Don't try this at home. Or any where else for that matter.
A man was left with a swollen and painful penis thanks to injecting himself with petroleum jelly in the hope it would make his manhood bigger.
Father-of-one Szilveszter, 24, who now lives in Bolton, feared he would never be able to have more children after the DIY procedure left him unable to be intimate with his wife.
He said: 'I had to stop trying with my wife as it's too painful. I would like to have more children but if I can't, I may lose my family.
'Every day is difficult for me as it's very painful and bleeding. This was the worst mistake in my life as I don't feel like a real man.'
Hungarian born Szilveszter shares his story on the latest series of TLC show Extreme Beauty Disasters. He said he had Vaseline injected into his penis following a friend's recommendation
Szilveszter turned to Extreme Beauty Disasters resident plastic surgeon Dr Vik Vijh who said there was hope he could be cured - but it wouldn't be easy.
After examining Szilveszter Dr Vijh said: 'It's not a pretty slight, it's inflammed, it's sore, it's misshapen, his penis is a disaster.'
He added: 'I have been doing plastic surgery now for 20 years and I have never seen anything like this. Injecting petroleum jelly into the penis makes no sense on any level.'
The cosmetic surgeon said the only option would be for Szilveszter to have an operation where his penis would be 'skinned' to remove the Vaseline and scar tissue.
'I have never done this before but fingers crossed we can save his penis,' Dr Vijh said.
After hours of surgery, the operation was a success.
As a result of Dr Vihj removing all the Vaseline and scar tissue, Szilveszter is now back in full health following his recovery from the operation.
He said: 'I am much better. It has healed well, it's painfree and working. I can have sex with my wife again.
'Many people said we can't help you. Dr Vijh did a perfect job, he has changed my life.'
The father said he had learnt his lesson and won't meddle with his penis size again.
