Background: The level of fertility knowledge of reproductive-age people is low to moderate, and the inadequate knowledge of infertility-related factors may cause some people to unconsciously engage in activities that reduce their fertility. Given the significance of fertility knowledge, and the lack of standard instruments to evaluate it in Iran, the present study aimed at determining psychometric properties of the Persian version of the Cardiff Fertility Knowledge Scale (CFKS–P) in Iranian population. Materials and methods: In this cross-sectional study, a total of 280 participants (comprising 140 couples) attending mandatory pre-marriage educational sessions at two public health centers in Tehran were consecutively sampled from July to September 2021. The study examined the face, content, and structural validity (through confirmatory factor analysis) of the questionnaire. The reliability of the questionnaire was assessed using measures of internal consistency. Results: The structural validity of CFKS-P was approved with 13 items and two factors (basic knowledge of fertility and misconception about fertility) based on confirmatory factor analysis (RMSEA = 0.023, 90 % CI = 0.053–0.082, TLI = 0.916 and CFI = 0.972, χ 2 = 148.345). Kuder–Richardson coefficient of the scale was calculated to be 0.85. The overall percentage of correct answers for fertility knowledge was 50.76 %. Conclusion: The CFKS-P is a valid and reliable instrument for measuring the fertility knowledge in Iranian men and women. This scale can help the health care providers to assess the fertility knowledge of their clients or the quality of health education provided.
