Barrier methods of birth control block sperm from entering the uterus. Using a spermicide with a barrier method gives you the best possible barrier method protection.
The spermicide kills most of the sperm that enter the vagina.
The barrier method then blocks any remaining sperm from passing through the cervix to fertilize an egg.
Barrier methods include the diaphragm, cervical cap, male condom, and female condom and spermicidal foam, sponges, and film. Unlike other methods of birth control, barrier methods are used only when you have sexual intercourse.
Please let me know if you need any clarification. I'm always happy to answer your questions.
