| abstract |
A method for sterilizing a female or male patient is provided. The method comprises introducing into a reproductive duct of the patient a composition comprising a nucleophilic component, such as a thiol, and a component containing a conjugated unsaturated bond, such as an acrylate. The composition crosslinks within the reproductive duct. Within a female patient, the composition is introduced into one or both uterine tubes. The composition gels in the uterine tubes, thereby blocking the uterine tubes and preventing conception. |
