To be honest, this has thrown me as well - I've been a veggie now for about 15 years, and don't intend to eat meat in the near future! I actually asked my consultant about it last week, and he said my diet is a lot healthier than many meat eaters, and that in his opinion, it wasnt affecting my chances of concieving.
I tend to stick to Quorn more than Soya, or Tofu, so I'm not sure if this really applies to me.
However, the report also said we should steer clear of 'peas and beans' and I must admit to thinking 'whatever next'

I'm sorry, but how can vegetables be bad for you?
The Sun also ran the headline 'Veggie diet causes infertility' which immediatly made me worry, but it was about the soya again.
I'd say to take this with a pinch of salt - if you do eat a lot of soya, perhaps switch to a different source, but to be honest, I personally think you'd have to eat a whole lof of soya to make a harmful effect!
Hmmmm better see what I've got in for dinner .... best not eat any peas!
