RecruitingDevice studyClinical Protocol CERN Feasibility StudyThe goal of this clinical trial is to learn if the intravaginal Cern device works to treat bacterial vaginosis and fungal vaginitis in premenopausal women. It will also learn about the safety of the device. The main questions it aims to answer are: Does the device accomplish symptom resolution and negative diagnostic tests post-treatment? What medical problems do participants have when using the intravaginal device? Participants will use the investigational intravaginal device for 5 consecutive days, participate in teleconferences and weekly follow-ups, attend in-clinic visits, and maintain a study diary.
