Mycosis vaginalis is caused by Candida albicans. The most typical symptom is vulvar itching, and when it is severe, the itching can make the patient restless and sleepless, especially at night when the itching is aggravated. Painful urination and painful intercourse can occur, which can have a serious impact on life. If mycosis is not treated in time, it can lead to cervicitis, and retrograde infection can lead to endometritis, tubitis, pelvic inflammatory disease, etc. Since mycobacterial infection produces a large amount of secretions that will prevent sperm from entering the uterine cavity, and Candida albicans will engulf sperm, it will easily cause infertility. Even if pregnant, the development of the fetus will also bring adverse effects, prone to miscarriage. In late pregnancy, if the pathogen infects the fetal membranes, premature rupture of the membranes can occur. Therefore, if mycosis vaginalis occurs, it is important to treat it in time to avoid serious consequences.
