In 1944 a German obstetrician, Ernst Gräfenberg, first associated the stimulation of the spot (which he named "G" from the initial of his last name) with the expulsion of fluid from the urethra during sexual arousal. After many years of research, in 1950 he disclosed his conclusions in his article "The Role of the Urethra in Female Orgasm": "If there is the opportunity to observe the orgasm of such women, one can see that large quantities of a clear, transparent fluid are expelled not from the vulva, but out of the urethra in gushes. At first, I thought that the bladder sphincter had become defective by the intensity of the orgasm, since involuntary expulsion of urine is reported in sex literature. But in the cases observed by us, the fluid was examined and it had no urinary character. I am inclined to believe that 'urine' reported to be expelled during female orgasm is not urine, but secretions of the intraurethral glands correlated with the erotogenic zone along the urethra in the anterior vaginal wall. Moreover, the profuse secretions coming out with the orgasm have no lubricating significance, otherwise they would be produced at the beginning of intercourse and not at the peak of orgasm. Every woman has a G-Spot, and it is very important that men take the time to explore this highly erogenous zone.
