The coaches of five of South Korea’s seven female soccer league teams have threatened to boycott the national competition unless Seoul City Amazons striker Park Eun Seon succumbs to a gender test proving herself to be female.

This would be the second official gender test Park must undergo, as the Korean Football Association has already tested her once before in 2004 for the Athens Olympics. At 1.80 meters tall and 74 kg (163 lbs), the twenty six year old was named best forward this season, with 19 goals in 22 matches.

"My heart aches and it is humiliating," Park wrote on her Facebook page, "I've been through gender tests many times and competed in the World Cup and the Olympics." Amazons club manager Seo Jung Ho came to her defense, saying it was a "conspiracy" because others were suspicious of her comeback after a previous slump.

Park has vowed to stay strong, "I know these people are trying to destroy me ... In the past, I would have thrown my hands up and left, but I've worked so hard to get to this point, and I will not give up so easily."
