Spermicides
What they do: Kill sperm upon contact. Spermicides have been used since 1850 BC.
What it is: A foam sponge, loaded with different spermicides, that absorbs and traps sperm. It also acts as a barrier.
Pros: You don't need to be fitted for the sponge and it can be inserted up to six hours before intercourse.
Cons: Must stay in the vagina for about eight hours after intercourse to continue killing sperm. Can be tricky to remove. Can't be used during your period. Tastes bad, so may interfere with oral sex.
Side-effects: None
Effectiveness: 75-90%. Much more effective if used with a condom.
- Vaginal Contraceptive Film
What it is: A thin film placed in the vagina before sex, which dissolves quickly while it releases spermicide.
