the urethral sponge is an area in which the g-spot (gräfenberg spot) may be found. although the g-spot may exist, it has been doubted by some researchers. a team at the king's college of london, in a big study on the g-spot's existence in recent years, and having 1,800 women, found no proof that the g-spot exists. the authors of the study had stated that the "g-spot" may be a figment (thought) of people's imagination, which has been encouraged by magazines, sex therapists and suggestive therapeutics. however, some other studies, using ultrasound, have found physiological evidence of the g-spot in women who report having orgasms during intercourse.
