The beijing olympics has been a success, no scandals have been reported. I did a google search on Olympic scandals and I only got scandals from the past. The most interesting bits were about the following women athletes who were suspected to be men.
Polish Runner Ewar Kobukkowska
She was the first woman to be caught in a gender test in 1967. In 1964 summer olympics in Tokyo, She won gold medal in women 4 x 100 meter relay and the bronze in womens 100 meters sprint.
She was found to have a rare genetic condition which gave her no advantage over other athletes, but was nonetheless banned from competing in the Olympics and professional sports.
Indian Runner Santhi Soundarajan.
She won the silver medal in the 800 meters track event at the 2006 Asian games in Doha, Qatar. She failed a the sex determination test and was stripped of her medal. Her case is yet to be concluded however.
Soundarajan is reported to have lived her entire life as woman.
Brazilian Judo, Edinanci Silva,
At Sydney, she beat Australian Judoka Natalie Jenkins. At a press conference Jenkins raised the issue of Silva’s gender by constantly referring to her as “he” Eventually Silva was confirmed as female but not without some considerable embarrassment.
German athlete, Dora Ratjen
In 1936 a German athlete named Dora Ratjen finished fourth in the women’s high jump. Twenty years later, Ratjen disclosed the he was in fact Hermann Ratjen and that the Nazis had forced him to compete as a woman.
Brazil Women Vollyeball team
After 2000 Sydney Olympics I remember reading about How volleyball teams had complained about the Brazilian volley team. The team officials admitted some of their players were formerly hermaphrodite but they had undertook an operation to be women. Even after the IOC confirmed the players to be men, most girls from the other teams continue insist they had played against men.
