Data collection of independent variables with questionnaires and dependent variables by means of medical records. Data analysis using logistic regression test. Based on the results of logistic regression statistics, the wife's physical activity variables were p value 0.484 and husband's p value 0.628, wife's nutritional status p value 0.651 and husband's p value 0.392, wife's smoking p value 0.999 and husband's p value 0.028, wife's diet p value 0.306 and husband p value 0.138 then infertile incidence simultaneously influenced by the variable significantly p value 0,000 at α = 0.05. Infertility events are jointly influenced by physical activity, nutritional status, smoking and diet, and can be influenced by other factors related to reproductive organs in couples of childbearing age.
