Egypt's military rulers have been ordered to stop the use of virginity tests on female detainees.
The ruling was made by a court in Cairo.
Activists, some of whom demonstrated outside the courthouse, hailed it as a victory over the generals who took control after President Hosni Mubarak was ousted earlier this year.
"Nobody would accept being subjected to such treatment," one demonstrator said.
"This is an indecent assault and a kind of torture, used as a way to pressure the revolution and to pressure women, so we don't speak out."
