Bartholin's glands are two small glands located on either side of the vaginal opening in females. They are responsible for producing a fluid that helps lubricate the vagina during sexual arousal. This lubrication is important for comfortable intercourse and overall vaginal health. These glands can sometimes become blocked or infected, leading to a condition known as a Bartholin's cyst. If the cyst becomes large or painful, it may require medical treatment. Regular gynecological check-ups can help monitor the health of these glands and address any potential issues early on.
