A man has had to undergo surgery on his vital organ after his penis got stuck in a metallic nut he was using during masturbation.

A Twitter user identified as @MikeHell7 told the story of the incident.

He shared photos of the man lying on an operating table as the doctors attended to him.

The poster wrote:

“A Nigerian guy once tried to masturbate using Nuts and Bolts. This is how it ended; Doctors had to operate on him to remove it. Was it worth the nut?”

From the photos, the penis went all the way through the nut and got stuck at the base of his manhood.

The pressure on the stangulated organ caused it to swell.

Here are some reactions to the incident from netizens on Twitter:
