Vaginal douching: evidence for risks or benefits to women's health.

Vaginal douching is the process of intravaginal cleansing with a liquid solution. Douching is used for personal hygiene or aesthetic reasons, for preventing or treating an infection (1), to cleanse after menstruation or sex, and to prevent pregnancy (2). For at least 100 years, there have been conflicting views on the benefits or harm in douching. Although there is a broad consensus that douching should be avoided during pregnancy, there is less agreement regarding douching for hygiene and relief of vaginitis symptoms. Two earlier reviews of douching data in women (3) and adolescents (4) have concluded that douching is harmful and should be discouraged because of its association with pelvic inflammatory disease, ectopic pregnancy, and perhaps other conditions. Nonetheless, douching continues to be a common practice. We seek to review the evidence of the impact of douching on women’s health.
