A 44 year old man woke up from a boozy night out to discover his genital has been chopped off.
Tan Nan had been eating and drinking with friends when he became so drunk he fell asleep.
Police are investigating the baffling case which happened in China.
Tan told officers he has no idea who was responsible for the cruel prank.
Several hospitals apparently turned him away as they were not equipped for such an operation.
Finally, he was taken to Changsha Hospital and treated by microsurgery experts.
According to the report after seven hours of surgery, the genitalia was successfully reattached.
However, it remains to be seen whether the urinary function and sexual function can be restored. The doctor believes that it is expected to gradually recover.
The police have been notified about the attack and are looking into it, but the victim is still not fully recovered enough to face questions.
