The performance of infertile couples was maintained, their quality of life improved, and medical costs were decreased as a result of improving their lifestyle.To accomplish the initially stated goals, the present study used a cross-sectional descriptive approach. From December 1st, 2021, through May 14th, 2022, the study was in progress. In an infertility clinic in Al-Najaf City, Iraq, the study is being done. 200 women and men who visited infertility clinics at Al-Najaf Al-Ashraf Health Directorate were included in this non-probability (Purposive sample) sample. The process of gathering data involves developing a questionnaire utilizing an interviewing technique with both men and women, using the Arabic questionnaire version, and it is divided into three sections: Socio-demographic data and reproductive characteristics and standard Health_ Promoting Lifestyle questionnaires. The findings indicated that participants don't always engage in healthy behaviors to the required extent. These behaviors significantly contribute to improving life quality, preserving health, and fostering fertility. It is imperative to offer techniques, especially those that are consistent with predictors of health promoting activities, in order to enhance the health condition of infertile couples.
