Am G-Spot befinden sich die Skene'schen Drüsen, welche der Prostata entsprechen und die enthalten bei manchen Frauen PDE5 - darauf wirkt dann Viagra - je größer der spot, umso besser und umso besser ist der vaginale Orgasmus.
https://www.newscientist.com/article/dn ... he-g-spot/The term G spot, coined by Ernest Gräfenberg in 1950, refers to an area a few centimetres up inside the vagina on the side closest to a woman’s stomach (see diagram). Buried in the flesh here are the Skene’s glands, the female equivalent of the prostate gland.
In men, the prostate produces the watery component of semen. In women, Skene’s glands are also thought to produce a watery substance that may explain female “ejaculation”. The tissue surrounding these glands, which includes the part of the clitoris that reaches up inside the vagina, swells with blood during sexual arousal. And there’s some evidence that nerves in the area produce an orgasm different to one produced by clitoral stimulation.
Nevertheless, there is still debate about whether the G spot even exists. “Not everyone has accepted this yet,” says Beverly Whipple, a neurophysiologist who co-wrote a book about the G spot in the 1980s. So Emmanuele Jannini of the University of Aquila, Italy, and his team decided to look for biochemical markers of sexual function in the area where the G spot is meant to be. They picked PDE5, an enzyme that chews up the nitric oxide that triggers erections. Viagra works by blocking PDE5.
