One of Zimbabwe's leading junior athletes, who has won several gold medals in women's events, is really a man, police say.
Samukeliso Sithole, 17, has been charged with impersonation.
At her court appearance, she insisted that she was a woman, despite a doctor's report to the contrary.
Ms Sithole said she was born with both male and female sexual organs and a traditional healer had made the penis disappear but it had since regrown.
She told the court that the penis had returned because the healer had not been fully paid for his services.
