Background: As sex and gender are important considerations in the assessment of toxic chemicals, we investigated whether sex and gender issues have been adequately considered in toxicological databases. Materials and Methods: A systemic review was conducted on the toxicity and epidemiology data of eight environmental chemicals (i.e., cadmium [Cd], lead [Pb], benzene, toluene, formaldehyde, and tetrachloroethylene [TCE], bis(2-ethylhexyl) phthalate [DEHP], and bisphenol A [BPA]) that appear in three toxicological databases (i.e., Hazardous Substances Data Bank, Integrated Risk Information System, and the European Chemicals Agency databases). Results: Systemic reviews on 4160 data entries pertaining to eight chemicals in three databases revealed that only 13.5% of these were sourced from male and female combined (MF) studies, whereas, 40.6% of the total number of examined entries was sourced from the study in which the sex of the subject was not mentioned. Conclusions: To accurately evaluate the hazardous effect of chemicals, toxicity tests should be designed and conducted for both sexes, and the corresponding endpoints should cover gender concerns. Therefore, databases listing toxicity data as part of the open source literature should select information from MF toxicity and epidemiology studies.
