Were you looking for information about a Douche? Doosh is a common misspelling of douche.
A douche is a method of rinsing or cleaning out the vagina by squirting water or other solutions into it. Approximately 37 percent of American women between the ages of 15 and 44 douche regularly. However, healthcare providers don't recommend douching to clean the vagina, since it can make a woman more prone to bacterial infections or problems with getting pregnant. It is best to let the vagina clean itself rather than using a douche, since the chemical balance of the vagina is highly sensitive.
