    Ultrasound nails location of the elusive G spot

    Ultrasound nails location of the elusive G spot
    FOR women, it is supposed to trigger one of the most intense orgasms imaginable, with waves of pleasure spreading out across the whole body. If the "G spot orgasm" seems semi-mythical, however, that's because there has been scant evidence of its existence.

    Now for the first time gynaecological scans have revealed clear anatomical differences between women who claim to experience vaginal orgasms involving a G spot and those who don't. It might mean that there is a G spot, after all. What's more, a simple test could tell you if it's time to give up the hunt, or if your partner just needs to try harder.

    "For the first time it is possible to determine by a simple, rapid and inexpensive method if a woman has a G spot or not," says Emmanuele Jannini at the University of L'Aquila in Italy, who carried out the research.

    Jannini had already found biochemical markers relating to heightened sexual function in tissue between the vagina and urethra, where the G spot is said to be located. The markers include PDES - an enzyme that processes the nitric oxide responsible for triggering male erections (see New Scientist, 6 July 2002, p 23).

    However, the team had been unable to link the presence of these markers to the ability to experience a vaginal orgasm - that is, an orgasm triggered by stimulation of the front vaginal wall without any simultaneous stimulation of the clitoris.

    So Jannini's team took a different approach, and used vaginal ultrasound to scan the entire urethrovaginal space - the area of tissue between the vagina and urethra thought to house the G spot (see Diagram). The team scanned nine women who said they had vaginal orgasms and 11 who said they didn't. They found that tissue in the urethrovaginal space was thicker in the first group of women (Journal of Sexual Medicine, DOI: 10.1111/j.1743-6109.2007.00739.x). This means, says Jannini, that "women without any visible evidence of a G spot cannot have a vaginal orgasm".

    Other researchers question whether what Jannini says is the G spot is a distinct structure or the internal part of the clitoris. The urethrovaginal space is rich in blood vessels, glands, muscle fibres, nerves, and - in some women - a remnant of the embryological prostate called the Skene's glands. Some researchers have suggested that the Skene's glands are involved in triggering vaginal orgasms and, more controversially, enable a small number of women to ejaculate (see "Can women ejaculate or not?").

    "The authors found a thicker vaginal wall near the urethra and hypothesise this may be related to the presence of the controversial G spot," says Tim Spector at St Thomas' Hospital in London. "However, many other explanations are possible - such as the actual size of the clitoris, which, although not measured in this study - appears highly variable."
