How Does Viagra Work

Viagra works by blocking an enzyme that acts as an inhibitor of blood flow. In men, this can cause penile tissue to swell. When a man takes Viagra, there is an increase in blood flow to the genital areas, which thus helps to treat erectile dysfunction or impotence in men.

The same enzyme inhibitor affecting male sexual dysfunction influences pelvic blood flow in women. The Viagra research team attempted to find a link between arousal in women and pelvic blood flow in the early stages of trials. However, this attempt failed, and some researchers even suggested that genital arousal in women does not necessarily produce sexual desire in women as it typically does in men. Women may define sexual arousal based on mental and emotional, as well as biological factors.

According to some of the researchers working on the Viagra team, Viagra for women or a Viagra alternative may help women facing sexual dysfunction due to side effects of other medication. In cases where sexual desire is inhibited due to emotional or psychological factors, a female Viagra solution may not be applicable.
