Scientists say a synthetic compound derived from Brazilian wandering spider venom could treat people with erectile dysfunction for whom drugs like Viagra don't work.
A spider whose venom triggers prolonged and painful erections may hold the key to more inclusive treatments for erectile dysfunction, scientists in Brazil report.
Among other symptoms — including increased blood pressure, nausea, abdominal cramps and convulsions — this spider's bite can cause a"prolonged and painful erection, which can lead to necrosis of the penis," meaning death of its tissues, Maria Elena de Lima, a professor of biomedicine and medicine at the Santa Casa Belo Horizonte hospital in Brazil who is leading the research, said in a translated statement.
While erectile dysfunction treatments are generally thought safe for people with high blood pressure who are otherwise healthy, they are not suitable for patients who, in addition to high blood pressure, also have urinary tract problems. The drugs may also pose risks for people with severe heart or liver problems.
The molecule, which scientists formulated into a gel and applied to the rodents' groins, triggered erections in the animals. Like the spider's venom, BZ371A triggers the release of nitric oxide, which boosts blood flow to the genital area; Viagra, by comparison, blocks an enzyme to make the penis more sensitive to nitric oxide released by the body.
