Both mycosis vaginalis and trichomoniasis are common gynecological vaginal inflammatory conditions because they both cause changes in the vaginal environment, resulting in vaginal inflammation, so both vaginal infections can cause odor, but neither is a relatively bad smell. If they have to be compared, trichomoniasis may produce a greater odor, and mycosis is a little more uncomfortable because the itchiness is more severe in mycosis. Other vaginitis can also produce odors, such as bacterial vaginosis, which can be more severe, and if mycosis vaginalis or trichomoniasis is combined with a bacterial infection, it can produce a more severe odor. There are also tumors in the vagina, cervix or other parts of the body, such as vulvar tumors, and the odor is more severe when ulceration occurs.
