The G spot, also called the Gräfenberg spot (for German gynecologist Ernst Gräfenberg), is characterized as an erogenous area of the vagina that, when stimulated, may lead to strong sexual arousal, powerful orgasms and potential female ejaculation. It is typically reported to be located up the front (anterior) vaginal wall between the vaginal opening and the urethra and is a sensitive area that may be part of the female prostate. The existence of the G spot has not been proven, nor has the source of female ejaculation. Although the G spot has been studied since the 1940s, The G spot may be an extension of the clitoris, which together may be the cause of orgasms experienced vaginally. Sexologists and other researchers are concerned that women may consider themselves to be dysfunctional if they do not experience G spot stimulation, and emphasize that not experiencing it is normal. The location of the G spot is typically reported as being about 50 to 80 mm (2 to 3 in) inside the vagina, on the front wall. For some women, stimulating this area creates a more intense orgasm than clitoral stimulation. Attempting to stimulate the area through sexual penetration, especially in the missionary position, is difficult because of the particular angle of penetration required.]] Women usually need direct clitoral stimulation in order to orgasm, and G spot stimulation may be best achieved by using both manual stimulation and vaginal penetration. Sex toys are available for G spot stimulation. One common sex toy is the specially designed G spot vibrator, which is a phallic vibrator that has a curved tip and attempts to make G spot stimulation easy. G spot vibrators are made from the same materials as regular vibrators, ranging from hard plastic, rubber, silicone, jelly, or any combination of them. 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, concluding that the area is the G spot. In a 1990 study, an anonymous questionnaire was distributed to 2,350 professional women in the United States and Canada with a subsequent 55% return rate. Of these respondents, 40% reported having a fluid release (ejaculation) at the moment of orgasm, and 82% of the women who reported the sensitive area (Gräfenberg spot) also reported ejaculation with their orgasms. Several variables were associated with this perceived existence of female ejaculation. Some research suggests 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, reasoning that the clitoris is stimulated during penetration by friction against its hood. Researchers at the University of L'Aquila, using ultrasonography, presented evidence that women who experience vaginal orgasms are statistically more likely to have thicker tissue in the anterior vaginal wall. Professor of genetic epidemiology, Tim Spector, who co authored research questioning the existence of the G spot and finalized it in 2009, also hypothesizes thicker tissue in the G spot area; he states that this tissue may be part of the clitoris and is not a separate erogenous zone. 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." 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". it has been unofficially called the male G spot because it can also be used as an erogenous zone. Regnier de Graaf, in 1672, observed that the secretions (female ejaculation) by the erogenous zone in the vagina lubricate "in agreeable fashion during coitus". Modern scientific hypotheses linking G spot sensitivity with female ejaculation led to the idea that non urine female ejaculate may originate from the Skene's gland, with the Skene's gland and male prostate acting similarly in terms of prostate specific antigen and prostate specific acid phosphatase studies, which led to a trend of calling the Skene's glands the female prostate. Because of these factors, it has been argued that the G spot is a system of glands and ducts located within the anterior (front) wall of the vagina.

G spot amplification (also called G spot augmentation or the G Shot) is a procedure intended to temporarily increase pleasure in sexually active women with normal sexual function, focusing on increasing the size and sensitivity of the G spot. G spot amplification is performed by attempting to locate the G spot and noting measurements for future reference. After numbing the area with a local anesthetic, human engineered collagen is then injected directly under the mucosa in the area the G spot is concluded to be in. A position paper published by the American College of Obstetricians and Gynecologists in 2007 warns that there is no valid medical reason to perform the procedure, which is not considered routine or accepted by the College; and it has not been proven to be safe or effective. The potential risks include sexual dysfunction, infection, altered sensation, dyspareunia, adhesions and scarring. The procedure is also not approved by the Food and Drug Administration or the American Medical Association, and no peer reviewed studies have been accepted to account for either safety or effectiveness of this treatment.

In addition to general skepticism among gynecologists, sexologists and other researchers that the G spot exists, She stated that one of the reasons for the research was to remove feelings of "inadequacy or underachievement" for women who feared they lacked a G spot. Researcher Beverly Whipple dismissed the findings, commenting that twins have different sexual partners and techniques, and that the study did not properly account for lesbian or bisexual women. Petra Boynton, a British scientist who has written extensively on the G spot debate, is also concerned about the promotion of the G spot leading women to feel "dysfunctional" if they do not experience it. "We're all different. Some women will have a certain area within the vagina which will be very sensitive, and some won't — but they won't necessarily be in the area called the G spot," she stated. "If a woman spends all her time worrying about whether she is normal, or has a G spot or not, she will focus on just one area, and ignore everything else. It's telling people that there is a single, best way to have sex, which isn't the right thing to do."

G spot proponents are criticized for giving too much credence to anecdotal evidence, and for questionable investigative methods; for instance, the studies which have yielded positive evidence for a precisely located G spot involve small participant samples. some scientific examinations of vaginal wall innervation have shown no single area with a greater density of nerve endings. The urethral sponge, however, which is also hypothesized as the G spot, contains sensitive nerve endings and erectile tissue. While G spot opponents argue that because there are very few tactile nerve endings in the vagina and that therefore the G spot cannot exist, G spot proponents argue that vaginal orgasms rely on pressure sensitive nerves. Puppo's belief that there is no anatomical relationship between the vagina and clitoris is contrasted by the general belief among researchers that vaginal orgasms are the result of clitoral stimulation; they maintain that clitoral tissue extends, or is at least likely stimulated by the clitoral bulbs, even in the area most commonly reported to be the G spot. "My view is that the G spot is really just the extension of the clitoris on the inside of the vagina, analogous to the base of the male penis", said researcher Amichai Kilchevsky. Because female fetal development is the "default" direction of fetal development in the absence of substantial exposure to male hormones and therefore the penis is essentially a clitoris enlarged by such hormones, Kilchevsky believes that there is no evolutionary reason why females would have two separate structures capable of producing orgasms and blames the porn industry and "G spot promoters" for "encouraging the myth" of a distinct G spot. Ian Kerner stated that the G spot may be "nothing more than the roots of the clitoris crisscrossing the urethral sponge". "I think that the bulk of the evidence shows that the G spot is not a particular thing," stated Barry Komisaruk, head of the research findings. "It's not like saying, 'What is the thyroid gland?' The G spot is more of a thing like New York City is a thing. It's a region, it's a convergence of many different structures".

The release of fluids had been seen by medical practitioners as beneficial to health. Within this context, various methods were used over the centuries to release "female seed" (via vaginal lubrication or female ejaculation) as a treatment for suffocation ex semine retento (suffocation of the womb), female hysteria or green sickness. Methods included a midwife rubbing the walls of the vagina or insertion of the penis or penis shaped objects into the vagina. In the book History of V, pl lists old terms for what she believes refer to the female prostate (the Skene's gland), including the little stream, the black pearl and palace of yin in China, the skin of the earthworm in Japan, and saspanda nadi in the India sex manual Ananga Ranga. The 17th century Dutch physician Regnier de Graaf described female ejaculation and referred to an erogenous zone in the vagina that he linked as homologous with the male prostate; this zone was later reported by the German gynecologist Ernst Gräfenberg. Coinage of the term G spot has been credited to Addiego et al. in 1981, named after Gräfenberg, and to Alice Kahn Ladas and Beverly Whipple et al. in 1982. Gräfenberg's 1940s research, however, was dedicated to urethral stimulation; Gräfenberg stated, "An erotic zone always could be demonstrated on the anterior wall of the vagina along the course of the urethra". The concept of the G spot entered popular culture with the 1982 publication of The G Spot and Other Recent Discoveries About Human Sexuality by Ladas, Whipple and Perry, some of them denied its existence as the absence of arousal made it less likely to observe, and autopsy studies did not report it.
