Reversibility of clip sterilization

A spring clip designed to be applied to the fallopian tube for sterilization without electrocoagulation was applied to 10 pigs. After documenting the prevention of pregnancy for 3 months, the clips were removed and successful reanastomosis was performed on eight pigs. Six of these pigs became pregnant within 2 months of the reanastomosis. This paper describes the technique of the reanastomosis and documents the potential reversibility of spring clip sterilization.
