No, it's not that scientists can't decide on a name. Folate is what we call the natural vitamin that's found in foods, while folic acid is the man-made version that you find in supplements.
It's also added to your pasta, cereal, flour and all of your other enriched grain products, if you live in the United States. The U.S. Food and Drug Administration (FDA) mandated its addition in 1996 once researchers discovered that it reduces the risk of serious birth defects, such as spina bifida, in babies. (If you're trying to conceive, make sure she's getting the folic acid she needs.)
But besides this incredibly important advance in medical knowledge, some studies have shown a connection between folate/folic acid and a reduction in abnormal sperm. Others even suggest it can help increase sperm count if you combine it with zinc.
Bag up some peas (black-eyed or otherwise), asparagus and avocado -- or, if you're more of the sweet-tooth-type, try bananas, papaya and cantaloupe. Tomato juice works, too, but we're not counting Bloody Marys.
