Neven Ciganovic was left with a priapism – an unwanted, long-lasting and painful erection that is not accompanied by sexual desire

The 45-year-old Croatian said: ‘I was in Iran for rhinoplasty for the documentary film that British Channel 4 is filming covering my life.

‘We did not record the surgery but only the consultation sessions with the doctor. They gave me general anaesthesia and I reacted badly to it.’

According to Neven, it was during the surgery that he was diagnosed with priapism.

He recovered in a hospital in Serbian capital Belgrade, but says he was refused painkillers despite being in agony.
