There have been some research studies focused on exogenous estrogen mimicking chemicals (Xenoestrogen). Some plastics exhibit these affects. "BPA (Bisphenol A) is the monomer used to manufacture polycarbonate plastic and epoxy resins used as a lining in most food and beverage cans. BPA global capacity is in excess of 6.4 billion pounds (2.9×109 kg) per year and thus is one of the highest-volume chemicals produced worldwide." -https://en.m.wikipedia.org/wiki/Xenoestrogen https://en.m.wikipedia.org/wiki/Xenoestrogen https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1469672/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1469672/
