| Summary: | Background: The trend of male infertility is increasing and it correlates with industrial development which has introduced various industrial contaminants in the environment and human life. PFASs are one of those contaminants. Humans are exposed to PFAS through various routes and sources, especially through food and diet. On the other hand, some foods are beneficial for the male reproductive system. Aim: The study aim is to investigate the role of per-or poly-fluoroalkyl substances (PFASs) contaminated food in male infertility. Method: This study has used scoping review to assess the current knowledge concerning the aim that what has been done in this field. A systematic search was done in three databases namely PubMed, Web of Science, and Scopus, as well as manual search of related articles and reference lists during March-April 2023, and found 68 articles. Inclusion criteria included all articles written in English, related to humans, and PFAS exposure to adult males through food worldwide. Articles related to only the female population, other non-human species, human exposure to PFAS in fetal life, molecular level information, information about transport mechanisms of PFAS in food, other environmental contaminants and with no food contamination, toxicological, or health impact information were excluded. Titles, abstracts, and selected full-length articles were read and evaluated. CEBMa checklist for critical appraisal of the cross-sectional study, CASP checklist for systematic review, and randomized control trial were used as quality assessments of articles. Results: In total 68 abstracts were initially found, of which 15 were included in the review. Majority of the studies were either from Europe (European panel data from 16 different European countries) (n=2) or any European country (Italy=2, Georgia=1, Denmark=1, Sweden=1, Spain=1, Denmark + Sweden=1, Denmark + USA + Faroe Islands=1) and the rest were from USA (n=2), Australia (n=2) and Peru (n=1). The articles were analyzed according to the concept ...
