Bioresponsive Polymers Effective in Contraception, Hormone Delivery, and Protection against STDs

Women across the globe face a serious health threat from preventable STD and HIV infections due to the lack of compliance from partners in condom use. Development of a safe and effective method for prevention has a broad market. Currently available methodologies, such as the female condom, sponge etc., are only marginally effective. This technology would provide a better and more effective alternative for women. This is a biopolymer that would be applied to the vagina or anus precoitus and upon exposure to seminal fluid is able to release an encapsulated drug. The biopolymer is valuable for administering microbicides to counteract HIV or other STDs as well as possible uses in hormone therapy or contraception.

Benefits
HIV is a serious threat to millions of people worldwide. Currently the best way, to prevent transmission of these diseases is condom use. This invention provides an alternative method that does not require partner compliance. The product has application in the prevention of other STDs as well as a contraceptive or hormone delivery system.
