The rapper and actor T.I. prompted widespread outrage after revealing on a podcast that he has accompanied his daughter, now 18, to a yearly doctor’s appointment to ensure that her hymen is still intact.

Scientists have long condemned so-called virginity testing as a violation of a woman’s rights, as well as a sham procedure unsupported by evidence.

“A virginity exam does not exist,” said Dr. Maura Quinlan , an associate professor of obstetrics and gynecology at Northwestern University in Chicago. “If someone brought me a girl for a virginity exam, I would tell them, ‘I can’t say either way.’”

In a podcast interview that aired on Tuesday, T.I. — whose full name is Clifford Joseph Harris Jr. — said he made “yearly trips” to the gynecologist with his daughter, even though she is now 18 years old and in her first year of college.
