Spermicides
Highlights
TSpermicides come in many different forms, including foam, film, cream, gel, and suppositories. They are inserted into the vagina. They block the cervix (the opening to the uterus) and also make it harder for sperm to reach an egg. Spermicides are more effective when used with other methods of birth control like condoms or diaphragms.2
