To have more sex is one thing.

To have it with a greatly "improved" partner is even more appealing...

Not to mention that the sexier a women feels, the better sexual confidence she will have ...

Now, a new sex pill that is going to be developed not only boosts a woman's sex drive, but it also cuts off her food drive.

The chemical, type 2 Gonadotropin-releasing hormone, was tested so far just on shrews and marmoset monkeys, and being applied on humans could take up to almost 10 years.

Professor Robert Millar discovered the double benefit while developing a hormone to treat loss of libido, a problem which affects millions of women.

The chemical was checked initially just for sex drive. But the researchers noticed also the decreased interest in food, besides typical mating behavior. Female musk shrews and marmosets normally display this behavior just when they are ovulating. Shrew females started "rump presentation and tail wagging", while the monkeys displayed "tongue flicking and eyebrow raising", said Millar.

The daily food intake was reduced by a third. "This hormone is distributed in the brain in areas that we suspect affect reproductive behavior," said Millar, director of the Human Reproductive Sciences Unit at the Medical Research Council in Edinburgh.

"It is considered a major pharmaceutical endeavor to address the area of libido. So the next stage is to produce a drug that simulates the actions of this hormone. It is most likely that we will do it in partnership with a pharmaceutical firm. It could be available to women within ten years."

This could be the first "lifestyle drug" that works on both the sex drive and the appetite. Anyhow, the appetite side would be the most appreciated by women. "Some women have problems specific to libido, but often if they go off sex, it's more to do with their relationship than with their level of libido," said Dr Lesley Perman-Kerr, a chartered psychologist.

"In my experience, when couples come to me and they are not having sex, the last thing they want to do is examine their relationship. So it may be that women would take the pill when they have a good sex life and they want to enhance it." he added.
