Tubal Blockage

Tubal blockage, or tubal occlusion, is a permanent birth control method that results in a blockage in the fallopian tubes thus preventing sperm from reaching the egg. The procedure takes about 35 minutes for a trained physician to perform. No general anaesthetic or incision through the abdomen is required. Micro-inserts are placed in the fallopian tubes via the vagina and cervix. Over the next several weeks, a natural barrier forms around the micro-inserts which prevents sperm from reaching the eggs so conception never occurs. The ovaries will continue to release eggs, but they will naturally be absorbed back into the body. Three months after the procedure, an x-ray test will be performed to confirm that the tubes are fully blocked and that the women can rely on tubal blockage for permanent birth control. Until that time, the woman must continue using another form of birth control (other than IUD or IUS). 

The procedure is only available through trained doctors, generally OB/GYNs, in a hospital setting. Not all hospitals offer the procedure. Some hospitals have a cap on the number of tubal blockages they will perform in a year.

Advantages

• Tubal blockage is 99.8% effective.
• It is a permanent procedure. The procedure cannot be reversed if you change your mind afterwards.
• Additional birth control must be used for 3 months after the procedure.

Risks

• Perforation, expulsion, or other unsatisfactory location of the micro-insert
• Pregnancy and increased risk of ectopic pregnancy
• Pain, cramping, vaginal bleeding, menstrual pattern changes, light periods at first then longer, heavier periods lasting up to 6–8 weeks
• Nausea/vomiting, or fainting
• Allergic reaction to the materials (The micro-inserts are made from polyester fibers, nickel-titanium and stainless steel)
• Tubal blockage does not protect against sexually transmitted infections
