Spider venom can cause four-hour erections 'the new Viagra'

Silk and Venom: Searching for a Dangerous SpiderSpider venom can cause four-hour erections 'the new Viagra' | Mail Online: "In her study published in the Journal of Sexual Medicine, Dr. Nunes’ experiment managed to give erection-challenged rats with high blood pressure a bit of a boost.

A peptide called PnTx2-6 was given to the flaccid rats, who achieved side-effect free erections.

Dr. Nunes said: ‘We found the toxin responsible [for the erections] and performed experiments using hypertensive rats which have severe erectile dysfunction. The toxin was able to normalise the erectile dysfunction in these animals.’

The spider’s toxin worked in a different way to drugs such as Viagra though and Nunes told MSNBC: ‘This is good because we know that some patients don’t respond to the conventional therapy.

‘This could be an optional treatment for them.’

She is also hopeful that the toxin could help female sexual dysfunction, but has not yet studied this.

The Brazilian wandering spider, which has a leg span of over four inches, has already been found in some American and Canadian supermarkets but is normally found in tropical banana plantations.

According to the curator of arachnids at the University of Washington’s Burke Museum, Rod Crawford, only 10 humans out of 7,000 have died from its bite."
