A spray, initially sold as a cure for men's erectile problems, can improve sex lives of millions of women, who regularly have to fake orgasms, say its promoters.
Jack Vaisman, the chief executive of Advanced Medical Institute, has said that the "nasal spray technology" can boost ladies' flagging sex-drive.
Costing 4000 pounds for men, the treatments would now be marketed to women using the slogan: "Stop faking, get real."
However, the product has already raised concerns among doctors, who have doubts about the erectile treatment.
"Most sexual dysfunction in women is due to pelvic surgery or primarily psychological issues," The Sydney Morning Herald quoted David Malouf, president of the Urological Society of Australia and New Zealand, as saying.
He added: "There's very little evidence that these agents will have any useful role in managing dysfunction in women."
Vaisman, however, said that the spray stimulated the production of dopamine.
"If we can give men an erection - and we can - then practically with the same medication [we can help women]. Why not help?" he said.
