The MAP is a birth control pill taken within 72 hours of an episode of unprotected intercourse to reduce the chance of pregnancy. Examples of unprotected intercourse include: no birth control method used, broken condom, other method failure or misuse, or sexual assault. What is the MAP? The MAP is a particular birth control pill prescribed at a different dosage than what women normally use for ongoing contraception. How does the MAP work? The MAP may prevent pregnancy in one or more of the following ways: * by preventing ovulation. * by thickening cervical mucus. * by temporarily altering the uterine lining. * by reducing the chance of fertilization in the fallopian tube. The MAP is not RU486 (often referred to as the "French Abortion Pill"). ************** We don't yet have definitive answers on how IUDs work. They may prevent pregnancy by affecting sperm, eggs and the lining of the uterus. Recent studies indicate that IUDs may also have effects outside of the uterus. In one study, IUD users demonstrated no evidence of fertilisation. The IUD appears to operate in one of two ways: by interfering with migration of sperm from the vagina to the fallopian tube by accelerating egg transport through the fallopian tube, thus impeding fertilisation The IUD is an effective contraceptive for monogamous women with no history of sexually transmitted diseases or pelvic inflammatory disease.
