Washing inside the vagina is linked with vaginal infections in the research literature, and that literature shows no sign that it prevents them. The studies behind this come from several settings, but they mostly describe habits and associations.
Most of this work, however, is observational. Other differences between women who douche and women who do not cannot be ruled out, so the evidence describes an association rather than proof that washing inside the vagina is itself the cause.
What does the evidence say about washing inside the vagina?
The evidence links washing inside the vagina with vaginal infections and does not show that it protects against them. A systematic review and meta-analysis of prospective longitudinal studies found that no specific intravaginal practice reduced the risk of vaginal infection or HIV acquisition.

That review pooled 22 publications from 15 prospective longitudinal studies in sub-Saharan Africa and the USA. HIV incidence was higher among women reporting intravaginal cleansing, with a wide interval and high heterogeneity (adjusted hazard ratio 1.88; 95 percent confidence interval 0.53 to 6.69; heterogeneity 83.2 percent), so the estimate is statistically inconclusive. Bacterial vaginosis was associated with HIV acquisition (adjusted hazard ratio 1.57; 1.26 to 1.94). The authors called the pathway plausible, said conclusive evidence is lacking, and noted that some practices might be harmful.
A cross-sectional study of 314 women aged 18 to 49 with abnormal vaginal discharge in central Uganda, conducted between May and August 2025, found non-albicans Candida infection in 23.6 percent (74 of 314; confidence interval 19.0 to 28.8). Vaginal douching was associated with that infection (adjusted odds ratio 2.25; confidence interval 1.15 to 4.41), as were number of sexual partners and recent antibiotic use. The authors stressed that other causes of discharge were not excluded, so interpretation must be cautious.
[More research needed: most of these studies are cross-sectional or observational and cannot show that vaginal douching itself causes infection.] The adjusted odds ratio of 2.25 for non-albicans Candida infection among women with abnormal discharge who douched remains an association within one sample of 314 women.
What do women actually do, and how well informed are they?
Surveys show that washing practices differ between countries and between groups within one country. These studies measure how common a habit is, not how risky it is.
A cross-sectional study in Beirut, Lebanon, surveyed 249 women, 136 nurses and 113 patients. A history of vulvovaginitis was reported by 21.3 percent of nurses and 38.9 percent of patients. Douching was reported by 14 percent of nurses and 17 percent of patients, wet wipes by 7 percent and 43.4 percent, and feminine deodorant sprays by 1.5 percent and 4.4 percent. Most women washed the area at least 2 times a day. The authors reported a lack of awareness, especially among patients; the design cannot show cause and effect.
An online survey of about 10,000 women aged 18 to 60 in 10 countries found that daily intimate care ranged from 38 to 91 percent depending on the country, and most women were comfortable talking about female genitalia while still considering it a taboo topic, particularly younger generations. The sample is an online panel, so the range of 38 to 91 percent in daily intimate care describes reported habit rather than measured risk.
Where does daily external washing fit?
Gentle daily cleansing of the external genital area, the vulva, is described in a 2017 review as an important aspect of intimate hygiene according to international guidelines. That guidance concerns the vulva, the outside of the genital area.
Its authors note that medical papers on the vulva are scarce, which limits what any review of this topic can establish. Three of the four authors work in research and development at a company that makes feminine hygiene products. A review written under those conditions is not independent evidence.
The editorial position of Behckam.com is that the available evidence links vaginal douching with vaginal infections, and there is no evidence that it prevents infection. Daily external washing of the vulva is described as guidance-based in that single review, which is not enough on its own to settle the question.
If I have itching, odour or unusual discharge, what is a sensible step?
A medical assessment is the sensible step, rather than self-treatment or more intensive washing, because itching, odour and unusual discharge have several different causes that call for different responses. Washing more often does not address a cause that did not begin with hygiene.
In the consulting room, worry about genital cleanliness usually comes with shame; my first question is where that worry came from. It may trace to a specific remark, a previous infection or inherited advice rather than to a character flaw.
Concern about cleanliness is not a failing; distinguishing the causes of odour or discharge is a clinical task.
No. The systematic review and meta-analysis found no specific intravaginal practice that protected against vaginal infection or HIV, so prevention is not supported.
Why can’t we say it causes infection?
The studies are cross-sectional or observational. Women who douche may differ in sexual behaviour, antibiotic use or previous infection, and other causes of discharge were not excluded, so other explanations cannot be ruled out.
Do these results apply to all women?
No. The study populations were in sub-Saharan Africa and the USA, Lebanon and Uganda, and the designs were cross-sectional or survey-based, so the findings should not be generalised beyond them.
How well have wet wipes and deodorant sprays been studied in these studies?
Barely. The Lebanese survey reported only how often women used them, not what happened afterwards, so frequency of use describes habit rather than risk.
Conclusion: What does the evidence say about washing the genital area?
The adjusted odds ratio of 2.25 for non-albicans Candida infection among women with abnormal discharge who douched is one association from one cross-sectional sample of 314 women, and it sits within a literature that finds no protective effect from washing inside the vagina. Daily gentle washing of the vulva is described as part of hygiene in international guidance, and better-designed studies could settle the questions that remain open.
