A man shared the harrowing story of how he threw his penis in the bin after it fell off during Channel 4's documentary The Man With a Penis on His Arm, which aired on Tuesday night.
Malcolm MacDonald, 47, from Thetford in Norfolk, developed a long-term perineum infection in 2014 - between the scrotum and anus. He had become homeless and "did more drugs" when his relationship fell apart after welcoming a child.
The infection caused abscesses the size of "tennis balls", which "swelled and popped". He then developed sepsis - a life-threatening condition caused by an extreme reaction to infection.
