Experimental studies suggest that large numbers of chemicals, environmental and industrial pollutants affect the male reproductive system. At present, almost no information is available on the effects of these adverse agents on human reproduction. Recent reports, however, suggest that in the past 50 years male fertility has declined based on qualitative and quantitative measurements of normal sperm. This study identifies‐among the active ingredients and solvents included in pesticide formulations registered in Italy‐the chemical agents with experimental evidence of male reproductive toxicity. Documents produced by international agencies and organizations such as IARC, EPA, WHO, and original papers from the international literature were systematically reviewed. The results indicate that several pesticide products notified in the Italian Registry contain active ingredients and/or solvents severely affecting testicular function and sperm morphology in laboratory animals. Therefore, exposure to reproductive toxicants occurring among manufacturers and users of pesticide formulations registered in Italy suggest further epidemiologic surveys should be conducted in this area.
