Viagra flops for brainy women

Women achieve the most sexual satisfaction through the stimulation of their brain, scientists have concluded.

After tests involving 3,000 women since 1996, researchers at Pfizer, the makers of Viagra, are ending efforts to use the anti-impotency drug to treat female sexual problems. Mitra Boolel, who is in charge of the company's sex-research team, explained that his findings show ed that arousal and desire were experienced very differently by men and women. A woman's arousal is triggered by complex combinations of emotional, intellectual and relationship-based factors, while a man's is a simple physical response.

Dr Boolel said: "There's a disconnect in many women between genital changes and mental changes. Men consistently get erections in the presence of naked women and want to have sex. With women, things depend on a myriad of factors." Dr Boolel added that "the brain is the crucial sexual organ in a woman". The company has not given up hope of developing an alternative to Viagra for women, and the team is focusing on finding drugs that affect brain chemistry.

Kathy Lette, the Australian author said: "To please a woman in bed, all a man has to do is a poetry course. They also have to learn that the Karma Sutra is not an Indian takeaway and that the mutual orgasm is not an insurance company."
