Many aspects of our lives can potentially affect fertility, but there are few we can control.

Our environment, stress and sleep are difficult to change, and our genetics are what they are.

But diet is one of the factors we can, in theory at least, have some level of control over.

So, how can adjustments to our diet help aid fertility?

It is certainly a question the supplements industry has asked, the shelves of chemists sag under the weight of fertility supplements for men and women.

And, of course, there is an awful lot of myth, hearsay and tradition about foods which it is claimed can help you get pregnant.

But there is strong evidence too - and that is what we are interested in looking at. 

What does the evidence say about the link between what we eat and fertility for both men and women?
