Rectal Douching Associated with Receptive Anal Intercourse: A Literature Review.

ABSTRACT

To inform the development of HIV-prevention rectal douches, we reviewed the scientific literature and online instructional videos on rectal douching associated with receptive anal intercourse (RAI). Up to 88% of men who practice RAI ever have douched, while 43-64% have douched recently. Of them, 87-97% douche before RAI and 13-48% afterwards. Water, occasionally mixed with soap or salt, is used most often, although up to 31% of men use commercial products. Douching is more common among individuals reporting substance use, sexually transmitted infections, or being HIV-infected. Scant literature is available on women's rectal douching practices, but it is apparently less frequent than among men (32 vs. 70%). Videos advise using 2-3 doses of liquid and retaining it for 10-30 s before expelling. These findings can inform the development of a safe and acceptable rectal douche for HIV prevention.
