Spider Venom is the New Viagra for Men

Sep 28, 2009
The venom of a deadly spider can be used for the treatment of erectile dysfunction, a new study suggests.

Scientists from the United States and Brazil revealed that men, who were bitten by the Brazilian spider, had an unusual long and painful erection. This side effect led the researchers to the development of a new Viagra for men.

During the study at the Medical College of Georgia in Augusta, the researchers isolated the toxin from the spider's venom and used a purified form of Tx2-6 on rats that had erectile dysfunction and hypertension. After that they evaluated if the toxin was present in the rats' penises and its ability to contract and relax the tissue of the penis.

The study showed that the toxin of the spider's venom boosted the level of nitric oxide, which led to improved erection.

The venom of the Brazilian wandering spiders known as (Phoneutria nigriventer) can be deadly. The scientists are working to create a drug for erectile dysfunction from the spider's venom but need further studies.

Popular drugs for erectile dysfunction such as Viagra also increase the level of nitric oxide, a chemical that plays an important role during erection. During the release of this chemical certain muscles in the penis relax and the blood flow increases. Scientists want to find how the spider's venom works to develop a new medication for this sexual dysfunction. The drug could be helpful for men, who cannot take Viagra and other drugs for medical reasons.
