'''Retrograde ejaculation''' occurs when [[semen]] which would be [[ejaculation|ejaculated]] via the [[urethra]] is redirected to the [[urinary bladder]]. Normally, the [[Urethral sphincters|sphincter of the bladder]] contracts before ejaculation, inhibiting urination and preventing a reflux of semen into the bladder. The semen is forced to exit via the urethra, the path of least resistance. When the bladder sphincter does not function properly, retrograde ejaculation may occur. It can also be induced deliberately as a primitive form of [[male birth control]] (known as ''coitus saxonicus'') or as part of certain [[alternative medicine]] practices. The retrograde-ejaculated semen is [[Excretion|excreted]] from the bladder during the next [[urination]].<ref name=Mayo>{{cite web |url=http://www.mayoclinic.com/health/retrograde-ejaculation/DS00913 |title=Retrograde ejaculation - MayoClinic.com }}</ref>
