Funded Activity Summary

The purpose of this research project is to develop a novel form of contraception that could meet the dual objectives of fertility regulation and prevention of sexually transmitted disease (STD). A particularly novel feature of this proposed spermicide-microbicide is that it has to be activated by spermatozoa i.e the formulation comprises a pro-spermicide that only generates the active principle on contact with sperm. This aspect of the method sets it apart from all other forms of topical contraception because unlike barrier methods and vaginal creams or foams, its use will not be coitus related. Ultimately it is envisaged that the product could be incorporated into a soft pliable vaginal sponge and left in situ until such time as it becomes activated following intercourse. Such a method should be particularly acceptable to young women who are vulnerable to both STDs and unwanted pregnancy as indicated by (a) the relatively high rates of STDs in adolescent girls, particularly in the indigenous community, and (b) the fact that 50% of all recorded pregnancies to Australian women under 19 years of age end in abortion. The method exploits the susceptibility of human spermatozoa and pathogenic organisms responsible for STDs to oxidative stress and, in effect, mimics a naturally occurring cause of male infertility. If successful, this project would produce a female centred method of contraception and STD prevention that would revolutionize reproductive health care for young women worldwide, as well as generating intellectual property of considerable potential value to the nation.
