A study done at the Medical College of Georgia has found that venom from the Brazilian wandering spider contains a toxin, called Tx2-6, that causes erections. Scientists believe that combining this toxin with existing medication such as Viagra may lead to an effective treatment for erectile dysfunction.

Ultrasound of the penis and testicles is done occasionally to check for testicular size and structural abnormalities. Ultrasound with Doppler imaging can provide additional information about blood flow of the penis. Rarely, an angiogram may be performed in cases in which possible vascular surgery could be beneficial. All these mechanical methods are based on simple principles of hydraulics and mechanics and are quite reliable, but have their disadvantages. kamagra online safe buy kamagra online Erectile dysfunction, heart disease and other vascular diseases: Although ED can be caused by various conditions, about 7 in 10 cases are due to narrowing of the small arteries in the penis. This causes reduced blood flow to the penis. This is the same problem that can occur in other blood vessels. For example, narrowing of the blood vessels in the heart (the coronary arteries) is a cause of angina and other heart problems. Narrowing of blood vessels to the brain is a risk factor for having a stroke. Narrowing of blood vessels in the legs can cause peripheral vascular disease. Counselling - Sometimes couple counselling, or sex therapy is useful. These are most useful if certain psychological problems are the cause of, or the result of, ED. In some cases, sex therapy is used in addition to another treatment option. Duplex ultrasound is used to evaluate blood flow, venous leak, signs of atherosclerosis, and scarring or calcification of erectile tissue. Injecting prostaglandin, a hormone-like stimulator produced in the body, induces erection. Ultrasound is then used to see vascular dilation and measure penile blood pressure. buy viagra jelly online uk buy viagra Several other medications are being studied for treating erectile dysfunction; these include IC351 (another PDE5 inhibitor), sublingual apomorphine, and the combination of yohimbine and L-arginine. Scientists also are researching gene therapy to treat erectile dysfunction. purchase viagra online india viagra online without prescription
