VIAGRA NOW FOR WOMEN
Since Viagra works well for erectile dysfunction in men, studies were conducted to see if it could work as well on women. Cosmopolitan and Redbook magazines long have claimed that every woman should always have orgasm. Not so. It is estimated that up to 70% of women premenopausal have absent or delayed orgasm, decreased arousal and lubrication and decreased libido.
Studies showed there is significant improvement in women with new sexual complaints related to antidepressant medication. This use is an off label use of the drug Viagra and other the 5-phosphodiestrace inhibitors as vardenefil and tadafil).
These vagus inhibitors increase blood flow, engorgement, and lubrication to the genitalia, resulting in increased vaginal sensations and arousal.
The drawback: It will not work if there are spouse relationship issues, underlying depression that results in a low libido, or the woman has thyroid problems or low testosterone. It is also contraindicated in pregnancy. Contrary to expectations, Viagra decreases uterine blood flow in healthy pregnancies. It also is detrimental on the fetal blood flow and on the fetus. Pregnant women should never use it.
