This study assesses the determinants of family planning methods use by Turkish married men in South East Anatolia. A descriptive and cross-sectional survey research design was used among 1,352 men aged 20 to 52 years who lived in South East Turkey. A pilot-tested questionnaire was used to collect data. Descriptive statistics, chi-square, and multivariate regression analysis were used. The rate of nonusage of contraceptive methods among the participants was 60.4%. Within the nonusers, 34.9% reported a religious prohibition and 9.4% had misconceptions about family planning. Chi-square analysis determined four factors that were significantly related to the men's usage of contraception. These factors are the following: the men's age, educational level, number of existing children, and their perception of their household income level. These four factors were also subjected to multivariate regression analysis, the results of which were used to compute odds ratios for each value of each factor indicating the likelihood for using contraception by men within each group. Male-specific family planning programs can make an important contribution to the overall efforts to improve the usage of contraceptives by men. It is important to note that family planning services and education programs related to family planning should be appropriate for men.
