A gel to increase sperm motility?

Perhaps this product has been around for a while and lots of couples are using it to try and conceive the natural way. But it's the first I have heard of it. It is called Conceive Plus gel and the claim is that it helps improve sperm motility.

At first that might seem like quite a claim but all they are really saying is that it is designed to mimic natural body fluids and give the best potential to the sperm. I'm not sure if that really qualifies for improvement of motility but it certainly is an improvement over other harsher artificial lubricants.
