A British man has become the first reported case of a man breaking his penis vertically.
The unnamed 40-year-old injured himself while having sex, with doctors stating that his appendage simply 'buckled'.
The British Medical Journal (BMJ) states that a broken penis, or penile fracture, occurs when the protective layer around the erectile tissue, which pumps blood to the penis, is damaged due to an 'unusual bending'.
The 'break' causes the penis to become 'grossly swollen' and bruised.
According to the journal, the case study's willy 'buckled against his partner's perineum (the area between the anus and the genitals)'.
However, unlike most penile fractures, the man did not report having heard the usual 'popping' sound.
His erection also faded over time, while in cases such as this the erection is usually lost almost instantly.
And stranger still, an MRI scan found that the man's member had a three-centimetre-long vertical tear on its right-hand side.
In cases such as this, experts say it's vital a patient is seen by a medical professional within 24 hours of it happening.
If this doesn't happen, there is the risk that it could cause long-term and potentially irreparable damage and erectile dysfunction.
Luckily for the man in question, he underwent surgery which was successful and was able to have sex once again a few months later.
The journal entry concluded by asking: "Does a vertical penile fracture pattern alter either the presentation or long-term outcomes following operative repair?
"Of course, more work is required to answer this question, however based on this case, it would appear that a vertical fracture is not associated with the classical features of a penile fracture, namely immediate detumescence, a 'popping' sensation, gross ecchymosis and a palpable rolling defect.
"This patient was able to resume sexual activity within six months of the injury, achieving erections of the same quality to those prior to the injury, denying any penile curvature or significant palpable scarring."
But while he may be the first to have suffered a vertical break, the man above is not the first to have injured himself while making love.
Back in 2018, Steven Horden, 37, from Kent, and his girlfriend Kiera Diss, 38, were having sex, trying for a baby, when the unthinkable happened: his penis 'snapped in half'.
Steven was rushed to hospital and his bloodied and bent organ was treated, but the horror was yet to come when he saw how badly damaged his Johnson was.
During the four days he spent in the facility, he had to have a circumcision after doctors found it difficult to insert a catheter.
