Viagra can improve the love life of men, but a recent study from Columbia Medical School in New York shows that the best it does for women is increase vaginal lubrication.

One out of four women reported improvement in clitoral sensitivity and vaginal lubrication, but no enhancement of orgasm. One in five complained of discomfort when their clitoris was touched. A few reported dizziness, headache and upset stomach. The doctors felt that except for vaginal lubrication and clitoral sensitivity, Viagra did not improved the women's sexuality.

Viagra opens blood vessels to the penis, distending the balloons that cause an erection. Women may not benefit from increased blood flow to the clitoris, but vaginal secretions that lubricate the vagina during lovemaking come from the blood, and increasing blood flow to the vagina increases secretions. Viagra is relatively safe and does not cause heart attacks, but it should not be given with some drugs that are used to treat high blood pressure.
