View of the ( intravaginal ) periurethal cavernous tissue. The clitoris is at the bottom of the picture. Above it the urethral opening, Meatus urethrae externus , it is closed and visible as a small elevation. This is followed by u. a. also the "G-Zone", as a small trough-shaped depression.

The Graefenberg zone , or G-zone , G-spot or G-spot , is described as an erogenous zone in the vagina . It is named after Ernst Graefenberg , a German doctor who wrote in an article in 1950 about an "erogenous zone in the anterior vaginal wall, along the urethra that swells when sexually stimulated ". The Graefenberg zone as an anatomically clearly circumscribed and regular structure is scientifically questioned today and is not listed by most anatomy textbooks. The Graefenberg zone and also the A point were suspected to be in the area of ​​the so-called Halban's fascia or septum vesicovaginale , which is located between the vagina and the urinary bladder. For some women , their stimulation leads to an orgasm very quickly , but for others it is little or no arousing. However, the G-spot only becomes active as an erogenous zone after a certain level of arousal (e.g. achieved through clitoral stimulation). Some studies also suggest that G-spot stimulation is important in the birth process .

History

Reinier de Graaf (1672) was the first to describe female ejaculation and referred to a particularly sensitive zone in the anterior, ventral vaginal wall , which he associated with the man's prostate and which was later discovered by the German gynecologist Ernst Graefenberg in his search for the vaginal pleasure center of women was rediscovered as the Graefenberg zone. The English obstetrician and doctor William Smellie also mentioned female ejaculation during coitus.

anatomy

The zone is about two inches from the entrance to the vagina on the front wall of the vagina. It has the shape of a flattened hemisphere about two centimeters in diameter and a depression in the middle. According to Graefenberg , the feminine prostate is located in the area of ​​the G-Zone , the glandular tissue of which produces secretions when sexually stimulated and can subsequently lead to female ejaculation , a multi-phase pulsating discharge. These are the so-called paraurethral glands , because they lie around (para) the urethra (urethra). Because they were carefully examined by the gynecologist Alexander Skene , they are also called Skene's glands .

A characteristic of the G-spot is that the tissue here feels rough, ribbed, or hard, while the rest of the vaginal wall is smooth. The shape, size and sensitivity can vary widely. The type of stimulation required depends not only on the physiological body structure , morphology and anatomy , but also on the reaction templates learned.

For women, the stimulation of the clitoris (also known as the "C-point") plays an essential role in achieving orgasm . Stimulation of other erogenous zones in addition to the G-spot, such as the A -spot or the tissue around the female urethral orifice ("U-spot"), also increases pleasure. The orgasm achieved solely by stimulating the erogenous zones within the vagina is called a "vaginal orgasm". It is controversial whether it differs from the "clitoral orgasm".

The G-spot is part of a corpus cavernosum urethrae , the corpus cavernosum urethrae , which surrounds the female urethra , to which, as an intravaginal continuation, the Halban'schen fascia , the Graefenberg zone and the anterior fornix erogenous zone (AFE zone) are included as additional cavernous tissue.

The nerve supply to the female urethra and the surrounding erectile tissue is provided by the vesical plexus (part of the inferior hypogastric plexus ) and the pudendal nerve . Visceral afferents from the urethra run in the splanchnic pelvic nerves.

criticism

The view that the G-spot is an anatomically clearly defined and regular structure is discussed by scientists. The Graefenberg zone has not found its way into most anatomy textbooks.

Terence M. Hines, a psychologist at New York's Pace University, concludes in an article titled The G-Spot: a modern gynecological myth , published in 2001 in the American Journal of Obstetics and Gynaecology :

The evidence is far too weak to support the reality of the G-spot. Specifically, anecdotal observations and case studies made on the basis of a tiny number of subjects are not supported by subsequent anatomic and biochemical studies.

“The evidence for the existence of the G-spot is far too weak. In particular, individual observations and case studies were made with a small number of people that were subsequently not confirmed by anatomical and biochemical studies. "

For example, a study by King's College of London University on twins comes to the following conclusion:

“The G-spot myth is just a product of the media and sex therapists. If so, it only exists in the head, depending on the woman's character. And that has nothing to do with diet or exercise. "

- Tim Spector

For a long time, the existence of the G-spot served as an important reason for vaginal orgasm as the only justifiable one, since it should be achieved solely by stimulating the penis during sexual intercourse. Contrary to previous assumptions, current scientific studies suggest that 70 to 80 percent of women can achieve orgasm solely by stimulating the clitoris. It can be assumed from an empirical point of view that the majority of women cannot orgasm simply by penetrating the penis into the vagina. Orgasms triggered by clitoral stimulation are easier to achieve because the glans clitoridis has more sensory nerve endings than any other part of the human body. The acceptance of the clitoral orgasm and the explicit external stimulation was an important milestone in the emancipation of women.

G-spot amplification

With G-Spot amplification (also G-Spot augmentation or G-Shot ), the G-spot is enlarged and sensitized with collagen in order to temporarily increase the sensation of pleasure in sexually active women. The effect is said to last six months. The benefits have not been studied, however, and the procedure has risks such as: B. Infections , dyspareunia or scarring. As with all interventions that are not medically necessary, but purely aesthetic or sexual reasons, the consent of the legal guardian should be available for under 16-year-olds.

Risk-free alternative is wearing pleasure balls ( Loveballs ) that strengthen the pelvic floor muscles and also the U. a. To increase orgasm ability.

Pudental, Pelvic, Hypogastric, intercostal and Vagus nerves constitute the main nerve network system. Also there are at least two Oxytocin pathway systems, whereas Oxytocin works as a neurotransmitter and as a hormone, separately. During expanded orgasms and ESR orgasms, more than one 'orgasm reflex arch pathway' is activated and trigger an expanded orgasm, while many others contribute to the formation of an EO or ESR orgasms.
