The procedure can be performed in your doctor's office without general anesthesia .
During the first 3 months following the procedure, your body and the micro-inserts work together to form a tissue barrier that prevents sperm from reaching the egg. During this period, you will need to use another form of birth control.
After 3 months, your doctor will perform an Essure Confirmation Test, a special type of x-ray to confirm that your tubes are completely blocked and you can rely on the Essure micro-inserts for birth control.
Unlike birth control pills, patches, rings, and some forms of IUDs, Essure does not contain hormones to interfere with your natural menstrual cycle. Your periods should more or less continue in their natural state.
