Having trouble conceiving? Your blood type may be to blame, according to a new study from researchers at Albert Einstein College of Medicine in New York and reported by the UK’s Telegraph.

The study results, which were presented yesterday at the annual conference of the American Society for Reproductive Medicine, found that women with type O blood -- the most common blood type in the U.S. -- who were seeking fertility help were more likely to have trouble getting pregnant than women with other blood types.

The study involved 560 women (average age: about 35) who were being treated for infertility and measured their follicle-stimulating hormone (FSH) levels. The type O gals were twice as likely to have FSH levels that were above normal, meaning they’ve got fewer good eggs.

However, the study didn’t measure other fertility indicators or look at women who weren’t already being treated for fertility issues. And some researchers quoted in articles about the study cautioned women with type-O blood not to stress. Still, it’s one indication that if you’re type O, it may be better to try for a baby sooner rather than later.
