Although Mr. Schwartzenegger has made the moniker "girly men" a widely recognizable sound byte, you guys should know it is a very real medical condition... and it even goes both ways. And no I am not talking about people who have taken hormones or resorted to surgery to change their outward sexual features.

Some people are girls on the outside with testicles on the inside. Some are male on the outside (albeit girly-looking men) with ovaries on the inside. Doesn't surprise me at all that the same thing happens to fish. There are a number of species where all the individuals start out life as males and only the largest in the school/colony transform into females.
