The research on whether caffeine can affect fertility is mixed. Experts generally agree that low to moderate caffeine consumption (less than 300 milligrams a day, or about two 8-ounce mugs of coffee) won’t get in the way of getting pregnant.

But you might want to cut out caffeine altogether if you’re having difficulty conceiving or undergoing in vitro fertilization. Until science shows with certainty that caffeine intake doesn’t affect fertility, why take a chance?

Caffeine can also hinder your body’s ability to absorb iron and calcium, and advises giving it a pass.

Going cold turkey and eliminating all caffeine at once can cause nasty headaches. So if you decide to kick your caffeine habit completely, you might want to do so gradually.

Every day, replace a little more of the caffeinated brew in your cup with decaf, until you’ve weaned yourself. Once you’ve adjusted to life with little or no caffeine, you may find steamed milk with a shot of flavored syrup a nice coffee substitute – and the calcium will do your body good.
