Sex and lust will never be the same again, thanks to a wondrous 'sex chip,' which could produce a pleasure as intense and thrilling as a "delicious pastry."

Scientists are designing a 'sex chip' that will be able to enrich sex vastly by tickling pleasure centres in the brain, according to reports.

A few years ago, a similar device implanted in the brain of a woman with a low sex drive, turned her into a sexually voracious woman, informed Tipu Aziz, neurosurgery professor at the John Radcliffe hospital in Oxford.

But the sudden change was not to her liking and so the wiring in her head had to be removed, added Aziz.

The idea of such a chip has been spurred by the progress made in deep brain stimulation, with the help of implanted electrodes, used in the treatment of Parkinson's.

The area of the brain that is engaging the scientists is orbit frontal cortex -- linked with pleasure derived from eating and sex. It lies just behind the eyes.

Morten Kringelbach, of Oxford University's psychiatry department, had surveyed people who suffered from anhedonia. They could not experience pleasure from such activities. The orbitofrontal cortex could be a "new stimulation target" to help them.

Stimulating this area can produce pleasure as intense as "devouring a delicious pastry," he said.

Aziz was hopeful of a breakthrough that would make 'sex chip' a possibility within 10 years. "There is evidence that this chip will work," he added.

Unlike current procedures, which Aziz described as "intrusive and crude," that relies on a wire from a pacemaker in one's chest to the brain, he hoped emerging technology will allow wireless and self-powered brain chips.

These findings were published in the Nature Reviews Neuroscience journal.

Italian scientists have used ultrasounds to prove the mythical G-spot exists – but only for one lucky woman in four.

According to New Scientist, the researchers, at the University of L’Aquila in Italy, have discovered clear anatomical differences between women who claim to have vaginal orgasms - as opposed to clitoral - and those that don’t.

Women capable of orgasm during penetrative sex have a thicker tissue area in the region between the vagina and the urethra – meaning it’s now easy to medically tell the difference between the lucky “cans” and the “can-nots”.

Interestingly, the boffins also believe that women with the thicker tissue can be ‘taught’ to have vaginal orgasms, if they can’t already.

Although the ultrasound scans showed only eight in 30 women had a G-spot, only five of those reported vaginal orgasms.

But after receiving advice on the G-spot’s location, two of the remaining three were able to hit the big O.

The research team is now investigating if there is a link between comparatively hairy women and the G-spot, with testosterone thought to be responsible for the thicker tissue.

But it’s not all bad news for thay majority of women born without the anatomical blessing, with scientists confident it’s conceivable to “grow” a G-spot through practise.

“I fully agree that the use makes the organ,” said head researcher Emmanuele Jannini.

“I do expect an increase with frequent use.”
