Sex kills

Caution: If you're of mental age of 18 and below, kindly refrain from reading further. Consider yourself being warned.

Thus far, personally, the only sex-related injuries that I had attended before is post-coital vaginal injury.
3 patients.

1. Referred from casualty for heavy menses for 4 days. Intrigued by the history of having previous regular menses and just had her menses 1 week ago. Additional history confirmed the bleeding started postcoital. My fingers were able to felt the posterior uterus on vaginal examination. Unable to believe my tactile finding, confirmed it with a nearby pelvic ultrasound. Repair done in Operation Theatre. Unremarkable recovery.

2. Straight from Casualty to OT, white as sheet of paper. Young patient. Massive vaginal tear up to part of cervix near 3'o clock (the point for massive maroon tide). Sutured well up by my skillful specialist. Suspected the involvement of inanimate object in the sexual practice, did not confirmed it, though. Massive transfusion. ICU observation. Unremarkable recovery.

3. Referred for heavy post coital bleeding by a bright house officer at Casualty. Unable to find the bleeder by speculum by a bright house officer in ward. Bells rang. Repeated confirmed speculum revealed a small superficial 3cm superficial laceration. Packed with flavin-soaked vaginal pack. The next morning, still bleeding, pulse rate gone up and clinically mild pallor. Repacked again, sent to OT for repair. Removed the repeated packing, no more bleeding. fml. put in a 'reassurance' stitch. Unremarkable recovery.

Sex is indeed lethal. Sex kills and hurts in more way than you know.

It goes from the triggering excitement of sex or orgasm to induce a heart attack or intracranial bleed,
to a gentle good night kiss with a super-allergen on the lips OR firing away a carotid embolus,
to traumatic injuries to the genitals for both gender.
(female: vaginal laceration, male: captivating penis captivus)


If you're depressed and sad because sex (or lack of) has hurt your feeling, perhaps you should be grateful that you came out of it alive and uninjured.

So, do you have any interesting lethal sex story to share?

Interesting write-up by Chris Nickson below.

Ask not: "is this love?" Ask: "is it dangerous?"...

No, I’m not talking about revenge killings by jilted lovers, sexually transmitted infections, or the intrinsic hazards of extramarital dalliances. Love itself is dangerous. If you don’t believe me, read on to learn about all the ways amorous acts can threaten life, limb and… other body parts.

1. Neurological — benign coital headache, aneurysmal subarachnoid haemorrhage, cerebrovascular accidents
2. Urological — penile fracture, priapism, preputial tears, penile vessel rupture
3. Cardiovascular — sudden cardiac death, myocardial infarction
4. Soft tissue — soft tissue wounds, soft tissue infection
5. Immunological — local allergic reactions, anaphylaxis

Risk of sex death
Data on the risk of death during intercourse aren’t great. One retrospective study found that of people that die, about 1 in 500 were having intercourse at the time (or thereabouts). One suspects the rate could be higher: do you routinely asks the bereaved, “So, were you having sex at the time?”? The cause of death during intercourse is usually myocardial infarction, although intracerebral hemorrhage and subarachnoid hemorrhage must not be forgotten.

So far, so good. What we’ve discussed so far has been fairly standard. But seriously weird and bad things can happen during acts of love… As you’re about to find out.

Love bites
A recent report from New Zealand described a case of partial paralysis due to a ‘hickey’ or ‘love bite’. Excess suction was applied over her internal carotid artery, resulting in thrombosis…

Love allergies
Allergies and love do not mix. Steensma has described how a good night kiss, from a shrimp-eating boyfriend, nearly killed his shellfish-allergic girlfriend. Furthermore, women can actually be allergic to sex. Acute systemic hypersensitivity or localised vulvovaginitis can occur as a result of allergic reactions to semen. The sensitivity is not partner specific — condoms or abstinence are the immediate options for cure. Also, exogenous allergens (such as Brazil nuts, for example) can find their way into semen, and cause allergic reactions in receptive partners. Finally, there is an odd condition that can affect men (@DrVes told me about it) known as Postorgasmic illness syndrome (POIS). POIS is a combination of local allergic symptoms and transient flu-like illness. It may be that POIS is triggered by ejaculation and results from hypersensitivity to the male’s own semen!

Love emboli
Air emboli from sex can kill. The risk is probably higher not long after birth (especially if amphetamines are taken prior to intercourse), as it may take a while for those big uteroplacental arteries to involute after birth. However, vaginal tears from consensual intercourse, irrespective of pregnancy status, also have the potential to cause fatal air emboli. As always, any paper written by Batman is a must read:

• Batman PA, Thomlinson J, Moore VC, Sykes R. Death due to air embolism during sexual intercourse in the puerperium. Postgrad Med J. 1998 Oct;74(876):612-3. PMID: 10211360;  PMCID: PMC2361003.

Traumatic love and its complications
Vaginal injuries from consensual intercourse can lead to other problems. Pneumoperitoneum was reported following ‘conventional’ intercourse, with a 4cm vaginal laceration identified as the culprit. There was no mention of whether genital jewelry was involved. Another nasty complication from ‘normal’ coitus, as described by Ijaiya et al (2009) is rectovaginal fistula formation. The victim was later divorced by her loving husband.

Penis injuries are a bit ho-hum for the seasoned emergency physician. But, it is probably worth mentioning posterior urethral injury as a cause of hematospermia after intercourse and to provide a link to a nasty case of penile fracture associated with urtheral injury. Some blokes need target practice… or less acrobatic partners.

• Boncher NA, Vricella GJ, Jankowski JT, Ponsky LE, Cherullo EE. Penile fracture with associated urethral rupture. Case Report Med. 2010;2010:791948.  PMID: 21076536;  PMCID: PMC2975082.
• Cheng YS, Lin JS, Lin YM. Isolated posterior urethral injury: an unusual complication and presentation following male coital trauma. Asian J Androl. 2006 May;8(3):379-81. PMID: 16625291.

The mystery of penis captivus
Finally, we wouldn’t be living in the fast lane if we didn’t mention the most enigmatic of all coital conditions, penis captivus. Here are some relative modern reports from the BMJ suggesting that, yes, the condition actually does exist.

• Taylor FK. Penis captivus — did it occur? Br Med J. 1979 Oct 20;2(6196):977-8. PMID: 509182; PMCID: PMC1596579.
• Musgrave B. Penis captivus has occurred. Br Med J. 1980 Jan 5;280(6206):51. PMID: 7357285; PMCID: PMC1600543.

I have a high degree of suspicion regarding the spuriosity of the cases in Taylor’s review. One in particular stands out:

“Kisch, in his Sexual Life of Women,- speaks of “more or less credible instances of penis captivus” being on record. He mentions an account by a medical man called Davis, not otherwise identified, who was one day called to a couple found in this “most compromising position. All the endeavours of the pair thus surprised to separate proved ineffectual, and their attempts to draw apart caused them intense pain. Davis… ordered an iced douche, which, however, failed to liberate the imprisoned penis. Release was impossible until the woman had been placed under chloroform. The swollen and livid penis exhibited two strangulation-furrows.”"

A medical man called Davis? Who could that be I wonder? Perhaps an ancestor of UCEM’s PR Supervisor, the famed psychiatric surgeon Assistant Sub-Professor Egerton Y. Davis IV? Surely not? Read penis captivus and decide for yourself… As for the letter by Musgrave, one cannot help but wonder about medical doctors and their overactive imaginations. Indeed, the BMJ was clearly having a good month for letters back then — the letter immediately preceding it concerned ‘The Interesting New Zealander‘.

Conclusion
Life is a risky business. It is for the individual to decide if how they live it is worth the risk. But, what would life be without love?
Safer, is one answer.
