The causes of vaginitis are mainly caused by bacterial infection, trichomonas infection, pseudohyphae infection, etc. It is usually not very relevant to circumcision. 1. Bacterial infection: It is mainly due to the fact that the flora of the vagina is dominated by Lactobacillus, and if there is an abnormality in the vaginal flora, it leads to the growth of other bacteria and microorganisms, which in turn leads to bacterial vaginosis. 2. Trichomonas infection: It is mainly caused by Trichomonas vaginalis infection, which may be caused by sexual intercourse, public bath, bath towel and other contacts. 3. Pseudomonas aeruginosa: many women can have Pseudomonas aeruginosa parasites in their vagina, and if women’s resistance decreases, there may be a large number of Pseudomonas aeruginosa reproduction, which can lead to vaginitis. So in general, vaginitis is not directly related to circumcision, but if vaginitis occurs, you should seek medical treatment in time.
