ABSTRACT OF THE DISCLOSURE A method and apparatus for contraception wherein an applicator houses a fluid-expansible, hydrophilic, tam- pon material in its unactivated, compressed state separate from a reservoir of spermicide or medicament. The appli- cator preferably includes a manually frangible portion of the spermicide reservoir or a fluid communication passage to bring the spermicide into contact with the fluid-expan- sible tampon material upon command prior to use. After activating by moistening, the spermicide-impregnated, ex- panded tampon can be readily inserted into a vagina by use of the applicator. Preferably, the tampon is made from a body of purposefully-compressed, memory-retentive, hydro- philic material having a resilience and a high coefficient of expansion when moistened to act as a barrier to the os uteri, to fill the vaginal fornices and absorb ejaculate. Various shapes of the tampon are disclosed, as are methods of making and using the invention.
