Germany’s Sarah Gronert is a professional tennis player who competes on the same level as the Williams sisters and Maria Sharipova. The thing is, Gronert was born with both male and female sex organs (i.e. she’s a hermaphrodite), though she had surgery a few years ago to remove the male genitalia. Her story ignited controversy in her own country and within the professional tennis world, but she was able to plead her case with the WTA (the group that oversees the sport) so that she could continue to play among her female peers. But her critics believe that the fact that she was born both as a man and a woman gives her an unfair advantage competing against women. “There is no girl who can hit serves like that, not even Venus Williams,” said Schlomo Tzoref, who coaches rival player. “When I heard her story, I was in shock. I don’t know if it’s fair that she can compete or not. She does have an advantage, but if this is what the WTA have decided, they probably know best.” Apparently, Gronert is so good, she’s expected to be crack the Top 50 players in the world this year.
