A young, German tennis player’s making the world reconsider the meaning of "gender."

Sarah Gronert, 22, was born with both male and female genitalia. However, after undergoing surgery, she’s now medically — and legally — a woman. But, sadly, Gronert still endures constant scrutiny from peers and opponents’ coaches who claim Gronert should not be eligible to compete in the women’s tennis circuits.

"There is no girl who can hit serves like that, not even Venus Williams," said Schlomo Tzoref, the coach of player Julia Glushko, reports Fanhouse. Glushko lost to Gronert in a tournament in Israel in early March. "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. If she begins to play continuously, within six months she will be within the top 50."

Gronert, ranked No. 619 in the world, considered quitting tennis at the age of 19 due to the intense ridicule. Fanhouse says the young woman’s Wikipedia profile has been taken down due to "constant abuse by users."
