Caffeine- is it effecting your fertility?

Now, I am a devot caffeine drinker- I am addicted to diet soda and I love coffee- but I have done some research on the effects of caffeine and our fertility and this what I have found:

One study showed that women who ingested 300 mg. of caffeine per day or more had a 27% lower chance of conceiving than those who had no caffeine. But other studies have suggested little or no correlation between caffeine and fertility. So there is really no concrete evidence that shows that caffeine equals infertility. However
to be on safe side, if you're trying to get pregnant, it's probably wise to cut back on the caffeine. Most experts agree that moderate amounts of caffeine — less than 300 mg. a day — don't appear to affect a woman's fertility. Becaue remember when you are pregnant you have to limit your caffeine, so why not start early.

A great alternative is to switch to caffeine free soda- or start drinking Perrier water- it still has the fizz like soda. Also those new fruit drink, Izze's are great, they are 70% fruit juice and again have some fizz to them, but no caffeine. So think ahead and be healthy, why take any risks!?
