. Questionnaire and interview data collection techniques were employed whereby findings shows among of the barriers which hinder married men to participate in family planning was lack of time and the nature of services provided hinder men to participate since majority of the respondents mentioned programs targeted to women only.
