What goes up must come down — unless you’re a mountain biker whose pecker stays erect for so long that medical intervention is necessary.
After a month of gravity-defying behaviour, the offending organ was finally laid to rest at Tallaght Hospital in Dublin.
The Hell on Wheels erection occurred after the unnamed cyclist sustained an injury on the crossbar of his mountain bike that resulted in irregular bloodflow to his penis.
A report in the Irish Medical Journal into the treatment reported that his pain, and bruising settled within days, but that he sustained ongoing "high-flow" priapism "with rigid erection".
Priapism is defined as a prolonged, unwanted erection for more than four hours in the absence of sexual stimulation.
The man did not present at Tallaght Hospital until five weeks later, and medics say the initial examination "revealed no signs of injury, but penis was erect".
Medics initially tried to treat the condition with "manual compression" that resulted in the resolution of the erection, but it rapidly returned.
The staff then tried a pressure dressing that was in place for two weeks "but release of pressure caused immediate recurrence of priapism".
Medics eventually treated the man after inserting gel foam and four tiny platinum coils at an abnormal connection between an artery and a vein that supplied blood to the man’s penis. This reduced the high-flow blood supply to the penis, ending the erection.
One of the medics, consultant intervention radiologist at Tallaght Hospital Ronan Browne, said yesterday: "We were very happy with the outcome.
"It was an anxious time for the patient, as it would be for any young man."
The man received a sedative but was conscious for the procedure.
Dr Browne said the treatment carried a small risk of impotence but the patient reported no recurrence of priapism and satisfactory erection and sexual intercourse. Dr Browne said that the case was "unusual".
