this food can lower fertility
A natural chemical found in soy, tofu and legumes can potentially damage sperm and lower men's fertility, Reuters reports of new research from King's College London.
The plant chemical, genistein, mimics the effect of the female hormone estrogen and in turn affects sperm in laboratory mice. Tests in humans have shown an even stronger impact than in the rodents. Research leader Lynn Fraser found in lab tests that small amounts of genistein can cause human sperm to "burn out" and lose fertility, reports Reuters. :no: to soy protein
