The 68-year-old gynecologist Giovanni Miniello from Bari is formally investigated with the hypothesis of a crime of sexual violence.
In the service, the doctor proposed sexual intercourse to some patients as a cure for the papilloma virus.
Miniello, after the outcry caused by the news, asked for the cancellation from the register of doctors.
The Order had already opened disciplinary proceedings on the case.
The criminal investigation is coordinated by the 'weak bands' pool of the Bari Public Prosecutor's Office.
