An unidentified British man who was undergoing a minor operation was given a vasectomy by mistake.
The Telegraph have reported that the incident occurred at Royal Liverpool University Hospital, which is affiliated with the National Health Service, Britain's public healthcare system.
Doctors are currently trying to reverse the mistake, but the victim faces an anxious wait to see if he will be able to have children.
The man went in to surgery for a minor urological procedure, but doctors carried out an operation on the “wrong site”. They could now face a six figure compensation claim.
"We can confirm a patient who was scheduled to have a different minor urological procedure was wrongly given a vasectomy," RLUH medical director Dr. Peter Williams said in a statement.
"We have apologized unreservedly to the patient and we are offering him our full support. We greatly regret the distress this has caused him," Williams said.
Though vasectomies are mostly considered to be a permanent form of birth control, it is possible to reconnect the tubes that were removed in the procedure.
The man has not been identified and the NHS trust has refused to disclose his age because of patient confidentiality.
The success rate of reversing a vasectomy is between 40 and 50 percent, according to the Houston Fertility Institute
