I am amazed at the things men will endure in order to have an erection!
Forget about powdered rhino horn and tiger penis, there is a real animal-based remedy for male impotence: the venom of the Brazilian wandering spider, Phoneutria nigriventer (pictured, image: BBC News).
Even though the venom of this spider is known to be deadly in some cases, Brazilian and US researchers interviewed men who claimed their sex lives had improved after a spider attack.
The toxin, Tx2-6, causes erections. It has been tested successfully on other animals.
Scientists think that combining Tx2-6 with an existing drug for erectile dysfunction, such as Viagra, Cialis or Levtra, could produce better results.
Is this why Mary Jane goes out with Peter Parker!?
Sounds like a perfect Darwinian solution!
