Physical barriers are one type of contraception method that work by physically blocking sperm from reaching the egg. These methods include:
1. Condoms: Male condoms are sheaths made of latex or polyurethane that are worn over the penis during sexual intercourse. They prevent pregnancy by collecting semen and preventing it from entering the vagina. Female condoms are also available, which are inserted into the vagina before intercourse.
2. Diaphragms: A diaphragm is a shallow, dome-shaped cup made of silicone that is inserted into the vagina to cover the cervix. It acts as a barrier to prevent sperm from entering the uterus.
3. Cervical caps: Similar to diaphragms, cervical caps are small, thimble-shaped devices made of silicone that are placed over the cervix to block sperm from entering the uterus.
4. Spermicides: Spermicides are chemical substances that come in various forms, such as creams, gels, foams, or suppositories. They contain chemicals that immobilize or kill sperm, preventing them from reaching the egg.
These physical barrier methods are readily available, relatively inexpensive, and do not require a prescription. However, they must be used correctly and consistently to be effective in preventing pregnancy. Additionally, they do not protect against sexually transmitted infections (STIs), so it is recommended to use them in combination with other methods, such as condoms, for dual protection.
