fatherhood

Texas Rangers shortstop Elvis Andrus became a father last summer, so the off season has been full of spit up, late-night feedings, and smelly diaper changes. Glamorous! But Rangers fans can be excited knowing that Elvis expects fatherhood to make him an even better player this season.

In the first study of its kind, researchers compared the testosterone level of men when they were single and childless to their testosterone level after they had had a child. While testosterone always decreases when men age, the decline was much more pronounced among the men who had become fathers.
