Viagra is considered a type 5 phosphodiesterase inhibitor. Studies of use of Viagra for women are well under way and so far still have no results on whether it can really be administered to women. But there are results that have been successful but only in a clinical environment. There are some doctors who admitted that they have been administering Viagra to women with good results.

In a Boston University research, Viagra is being tested if it can have positive effects in the restoration of female sexual pleasure. Pfizer, the makers of Viagra, are currently conducting tests in the United Kingdom. If ever these tests are successful then further tests will be conducted to have women included in the FDA protocols approval.

Although clinical tests are being currently done by Pfizer it is still too early to see the effectiveness of this drug for women or even the side effects that will rise due to taking Viagra. Testing of the effects may not be completed soon and it might take years to even see the final results and some more, if ever the drug is proven effective, to have it approved by the FDA.

Whatever the result by Pfizer’s tests, it is a proven fact that Viagra has no effect whatsoever in the libido of a woman and the much rumored that it is an orgasm pill is outright false. If positive results come out, it would really have a great effect on women as it had on men.

A lot of researchers are quite convinced that if prostate surgery and other ailments such as diabetes can cause erectile dysfunction in men, so does high blood pressure, hysterectomies and also diabetes cause sexual dysfunctions and circulatory problems on women. Thus these ailments can also cause arousal difficulty in women.

Researchers believe that Viagra can help women as in men. When the blood vessels of the male penis become full of blood it causes an erection which is also true in women when vagina’s blood vessels become full it gets properly lubricated prior to sexual intercourse. So with this fact it might be safe to assume the Viagra might be able to help a woman achieve climax during sexual intercourse.

The main difference between male’s penis and the female’s clitoris is the lowered ability of the clitoris to attain a veno-occlusive role. To put it in laymans terms, the woman’s clitoris doesn’t have the function to attain the firmness of a penis to make it a form of structure in which to penetrate. Instead, the clitoris has the ability to become inflamed to prepare it to accept penetration.

When sexual intercourse is done, a substance called nitric oxide is freed which in turn activates the enzyme guanylate cyclase which is used to increase cyclic GMP levels. When this enzyme is released it makes the muscles spongy tissue smooth and relaxed which in turn allows the inflow of blood. Final results are increased blood flow into the vagina. An interesting fact to note is that Viagra has no effect whatsoever on the tissues that are isolated from the clitoris and the vagina.
