1. A method for user-controllable release of a therapeutically effective amount of chemical agent into the vaginal canal of a user, for use by those in need of administration of said chemical agent, comprising:
- (a) placing a vaginal sponge within said vaginal canal, said vaginal sponge comprising a truncated sphere, said sphere being from 11/4 to 3 inches in diameter and comprising from 50-250 spherical substructures per lineal inch, each of said spherical substructures comprising groups of cells, said sponge having a density of at least 2 pounds (lbs) per cubic foot and a tensile strength of at least 20 pounds per square inch, said sponge having a liquid added thereto, said liquid comprising blocked liquid and freely releasable liquid, said blocked liquid comprising liquid which will remain in said sponge upon the imposition of a mechanical pressure upon said sponge, said freely releasable liquid comprising liquid which will be released from said sponge upon the imposition of mechanical pressure upon said sponge, said freely releasable liquid having said therapeutically effective amount of chemical agent dissolved therein; and
,(b) voluntarily compressing said sponge by deliberately imposing mechanical pressure upon said sponge by internal bodily movements of the female reproductive tract of said user to compress said sponge and at least partially release said freely releasable liquid from said sponge and deliver said therapeutically effective amount of chemical agent into the vaginal canal of the user.

Abstract
A product for the administration of an active pharmaceutical agent via the vaginal canal comprising:
(a) a sealed, air-tight package, enclosing therein;
(b) a sponge impregnated with a liquid containing an effective amount of an active pharmaceutical agent, said liquid being present in an amount greater than that which is blocked within said sponge but less than the saturation value of said sponge such that when said sponge is inserted in the vaginal canal it will release liquid therefrom.

4. A device for user-controlled release of a therapeutically effective amount of chemical agent into the vaginal canal of a user, for those in need of administration of said chemical agent, comprising:
a sponge having the shape of a truncated sphere for placement in the vaginal fornix, said sponge comprising approximately spherical substructures, each of said spherical substructures comprising groups of cells, said sponge having approximately 50 to 250 of said spherical substructures per lineal inch, said sphere being from 11/4 to 3 inches in diameter, said sponge having a density of at least 2 pounds per cubic foot and a tensile strength of at least 20 pounds per square inch, said sponge having a liquid added thereto, said liquid comprising blocked liquid and freely releasable liquid, said blocked liquid comprising liquid which will remain in said sponge upon the imposition of a mechanical pressure upon said sponge, said freely releasable liquid comprising liquid which will be released from said sponge into the vaginal canal of a user upon the imposition of mechanical pressure upon said sponge by internal bodily movements of a user when said sponge is seated in the user'"'"'s vaginal fornix, said freely releasable liquid having said therapeutically effective amount of chemical agent dissolved therein. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
