Reports have suggested that male fertility has declined worldwide, possibly as a result of exposure to chemicals. Though it’s unclear which chemicals are directly responsible for decreased sperm counts, a few compounds have been identified:
Cookware. Non-stick coatings such as Teflon contain perfluorinated compounds (PFCs). These compounds have been found to correlate with decreased sperm count and increased abnormal sperm.
Fish. Fish from contaminated water may contain Polychlorinated Biphenyls (PCBs). PCBs have been linked to decreased sperm quality, sperm DNA damage, and lowered testosterone levels, all of which decrease fertility.
Fat. PCBs are also found in animal fats. Therefore, try to limit the amount of animal fat you consume by choosing low-fat meats and cooking methods.
Cans. Bisphenol-A (BPA) is often found in the lining of food storage cans. BPA is a hormone disruptor that has been found to decrease sperm concentration and sperm mobility. Increase the amount of fresh foods in your diet to decrease circulating BPA.
