There are many causes of mycotic vaginitis: 1. Some women use antibiotics for a long time, more than seven days, which can cause dysbiosis and lead to mycotic vaginitis. 2. Some women wash their underwear and dry it in the shade or in a humid environment, and then wear it again, which can cause mycotic spores to grow and cause mycotic vaginitis to occur. 3. The fact that some women have cross-infection during intercourse is related to the fact that some men’s genitals are not hygienic and can contain a lot of mold spores, which can cause mold and spores to multiply during intercourse and cause mycotic vaginitis. When there is mycotic vaginal inflammation, it must be actively treated, which can cause urinary tract infections and can also cause pain in the small abdomen.
