Here's a look at some of the top health news being talked about around the U.S. and the world today:

• The Milwaukee Teachers Education Association has filed a lawsuit against the Milwaukee school district, claiming distrimination against men after the district decided to cut erectile dysfunction drugs from its health insurance plan to save money, ABC News reported.

• Doctors thought a 75-year-old man's lung troubles were likely cancer. But instead, it turned out a pea plant had sprouted inside one of his lungs after, they say, a seed had went down the wrong way.

• A new antibiotic-resistant mutation in some bacteria, being called a "super bug," has become more common in India and Pakistan, and in some cases appears to have spread to Britain and the United States, the New York Times reported.
