Venom From the Banana Spider Could Be the New Viagra

Shortness of breath, excessive salivation, tremors, and an intensely painful erection are all indications of being bitten by a highly venomous arachnid commonly known as the banana spider. So toxic is Phoneutria nigriventer, a member of the Ctenidae family of wandering spiders, that its bite has been known to kill people.

The spider is a native of the rain forests of central and South America, but it has been seen scurrying out of crates of bananas shipped to other parts of the world.

The observation that the banana spider’s bite causes priapism, prolonged erections that can damage the penis permanently, got researchers to wonder if its potent venom could be the basis of an alternate treatment for erectile dysfunction, or ED, as television commercials for Viagra, Levitra, and Cialis politely put it. About one in three men seeking a virility lift is not helped by the ED drugs currently on the market.

Brazilian and American scientists report in the current issue of the Journal of Sexual Medicine that the toxin from the Brazilian wandering spider may help treat ED in humans, if tests on elderly rodents with erectile dysfunction are anything to go by.

“Researchers from Brazil and the US extracted the toxin, called PnTx2-6, from the deadly venom and injected it into rats which had age-related erectile dysfunction,” reports the UK news site MailOnline. “They found the toxin boosted erections by triggering the release of nitric oxide, which boosts circulation in the male genitals by helping blood vessel walls relax.”

Treatment derived from the toxin may help patients who fail to respond to erectile dysfunction drugs like Viagra, which use different pathways, study co-author Kenia Nunes told NBC News.

    This acacnide is called Arana Negra in the peruvian amazon forest. It seems to work.

    Research into women’s sexual dysfunction is ongoing. One product called Bremelanotide reached final review by the FDA but the company pulled it when it was discovered that occasional side effects cause a dangerous rise in blood pressure. Current research seems concentrated on a related compound called PL-6983. What the status of that research is at this time is hard to determine.

    Eric, What things are they doing for women, specifically? Women are much more complicated than most of you men think (from my own experiences and much reading on the subject). Women have erections too. And believe me, I know when mine isn’t working! Yet the scientific community does nothing to hep women when they have a lot more sexual medical problems than men.

    @Eric – It’s typical that ED is considered a “medical condition”, but women’s inability to enjoy sex is not. Our problems are on the inside, so dryness, tissue shrinkage and pain are not considered important. Are they looking for an alternative treatment to dangerous hormone therapy for women? Maybe a female spider’s venom?

    @Bill – Just having a man present an erect phallus is not always stimulating to a woman. No – they don’t have us covered, as usual.

    Regina, you have to understand that libido and the ability to get an erection are two separate things. With that being said, there are plenty of “things” out there geared towards a woman’s pleasure. However, that is going away from this topic, which is: the vemon from this spider may be used to treat ED. Moreover, ED does not have anything to do with climaxing or enjoyment. What you are talking about is completely off topic. The topic here is talking a serious medical conditition which prevent males from getting an erection, and even when they do, these medications do not in any way bring more enjoyment or give libido to an individual. Even with viagra, a male must be turned on in order for the drug to work. Also, just because a male takes viagra, it does not mean that he will be able to even climax. Instead, it only means that he will be able to achieve an erection (thats it), the rest is up to him. In conclusion, the important fact to keep in mind here is that this article is not talking about stimulation or enjoyment. Rather, it is focusing on a medical condition.

    Regina – I believe the painful erection is actually the very thing that is “supposed” to stimulate women. Don’t worry – they’ve got you covered, babe.

    It’s great they’re working on finding solutions to a common male complaint but it seems to me women’s sexual health is never mentioned. Could these same medications improve sexual enjoyment for women as well? Women can suffer from low libido and have difficulty climaxing. It would nice if there were something which stimulated women the way these products stimulate men.
