The ‘G-spot’ may not really exist, researchers say.
Portuguese scientists reviewed the evidence on the elusive region, which is said to give women powerful orgasms when stimulated.
Many previous studies agreed it existed, but experts behind the new study failed to pinpoint its location, size or nature.
Writing in the journal Sexual Medicine, the team said: ‘Therefore, we must conclude that its existence remains to be scientifically proven.’
Researchers described the G-spot as being like Atlantis, a mythical city written about by Greek philosopher Plato.
The G-spot, thought to be an erogenous area in the vaginal wall, has been discussed in literature since the 11th century.
But despite widespread acceptance, a deluge of studies over the past few decades have failed to pinpoint whether it even exists.
Researchers have previously described the anatomical evidence of a G-spot ‘scant, insufficient and weak’.
But others have claimed such findings show ‘a lack of respect for what women say’, because a majority have reported having G-spot in a series of studies.
Medics at five hospitals in Portugal and one in Italy examined 32 studies carried out dating back to the 1980s to determine whether the G-spot existed.
The criteria for identifying the elusive region varied between the studies, but could include a more sensitive area and bulging or swelling upon stimulation.
The majority of women who participated in six questionnaire studies (62.9 per cent) claimed to have a G-spot.
nd nearly three quarters (72.6 per cent) believed it was associated with having an orgasm.
Researchers said the findings ‘clearly show’ most women believe the G-spot exists, but ‘this belief may be biased by the current assumption that it does exist’.
The G-spot was identified among the the majority (55.4 per cent) of the 1,842 women who participated in seven clinical studies, which involved investigators manually stimulating participants or using a vibrator.
But among these seven papers, there were mixed results. It was identified among all women in two of the studies and none of the women in another two similar projects.
And even among nine medical imaging studies — which take detailed pictures of the inside of the body through ultrasounds or MRI scans — had contradictory results.
In nine separate anatomical studies, one author claimed to be able to systematically identify the G-spot, while another group did not find it at all.
And one neurophysiological study evaluated the electrical activity of the vagina through specialist tools and found that it increased in response to pressure, suggesting the mystery region did exist in some form.
Dr Pedro Vieira Baptista, a gynaecologist at Hospital Lusíadas in Porto, and his colleagues noted there was biases among the studies, such as some only including women who struggle to have an orgasm or involving an investigator manually stimulating a participant, which made it less likely for women to have a sexual response.
