Barrier contraception methods attempt to prevent pregnancy by forming an impenetrable barrier between sexual partners.
Protection against disease[edit]
Some barrier methods provide good protection against sexually transmitted disease (STD). Using one of these devices is referred to as practicing safer sex.
- Condom, male or female
- Dental dams do not have any contraceptive uses, but offer STD protection during oral sex.
Some evidence indicates that cells in the cervix are particularly susceptible to infection. Devices that cover the cervix may provide some protection from STDs; however, this protection is much less than that provided by devices that cover more of the male or female genitalia.
History[edit]
The earliest recorded barrier methods are pessaries (vaginal suppositories) in Egypt.
Use of 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, disposible prophylactics.
