Bartholin’s glands are pea sized glands situated on either side of the vagina. They secret fluid through ducts to help to provide lubrication to the vagina. A Bartholin’s cyst, also called a Bartholin glands cyst is when the duct of these glands becomes blocked, and fluid backs up causing a cyst. Sometimes this can cause pain and irritation or become infected, requiring medical attention, or they can resolve themselves over time.
