Our cervix has certain glands that secrete cervical mucus. This mucus helps to keep the vagina moist and lubricated. It also plays a role in fertility and conception as this mucus becomes wet, stretchy and slippery at the time of ovulation so that intercourse at this time becomes easy and helps to result in a pregnancy.
Nabothian cysts, also known as cervical cysts, form when these mucus-producing glands in the cervix become blocked, causing a buildup of mucus and the formation of a small fluid-filled sac. Nabothian cysts are quite common and often don't cause any symptoms or require treatment. They are generally benign and not a cause for significant concern.
They can be diagnosed by a physical, internal examination as also on an ultrasound. Once you have visited your healthcare provider and have confirmed that the cysts are indeed Nabothian cysts, and aren’t infected, you need not worry about them.
