Man admits guilt over DIY testicle surgery

A DIY "doctor" accused of slicing off a man's testicle in a NSW mid-north coast motel room has admitted a charge of illicitly removing another person's bodily tissue.

Police say Allan George Matthews, 56, responded to an online advertisement posted in May by a 52-year-old man requesting help with a medical issue.

The two men then met at a Port Macquarie motel where the younger man's left testicle was allegedly surgically removed by Matthews, who police say is not a qualified doctor.

A week later, the younger man showed up at hospital seeking help with a wound he had sustained during the illicit operation.

Matthews faced Port Macquarie Local Court on Wednesday and entered a guilty plea to a charge of removing tissue from the body of another person without proper consent or authority.

He has also admitted charges of possessing a prescribed restricted substance, unauthorised possession of a firearm and failure to keep a firearm safely, but will fight a charge of reckless grievous bodily harm, according to court records.

He is yet to enter a plea to the charge of causing grievous bodily harm with intent.

Matthews will remain on bail until his case returns to court on August 18.
