Female physicians in the U.S. continue to earn less than their male counterparts, with the pay gap widening during the past two decades to more than $50,000 annually in 2010, researchers said. Women doctors had a median annual income of $165,278 from 2006 to 2010, compared with yearly earnings of $221,297 for male physicians, according to the report published today in JAMA Internal Medicine. While the annual pay for women doctors has increased since the median of $134,995 in 1990, it's only now beginning to approach the $168,795 annually earned by men 20 years ago, the researchers found.
