==Functions==
The urethral sponge is composed of [[erectile tissue]]; during [[sexual arousal|arousal]], it becomes swollen with blood, compressing the urethra, helping, along with the [[pubococcygeus muscle]], to prevent [[urination]] during sexual activity.{{Citation needed|date=March 2018}}

{{Main article|Female ejaculation}}
Additionally, the urethral sponge contains the [[Skene's gland]]s, which may be involved in [[female ejaculation]].

===Sexual stimulation===
The urethral sponge encompasses sensitive [[nerve|nerve ending]]s, and can be [[sexual stimulation|stimulated]] through the front wall of the [[vagina]]. Some women experience intense [[pleasure]] from stimulation of the urethral sponge and others find the sensation irritating. The urethral sponge surrounds the [[Clitoris|clitoral]] nerve, and since the two are so closely interconnected, stimulation of the clitoris may stimulate the nerve endings of the urethral sponge and vice versa.<ref name="Cornforth">{{cite web|first=Tracee|last=Cornforth|title=The Clitoral Truth.

===Relation with the G-spot===
{{Main article|G-spot}}
The urethral sponge is an area in which the G-spot (Gräfenberg Spot) may be found.<ref name="Cornforth"/> Although the G-spot may exist, it has been doubted by various researchers. A team at [[King's College London|The King's College]] in 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.<ref>{{cite news| url=http://news.bbc.co.uk/1/hi/health/8439000.stm |work=[[BBC News]] | title=The G-spot 'doesn't appear to exist', say researchers | date=4 January 2010 | accessdate=2010-05-27}}</ref><ref>{{cite web |url=http://www.wiley.com/bw/journal.asp?ref=1743-6095 |archive-url=https://web.archive.org/web/20090217065942/http://www.wiley.com/bw/journal.asp?ref=1743-6095 |url-status=dead |archive-date=17 February 2009 |title=The Journal of Sexual Medicine - Wiley Online Library |publisher=[[Wiley (publisher)|Wiley]] |access-date=2013-09-07 }}</ref> Other studies, using [[ultrasound]], have found physiological evidence of the G-spot in women who report having orgasms during intercourse.<ref name="Acton">See [https://books.google.com/books?id=amNcvrLCGZEC&pg=PT98 page 98] for the 2009 King's College London's findings on the G-spot and [https://books.google.com/books?id=kP9bCflZpVkC&pg=PA145 page 145] for ultrasound/physiological material with regard to the G-spot. {{cite book|author=Ashton Acton|title=Issues in Sexuality and Sexual Behavior Research: 2011 Edition|publisher=[[ScholarlyEditions]]|year=2012|isbn=978-1464966873|url=https://books.google.com/books?id=amNcvrLCGZEC}}</ref><ref name="Aquila">{{cite journal  |vauthors=Gravina GL, Brandetti F, Martini P, etal |title=Measurement of the Thickness of the Urethrovaginal Space in Women with or without Vaginal Orgasm |journal=J Sex Med |volume= 5|issue=  3|pages=610–8|year=2008 |pmid=18221286 |doi=10.1111/j.1743-6109.2007.00739.x|hdl=2108/8798 |url=https://art.torvergata.it/bitstream/2108/8798/2/J_SEX_MED_2008.pdf |hdl-access=free }}</ref>
