Condoms are designed to prevent pregnancy and sexually transmitted infections (STIs). Several key components and features might be present, depending on the specific type of condom.
Condom Components & Coatings:
- Latex: Most condoms are made from latex, a natural rubber, offering high protection.
- Polyisoprene: A synthetic alternative for those with latex allergies.
- Polyurethane: Another synthetic option providing protection against STIs and pregnancy.
- Spermicide: Some condoms are coated with spermicide, a chemical that helps kill or immobilize sperm. Nonoxynol-9 is a common spermicide. [Reference: Some condoms are coated with spermicide, a substance that slows down sperm so it can't reach your partner's egg.]
- Lubricant: Many condoms come pre-lubricated to enhance comfort and reduce friction. Water-based lubricants are recommended for latex condoms, avoiding oil-based options. [Reference: Non-lubricated condoms — as the name suggests — aren't lubricated. You can use an over-the-counter lubricant with any condom. With latex condoms, use water-based lubricants — not oil-based lube. ]
- Flavors and Colors: Some condoms are flavored or colored for enhanced experience, though this doesn't affect their primary function. [Reference: Are your flavored condoms and lubricants safe to be used for oral sex? ]
Effectiveness:
Condom effectiveness varies depending on correct and consistent use. When used perfectly, condoms can be highly effective in preventing both pregnancy and STIs. However, typical use effectiveness is lower due to potential errors in usage. [References: condoms are about 87% effective..., If used correctly every time you have sex, condoms are extremely effective at preventing STIs and pregnancy., Condoms are up to 98% effective at preventing pregnancy if you use them correctly every time you have sex. If not used correctly they're 82% effective. ]
Important Considerations:
- Proper Usage: Correct use is crucial for maximum effectiveness. [Reference: If used correctly every time you have sex, condoms are extremely effective at preventing STIs and pregnancy. ]
- Single Use: Condoms are designed for single use only and should never be reused. [Reference: If you have sex again (oral, anal, or vaginal) use a new condom. Condoms should never be reused.]
- Expiration Dates: Check expiration dates before use.
