Soya contraceptive
It's not a good week for making babies. First there was the announcement of a coming "infertility timebomb" fuelled by the trend of later motherhood, obesity and STDs. Now it turns out that the vegan's friend, soya, could impair the performance of sperm. Even a small amount in a woman's bloodstream can trigger sperm to produce a signalling molecule called cyclic AMP which is supposed to kick in as the tadpoles near the egg. naturally this leads to them burning out too early.The culprit in soya is a compound called genistein, a weak oestrogen. Similar compounds can be found in hop based products- ie beer- which is even worse news.
