According to the study, the biggest offender was doggy style, which causes 41 per cent of penile fractures!
A group of researchers have established the three most dangerous sexual positions for men.
The experts looked at the relationship between sexual position and severity of penile fracture in heterosexual partnerships.
According to the study, the biggest offender was doggy style, which causes 41 per cent of penile fractures.
Missionary was the second most threatening, causing 25 per cent of penile fracture cases, followed by sex with the woman on top.
The research comes after a recent study which looked at the UK's favourite sex positions.
It revealed that while most dangerous, doggy style is also the most popular among sexually active Brits, with one in four citing it as their all-time favourite position.
The study's authors explained, "We do not observe differences between the severity of the penile fracture between the doggy style and man-on-top, but the doggy style had more severity of penile fracture when compared with woman-on-top."
They gathered data by examining 90 patients who had been diagnosed with penile fractures.
They subsequently assessed the dangers of different sex positions by analysing the mechanisms of each individual's injury.
Participants had an average age of 39. They also found that missionary and doggy style showed more associations with 'bilateral fractures of the corpus cavernosum and urethral lesions'.
