BPA is used to make plastics and epoxy resins and is found in the lining of food and beverage cans, baby bottles, CD cases, plastic knives and plastic forks. It is one of the world’s most widely manufactured chemicals. This was one of the first human studies of its kind and was published in the journal “Reproductive Toxicology”. Researchers detected BPA in about 170 of the 190 men tested. They measured concentration, motility, shape and DNA damage in sperm. The results of the study showed that men with the highest levels of BPA had sperm concentrations 23 percent lower than men with the lowest levels of BPA. Results also showed that ten percent in sperm DNA damage.
