Jellyfish toxin produces erections
I suppose we are all going to be barraged with spam for "Miracle irukandji" soon.
The sting from an irukandji tentacle can cause irukandji syndrome, entailing severe pain, anxiety, paralysis and a potentially fatal rise in blood pressure. Researchers have found that one rare species also causes an extra symptom of prolonged erections in male victims.
Of course, if you read the detailed possible side effects for Viagra, they sound about the same. Maybe that’s where they get it?
