Monif (OBSTET GYNECOL 1999;94:630–1) notes that observational studies cannot demonstrate a causal relationship between vaginal douching and adverse health effects. However, the data supporting such a relationship are more extensive than presented. In 1997 Zhang et al1 drew the following conclusions from a meta-analysis of 13 studies: “Frequent douching appears to be highly associated with pelvic inflammatory disease and modestly associated with ectopic pregnancy and cervical cancer.” Other health problems that have been associated with douching are bacterial vaginosis,2 chla-mydial infection,3,4 and low birth weight.5

A clinical trial has been initiated to study douching and clinically detected pelvic inflammatory disease (PID). However, other health outcomes also need to be investigated, especially because silent PID can cause infertility and ectopic pregnancy. Experimental work is needed to understand more fully the effects of douching on vaginal ecology. An estimated 27% of women in the United States douche regularly,6 so answering the question “To douche or not to douche?” deserves high priority. In the meantime, women need to be informed that douching is not required for normal vaginal hygiene and may involve health risks.
