Birth Control - Barrier Methods

Male Condoms (Latex, Polyurethane, Animal Skin)
Male condoms are most often made of latex. However, people who are allergic to latex use condoms made of polyurethane. Male condoms can be used as a method of prevention for both pregnancy and sexually transmitted infections. Male condoms are about 98% effective at preventing pregnancy when used correctly. Male condoms may be used for oral sex on a male, or can be cut to create a dental dam for used on a female for oral sex. Male condoms may only be used once, and usually cost around a dollar.
For information on how to properly use a condom:
Female Condoms
Female condoms are made of polyurethane. Female condoms are larger than male condoms and have two rings instead of one. Female condoms are 95% effective at preventing pregnancy when used correctly and are more effective at preventing sexually transmitted infections than male condoms. A female condom is used by inserting the ring in the closed end into the vagina, the same way a tampon is inserted, with the open end outside the vagina. Female condoms may only be used once, but can be used along with spermicides and also may be inserted hours before sexual intercourse occurs. Female condoms may also be used for anal sex.
Female condoms cost around $3.60 per condom.
Dental Dam
Dental dam is NOT a method of preventing pregnancy. Dental dam is used to prevent sexually transmitted infections and is for use when performing oral sex on a female.
Diaphragm
A diaphragm is a flexible latex cup that is inserted into the vagina. The diaphragm works to prevent pregnancy by covering the cervix so sperm may not enter the uterus. The diaphragm is most effective when it is used in combination with a spermicide. When used correctly, a diaphragm is about 94% effective at preventing pregnancy. Diaphragms do not prevent sexually transmitted infections. A cervical cap is similar to a diaphragm, and is made out of silicone, so can be used by people who are allergic to latex.
