What is FemBloc?

The FemBloc Permanent Contraceptive System is being studied as a permanent birth control method that does not involve surgery or incisions, and is performed right in the doctor's office. The FemBloc approach consists of two steps:

Step 1 – Treatment Procedure: A thin plastic tube is placed into your uterus, and a small amount of liquid (1/4 teaspoon) is delivered towards your fallopian tubes. The thin tube is then removed, leaving only the liquid behind. The liquid triggers a natural healing process that causes the fallopian tubes to close over time, which is how FemBloc is designed to prevent pregnancy.

Step 2 – Confirmation Procedures: About 3 months later, your doctor will perform an ultrasound in the office and then you will receive a radiology test to confirm that your fallopian tubes are closed. After the results of both tests, you may be told to use FemBloc as your birth control.

The FemBloc Permanent Contraceptive System is now being offered at select women’s health centers through a new research study. If you qualify and choose to join the study, you will receive the FemBloc System and all-study related care at no cost. You do not need insurance to participate.
