The contraceptive sponge contains nonoxynol-9 which is the spermicide used in many vaginal foams, suppositories, and jellies. It is made from a soft, round polyurethane sponge with a cloth ribbon attached to one side and an indentation on the other.
It stops conception in two ways:
- Due to its absorptive qualities the sponge acts as a barrier trapping sperm keeping them inside and hindering their passage through the cervix
- The sponge releases a spermicide continuously over a 24-hour period immobilizing or killing the sperm
It should be used with a condom to protect against the transfusion of STD’s.
*The sponge has not been available in the US since 1994
