I’m sure this happens all the time.
A 2cm long fish apparently found it’s way into the penis of a 14-year-old boy from India in a bizarre medical case.
The patient was admitted to hospital with complaints of pain, dribbling urine and acute urinary retention spanning a 24-hour period. According to the boy, the fish slipped into his penis while he was cleaning his aquarium at home.
This is precisely why, when I’m cleaning the bank of tanks in my lab, I make sure to keep my pants on.
