It is widely known that the use of toxic chemicals such as bisphenol-A (BPA) in food containers has been linked to a number of health problems including cancer, heart disease and infertility – see The Independent article.

Frank Sommer, a Berlin-based urologist, told The Telegraph newspaper that chemicals like BPA “could shift the balance of sex hormones in men towards oestrogen….[which] leads to less sexual drive.”
