A man fractured his penis after it buckled against his partner while having sex in a notoriously risky position.

The 37-year-old, from Indonesia, showed up to hospital with a swollen, bloody and severely bruised penis, which doctors said resembled an aubergine

The patient explained that he heard a 'loud popping sound' while having sex a few hours earlier in the reverse cowgirl position — when the woman is on top and faces away from her partner.

The man explained that he was having sex in the reverse cowgirl position when he suddenly heard a crack.

The man immediately felt severe pain, lost his erection and began bleeding out of his penis. The patient was also unable to pass urine.

Doctors said the patient had suffered a significant hematoma — an injury to the wall of the blood vessel, which causes blood to seep out into the surrounding tissue.

They noted that his penis was left with the 'eggplant deformity' — when it swells and turns purple — which is a tell-tale sign of a fractured penis.

The man was rushed into surgery, where doctors made an incision into the tip of his penis to 'deglove' it — when the top layers of skin and tissue are removed.
