[edit] History
The earliest recorded barrier methods are those of stem pessaries, found in Egypt. The diaphragm and reusable condoms became common after the invention of rubber vulcanization in the early nineteenth century. Condoms became even more popular after the 1930s invention of latex, which enabled the creation of thinner, disposable prophylactics.
[edit] Methods
The following are barrier methods of contraception.
- Condom
- Cervical cap
- Diaphragm (contraception)
- Female condom
- Lea's Shield
- SILCS diaphragm (still in clinical testing)
The contraceptive sponge is usually considered a barrier method, but not always, as its effectiveness relies largely on spermicide.
The male condom provides excellent protection against sexually transmitted infections. Using a condom is sometimes referred to as "practicing safer sex".

- Dental dams have no contraceptive use, but offer STD protection during oral sex (see unprotected sex).
