Two Hearts Of the Same Sex

It's like same sex marriage, but different. I'm talking, of course, about the latest medical study, which found that heart transplant patients have better odds of survival and a lower risk of rejection if they get organs from donors of the same sex. Size may be part of the explanation. Men's hearts are bigger than women's and have greater pumping capacity, and men who get men's hearts fare better.

The study was paid for by the federal government and led by Dr. Eric Weiss, a cardiac surgery researcher at Johns Hopkins University in Baltimore. He presented his findings Wednesday at an American Heart Association conference.

So sex matters. And size matters. Go figure.
