Many women mistakenly believe that frequent douching can reduce the likelihood of gynecological diseases, and many women have even developed the habit of washing the vulva with soap or cleansers every day or after sexual intercourse. Frequent vaginal douching can disrupt the balance of the vaginal environment and may even lead to the development of gynecological diseases such as salpingitis, pelvic inflammatory disease, infertility, and even ectopic pregnancy.
