Chronic vulvovaginitis is the most wide-spread gynecological pathology among women of childbearing age. The chief causations of nonspecific vulvovaginitis are reduction in oestrogen, disturbances in vaginal acidity, intestine dysbacteriosis, local and general immune disturbances. The growth of vagina opportunistic pathogenic flora is closely connected with the increase of bacterial slimes on vagina mucus. Sulphur balneotherapy in the form of general baths and vaginal irrigations, mechanical physiotherapy promotes disruption of bacterial slimes, oestrogen elevation, immune reconstruction and vaginal biocenosis, which has positive effect on patients’ fertility level, frequency of obstetrical and perinatal pathologies.
