Surgeon Dr Tristan de Chalain said men were just as sensitive about their appearance as women.
"It's exactly the same motivation - you have embarrassment about a particular feature ... and they want to compete with younger guys," he said.
"And often it's not unusual for wives to send their men to have something done."
Gynaecomastia - the male boob job - was particularly popular.
"Basically, men - particularly as they get older but even when young - develop a female-like breast. It's very easily treated."
People went through long consultations - it was not a snap decision - and most came out feeling they had received a new lease on life, Dr de Chalain said.
Psychologist Karen Nimmo said it was a surprising result given the greater insecurities among women about their appearance.
The poll also showed a sharp divide by age: 19 per cent of those from 40-54 would consider surgery, but nobody aged 55-69 said they would.
