Postcoital contraception, also known as emergency contraception, is a method of birth control that can be used after unprotected sexual intercourse to prevent pregnancy. It is typically used in cases where a contraceptive method was not used or failed, such as a condom breaking or slipping off, a missed or late contraceptive pill, or sexual assault.
There are two types of emergency contraception available: hormonal emergency contraception and copper intrauterine devices (IUDs).
Hormonal emergency contraception, also known as the "morning-after pill," contains a high dose of synthetic progestin or a combination of progestin and estrogen. It works by preventing or delaying ovulation, and may also make it more difficult for sperm to fertilize an egg or for a fertilized egg to implant in the uterus. Hormonal emergency contraception can be taken within 72-120 hours (depending on the type of pill) after unprotected sex, but is most effective if taken as soon as possible.
Copper IUDs are also an effective form of emergency contraception and can be inserted up to five days after unprotected sex. They work by preventing fertilization and inhibiting implantation of a fertilized egg. Copper IUDs can also be used as long-term contraception, and have the added benefit of being highly effective and not requiring repeated doses.
Emergency contraception does not protect against sexually transmitted infections (STIs), and should not be used as a primary form of contraception. It is important to discuss your options for regular contraception with a healthcare provider to find the most effective and appropriate method for your needs.
