In a 1981 published case study of one woman, it was reported that stimulation of the anterior vaginal wall made the area grow by fifty percent and that self-reported levels of arousal/orgasm were "deeper" when the G-Spot was stimulated.[15] Another study, in 1983, examined eleven women by palpating the entire vagina in a clockwise fashion, and reported a specific response to stimulation of the anterior vaginal wall in four of the women.[24] Researchers at the University of L'Aquila have found, using ultrasonography, that women who experience vaginal orgasms are statistically more likely to have thicker tissue in the anterior vaginal wall.[8] The researchers believe these findings make it possible for women to have a rapid test to confirm whether or not they have a G-Spot.[25] A French study in late 2009 examined a small number of women with ultrasound as they had intercourse. By examining changes in the vagina, the research team found physiological evidence of the G-Spot.[6] Though the hypothesis has been challenged (see below), there is some research suggesting that G-Spot and clitoral orgasms are of the same origin. Masters and Johnson were the first to determine that the clitoral structures surround and extend along and within the labia. Upon studying women's sexual response cycle to different stimulation, they observed that both clitoral and vaginal orgasms had the same stages of physical response, and found that the majority of their subjects could only achieve clitoral orgasms, while a minority achieved vaginal orgasms. On this basis, Masters and Johnson argued that clitoral stimulation is the source of both kinds of orgasms,[26][27][28] reasoning that the clitoris is stimulated during penetration by friction against its hood.[29] Professor of genetic epidemiology, Tim Spector, who co-authored research questioning the existence of the G-Spot, finalized in 2009, hypothesizes thicker tissue in the G-Spot area may be part of the clitoris and is not a separate erogenous zone.[11][13] Supporting Spector's conclusion is a study published in 2005 which investigates the size of the clitoris it suggests that clitoral tissue extends into the anterior wall of the vagina. The main researcher of the studies, Australian urologist Helen O'Connell, asserts that this interconnected relationship is the physiological explanation for the conjectured G-Spot and experience of vaginal orgasms, taking into account the stimulation of the internal parts of the clitoris during vaginal penetration. While using MRI technology, O'Connell noted a direct relationship between the legs or roots of the clitoris and the erectile tissue of the "clitoral bulbs" and corpora, and the distal urethra and vagina. "The vaginal wall is, in fact, the clitoris," said O'Connell. "If you lift the skin off the vagina on the side walls, you get the bulbs of the clitoris triangular, crescental masses of erectile tissue."[9] O'Connell et al., who performed dissections on the female genitals of cadavers and used photography to map the structure of nerves in the clitoris, were already aware that the clitoris is more than just its glans and asserted in 1998 that there is more erectile tissue associated with the clitoris than is generally described in anatomical textbooks.[27][18] They concluded that some females have more extensive clitoral tissues and nerves than others, especially having observed this in young cadavers as compared to elderly ones,[27][18] and therefore whereas the majority of females can only achieve orgasm by direct stimulation of the external parts of the clitoris, the stimulation of the more generalized tissues of the clitoris via intercourse may be sufficient for others.[9] French researchers Odile Buisson and Pierre Foldès reported similar findings to that of O'Connell's. In 2008, they published the first complete 3D sonography of the stimulated clitoris, and republished it in 2009 with new research, demonstrating the ways in which erectile tissue of the clitoris engorges and surrounds the vagina. On the basis of this research, they argued that women may be able to achieve vaginal orgasm via stimulation of the G-Spot because the highly innervated clitoris is pulled closely to the anterior wall of the vagina when the woman is sexually aroused and during vaginal penetration. They assert that since the front wall of the vagina is inextricably linked with the internal parts of the clitoris, stimulating the vagina without activating the clitoris may be next to impossible.[30][31][32] In their 2009 published study, the "coronal planes during perineal contraction and finger penetration demonstrated a close relationship between the root of the clitoris and the anterior vaginal wall". Buisson and Foldès suggested "that the special sensitivity of the lower anterior vaginal wall could be explained by pressure and movement of clitoris's root during a vaginal penetration and subsequent perineal contraction".[32] In 2011, researcher Adam Ostrzenski claimed to have found the first evidence of G-Spot anatomical structures by dissecting a cadaver in Poland. Between the fifth and sixth layer of the vaginal wall, there were grape-like clusters Ostrzenski believes are erectile tissue that would function as a G-Spot. The research was published in The Journal of Sexual Medicine in 2012. Critics of Ostrzenski's claim note that he provided no evidence that his sample consists of nerve endings, that the structures play a role in arousal, or that they would be in one specific area. Ostrzenski said that part of the reason he did not detail a precise type of tissue and how it works is because the Polish regulations that govern dissection of fresh cadavers prevented him from taking samples for histological testing. He said that he is not suggesting that the G-Spot he reports to have found will be in the same place, or have the same effect, for every woman.[33]
