Did you know that in 1938, only half a percent of men were infertile? By the 1990's, this had risen to 12% of men. Some of the reasons for this are thought to be car emissions, chemical solvants and leads in household cleaners and paints and the use of pesticides in the food chain. Prior to the mid-forties and early fifties, most foods were produced organically. (Dr. Cecil Jacobson, Reproductive Genetics Center, Vienna, Virginia).

Mass vaccination may also be a contributory factor. Although vaccines go through safety and efficacy trials prior to being released to the public, according to all the manufacturer's data sheets which come with each vial of vaccine, 'this product has never been evulated for it's reproductive, carcinogenic or mutagenic effect' (i.e. vaccines are not tested for their effect on fertility, or whether they will cause cancer or mutate into other illnesses). Since no reproductive studies have ever been undertaken, it is impossible to evulate whether or not the ever increasing vaccine programmes would have an effect on fertility.
