Urethral sponge
Theurethral spongeis a spongy cushion oftissue,found in the lowergenital areaof females, that sits against both thepubic boneandvaginalwall, and surrounds theurethra.
Functions[edit]
The urethral sponge is composed oferectile tissue;duringarousal,it becomes swollen with blood, compressing the urethra, helping, along with thepubococcygeus muscle,to preventurinationduring sexual activity.[citation needed]
Female ejaculation[edit]
Additionally, the urethral sponge contains theSkene's glands,which may be involved infemale ejaculation.
Sexual stimulation[edit]
The urethral sponge encompasses sensitivenerve endings,and can be stimulated through the front wall of thevagina.Some women experience intensepleasurefrom stimulation of the urethral sponge and others find the sensation irritating. The urethral sponge surrounds theclitoralnerve, and since the two are so closely interconnected, stimulation of the clitoris may stimulate the nerve endings of the urethral sponge and vice versa.[1]Some women enjoy therear-entry positionofsexual intercoursefor this reason, because thepenisis often angled slightly downward and can stimulate the front wall of thevagina,and in turn the urethral sponge.
Relation with the G-spot[edit]
The urethral sponge is an area in which the G-spot (Gräfenberg Spot) may be found.[1]Although the G-spot may exist, it has been doubted by various researchers. A team atThe King's Collegein London, the biggest study on the G-spot's existence thus far, and involving 1,800 women, found no proof that the G-spot exists. The authors of the study concluded that the "G-spot" may be a figment of people's imagination, which has been encouraged by magazines, sex therapists and suggestive therapeutics.[2][3]Other studies, usingultrasound,have found physiological evidence of the G-spot in women who report having orgasms during intercourse.[4][5]
