- Plant chemical may harm male fertility - Men's Health - MSNBC.com
A plant chemical found in soy, tofu and legumes could potentially damage sperm and affect male fertility, a British researcher said on Wednesday.
Professor Lynn Fraser, of King's College London has shown that genistein, which can mimic the effect of the female hormone estrogen, affects sperm in mice.
But it seems to have an even stronger impact on human sperm."
She added that if women eat soy and other foods high in genistein it might have a bigger impact on male fertility because the chemical is likely to affect sperm when it is in the female preparing to fertilize an egg.
"Maternal exposure to the compounds is probably more important than paternal exposure," Fraser explained.
Although it is very preliminary research, Fraser speculated that the findings could have an impact on women trying to conceive.
