A doctor groped his female patients' breasts for pleasure during medical exams over the course of 20 years, a court heard.
Channarayapatna Krishna, 58, is accused of assaulting seven women between 1996 and 2017 while working at the Royal Gwent Hospital in Newport and University Hospital Llandough near Cardiff.
The consultant allegedly rubbed one woman's breasts 'in a circular motion' after asking her to remove her top and bra and groped another by touching her nipples.
He is also accused of kissing a colleague on the lips against her will and trying to force her against a wall.
Krishna, of Penarth, denies 11 counts of sexual assault and one count of indecent assault.

Prosecutor Matthew Cobbe said Krishna abused his patients' trust to gain 'sexual gratification from unnecessarily exposing and touching' their breasts.
He said many of the appointments began with a 'legitimate' examination but were soon conducted in a 'wholly unnecessary and intimate' way.
Mr Cobbe said: 'The patients were left uncomfortable, upset and bewildered by his examination and several recognised that the examination had been obviously unnecessary.
'But it is the prosecution's case that he was a doctor, and he got away with it until 2017.'
During one alleged incident at the Royal Gwent Hospital dating back to 1996 it was heard how a patient claims she was told to remove her blouse and unhook her bra during a routine appointment before the defendant touched and rubbed her breasts in a 'circular motion'.
On another occasion at University Hospital Llandough Mr Cobbe described how a patient was allegedly told to remove their clothes 'from the waist up' before being examined with a stethoscope.

Despite feeling uncomfortable it was heard how she had 'persuaded herself that Dr Krishna was a doctor and therefore professional'.
In subsequent appointments the patient was reportedly subjected to further breast examinations despite them being 'neither necessary or justified' and having received an all-clear from a breast clinic.
The court heard an investigation began when one woman complained to her GP and the hospital and it was later referred to South Wales Police.
Mr Cobbe said that during police interviews Krishna denied one patient had taken off her top and denied touching her breasts.
He also said he could not remember seeing a number of other patients but accepted he had made medical notes relating to their appointments.
In another case he denied rubbing his patients' breasts and when asked about forcefully kissing his colleague said it was not his intention to kiss her on the lips.
Krishna, of Penarth, denied touching or rubbing the women's breasts and said he could not remember seeing some of the patients.
The trial continues.
