Before Sex
Before sex
Barrier methods of contraception include diaphragms, condoms and cervical caps. They work by preventing sperm from reaching an egg by creating a physical barrier between the two.
The condom is the only contraception that offers protection against infections.
External condoms (male condoms)
An external condom fits over an erect penis and is made of very thin latex (rubber). For those with a latex allergy, polyurethane (plastic) or polyisoprene is available.
Effectiveness: External condoms are most effective when used perfectly. They’re 98% effective at preventing pregnancy with perfect use and 82% effective with typical use.
Remember before sex: Use a new condom each time you have sex.
STI protection: Yes. External condoms and internal condoms are the only methods of contraception that help protect you from STIs.
Internal condoms (female condoms)
An internal condom is made of polyurethane (soft plastic) or nitrile polymer (synthetic rubber). It’s put in the vagina and loosely lines it.
Effectiveness: Internal condoms are most effective when used perfectly. They’re 95% effective at preventing pregnancy with perfect use and 79% effective with typical use.
Remember before sex: Use a new condom each time you have sex. You can insert in advance if you want to.
STI protection: Yes. External condoms and internal condoms are the only methods of contraception that help protect you from STIs.
Diaphragms & cervical caps
They fit inside your vagina and cover your cervix (entrance to the uterus – womb). Diaphragms and caps come in different shapes and sizes.
Vaginal diaphragms are circular domes made of silicone with a flexible rim.
Cervical caps are smaller and are made of silicone.
To be effective, diaphragms and caps should be used with a spermicide. Spermicide is a substance that kills sperm. It’s available in different forms, such as cream or gel.
Effectiveness: Diaphragms and caps are most effective when used perfectly, and used with spermicide. They’re 92-96% effective at preventing pregnancy with perfect use and around 71-88% effective with typical use.
Remember before sex: You need to put in the diaphragm or cap before you have sex.
STI protection: No. Use external condoms or internal condoms to help protect yourself from STIs
