Barrier methods of birth control are designed to create a physical barrier between the sperm and egg cells such that fertilization is prevented from occurring. Some of the most common types of barrier contraception for both men and women include the diaphragm, condoms, contraceptive sponge and cervical cap. Spermicides are a form of chemical contraceptive designed to kill sperm and are normally used in combination with barrier contraception methods to increase their effectiveness. This is because the spermicide will kill most of the sperm that enters the vagina, while the barrier contraception thereafter blocks any surviving sperm from passing through the cervix and fertilizing an egg.
Barrier methods of birth control generally do not result in the development of side effects as hormonal contraceptives are known to do. In addition, it is possible to purchase certain types of barrier birth control such as condoms and sponges without requiring a prescription. The only disadvantage to using barrier birth control is the development of an allergic reaction to the latex in condoms. What’s more, with the exception of male and female condoms designed to protect against sexually transmitted disease infections, most other forms of barrier birth control cannot effectively protect you from contracting STDs. It is therefore advisable to always use a condom whenever you have sexual intercourse so as to protect yourself from STDs such as HIV/AIDS. Natural membrane condoms made out of sheepskin are not recommended however, as these do not offer perfect protection against all STDs.
