Those who are trying to use their diet to show how much they care about the fuzzy wittle animals and how ‘healthy’ they are, run the risk of not being able to reproduce.
A plant chemical found in soya, 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.
In laboratory tests, Fraser found that small amounts of the chemical can cause human sperm to “burn out� and lose fertility.
“Human sperm proved to be even more responsive than mouse sperm to genistein,� Fraser told a fertility meeting.
She added that if women eat soya 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.
While funny, it doesn’t really matter. The vast majority of tree huggers don’t have any balls in the first place.
