Source: Sperm Count Dropping in Western World – Scientific American
Sperm counts in men from America, Europe, Australia and New Zealand have dropped by more than 50 percent in less than 40 years
“An unanswered question is whether the impact of whatever is causing declining sperm counts will be seen in future generations of children via epigenetic (gene modifications) or other mechanisms operating in sperm,”
— Daniel Brison, a specialist in embryology and stem cell biology at Britain’s Manchester University
“Given that we still do not know what lifestyle, dietary or chemical exposures might have caused this decrease, research efforts to identify (them) need to be redoubled and to be non-presumptive as to cause.”
— Richard Sharpe at Edinburgh University
