| description | Methods for the synthesis and use of several variations of styrene maleic acid-based polymers and the hydrogel tissue bridges that can be formed from such polymers. Specifically, a method is disclosed for synthesizing a styrene maleic acid-based polymer that can be dissolved in DMSO and injected into the vasa deferentia of male subjects, creating a hydrogel tissue bridge. This hydrogel tissue bridge can occlude the vas deferens, thus forming an effective male contraceptive. Additionally, this male contraceptive can be reversed by injecting the lumen of the vas deferens with a basic buffer solution to dissolve and remove the hydrogel tissue bridge. |
