Abstract
Preconception health is defined as the physical and psychological well-being of women and men throughout their reproductive life. It is a method that raises healthy fertility and focuses on activities that persons can take to minimize risks, raise healthy lifestyles, and increase preparation for pregnancy. The purpose of this systematic review study was to assess men's knowledge of preconception health. Electronic databases, including Web of Science, PubMed, Scopus, Sciencedirect, ProQuest, Cochrane, SAGE, Springer, Google Scholar, were searched for published studies from 2000 to March 2021 to identify the studies carried out on men's knowledge of preconception health. The quality assessment was done using the critical appraisal skills program tool for qualitative studies and the Newcastle-Ottawa scale for cross-sectional studies. Of the 1195 references identified in the initial search, 11 studies met the inclusion criteria. Because of the diversity in the study design and the data collection tools used in studies, meta-analysis was impossible. All the studies of the present systematic review found that men's preconception health knowledge is poor. This systematic review showed that men's preconception health knowledge is low. Due to the limited studies of men's knowledge about the importance of optimizing their health before pregnancy, further study of the issue is still required.
