Abstract
A chemical contraception system is described in which the spermicidal chemical, for example, "Nonoxynol-9", is provided in a powder or tablet form and is dissolved in a solvent, primarily water, immediately before use. The solution containing the spermacide is then allowed to soak into an applicator matrix, such as a sponge or pad. The spermicide-impregnated matrix is inserted into the vagina and later removed. The system can be provided in kit form (FIGS. 1 and 2) including a storage container for the powder, a mixing container, and a measuring spoon, or in a pre-packaged form where the chemical has already been added to the sponge. Among the preferred embodiments of the system are the use of the spermicidal chemical in powder or tablet form and the use of a sponge for vaginal retention of the spermicidal solution.
