For this week's CommonHealth segment, we look at a fertility study that has hundreds of men revealing the intimate details of their lives, from their coffee habits to their underwear preferences. Led by researchers at Boston University, Pregnancy Study Online or PRESTO, includes nearly 3,500 women and 945 men from the U.S. and Canada.
