Mycosis vaginalis does not usually lead to irregular periods, because when a woman has mycosis vaginalis, there is only a lot of mold growth in the vagina, but it does not affect normal ovulation, nor does it affect the shedding of the endometrium, nor does it affect the endocrine function of the ovarian hypothalamus pituitary. Therefore, when a woman has mycotic vaginitis, it does not cause irregular menstruation, but it does cause abnormal leucorrhea, which usually results in beanbag-like leucorrhea, as well as itching, burning and stinging in the vulva. This itching and painful manifestations may be significantly worse during intercourse or when urinating.
