Common use viagra videos leukaemia (cancer of the blood cells)
Viagra (sildenafil) and the other drugs for erectile dysfunction,Levitra (vardenafil) and Cialis (tadalafil), work by inhibiting the chemical phosphodiesterase, which leads to an increase in the effect of nitric oxide. Nitric oxide allows the smooth muscles inside the penis to relax, promoting more blood flow to the area during sexual arousal or stimulation. Through this action, the drugs work to fix a functional problem. The use of Viagra-like drugs in women is not so straightforward and a similar treatment does not exist for women. Viagra may help women who report having difficulties with lubrication because the increase in blood flow to the female genitals would subsequently increase lubrication. However, this use is not approved by the U.S. Food and Drug Administration. In addition, in most cases the problem for women is not with physical arousal but rather a lack of sexual desire. Scientists are looking at other drugs in women with sexual dysfunction who either say they're uninterested in sex or that sex provides little pleasure.
