HOW IT WORKS:

Two types are available in the US: a progesterone impregnated IUD (Progestasert®)  and a copper T-shaped IUD (ParaGuard®). The IUD may prevent pregnancy by interfering with: sperm movement (the ability of the sperm to fertilize the egg) or implantation (nesting of a fertilized egg into the lining of the uterus).  (Now the most widely used method of reversible birth control in the world.)  A third type LNgIUD contains a hormone called levonorgestrel.

EFFECTIVENESS:

Copper-T IUD - 99% Progesterone IUD - 97%

AVERAGE COST:

Copper-T $250-750/10 years Progesterone IUD $250-400/year

ADVANTAGES:

Requires no attention except for monthly checks for the string. Fertility returns immediately upon removal. Does not interfere with lovemaking. Copper IUD needs to be changed only every 10 years; progesterone IUD needs changed yearly. Can be used while breast-feeding.

DISADVANTAGES:

Does not protect against STD's.  Should not be used by women who have: never had children or still want children; an allergy to copper for the ParaGuard® IUD; an artificial heart valve; a history of decreased immune problems; multiple sex partners; a history of pelvic inflammatory disease (PID) or tubal pregnancy. Side effects possible: cramps, backache, spotting, heavy periods. May have an increase risk for tubal pregnancy, PID, infertility.  Must check for string after every period - May be expelled without knowing it.

HOW TO USE IT:

Must be inserted by a health care professional, usually at the time of a period. You must check for the string after every period.

YOU NEED TO CALL A HEALTH CARE PROVIDER IMMEDIATELY IF:

You experience any of the following: the string can no longer be felt; the end of the IUD can be felt at the cervix; a missed or a late period; a very light period; severe cramping and/or abdominal pain; pain or bleeding with intercourse; fever or chills of no known reason; more than one sexual partner; or foul smelling vaginal discharge.
