Editing Retrograde ejaculation (section)

==Intentional induction==
Retrograde ejaculation can be deliberately induced by squeezing the urethra at the base or applying pressure to the [[perineum]] during orgasm. The retrograde-ejaculated sperm goes into the bladder and is excreted with the next urination.<ref name=Mayo/>

===Contraception===
In certain cultures, such as in the [[Oneida Community]],<ref name="Francoeur" /> retrograde ejaculation is performed as a form of primitive [[male birth control]] (''coitus saxonicus'').<ref name="Francoeur">{{Cite book|title = A Descriptive Dictionary and Atlas of Sexology|last = Francoeur|first = Robert T.|publisher = Greenwood Press|year = 1991|isbn = 0313259437|location = Westport, Connecticut|pages = 114, 547}}</ref> However, the practice is not considered a reliable method compared to most modern types of birth control. Besides the  lack of protection from [[Sexually transmitted infection|STDs]], the technique itself can be hard to execute correctly during the act of coitus, especially if the male does not fully understand the anatomy involved. Many doctors also do not recommend ''coitus saxonicus'' due to the risk of putting pressure on the [[pudendal nerve]], which can cause numbness in the [[penis]].{{Citation needed|date=May 2012}}

===Taoism===
{{Main|Huanjing bunao}}
[[Taoists]] and some fields of [[alternative medicine]] recommend and teach deliberate retrograde ejaculation as a way of "conserving the body's energy". It was believed that retrograde ejaculation caused the sperm to travel into the head and nourish the brain, or that energy is conserved physically by keeping the sperm (and thereby, the "intelligence" that created it) in the body.<ref>{{cite book |author=Wile, Douglas |title=Art of the bedchamber: the Chinese sexual yoga classics including women's solo meditation texts |publisher=State University of New York Press |location=Albany, N.Y |year=1992 |isbn=0-7914-0886-8 }}</ref> However, there are other Taoist perspectives on the general subject of ejaculation and techniques that do not involve retrograde ejaculation (see [[Taoist sexual practices]]).
