WASHINGTON - Estrogen fuels feelings of power and competition in women in much the same way testosterone does in men, researchers said on Wednesday in a study that shows the need to win is every bit as feminine as it is masculine.

Estrogen levels shot up in power-motivated women when they won and plummeted when they lost, while the opposite was true in women who appeared not to be interested in power, the researchers found.
