The youth called the emergency line for help when the attempt to free himself went wrong, resulting in profuse bleeding in the 4am incident.
The emergency rescue team from the Andalas Fire and Rescue Department arrived at 5.25am following a distress call at 4am.
They took about 10 minutes to cut open the plastic bottle and stop the bleeding before taking the man to the Tengku Ampuan Rahimah Hospital.
A Fire and Rescue Department spokesman said the man claimed his penis got stuck in the bottle when he tried to urinate into it at home in Gong Badak, Port Klang.
