Current concepts on the use of IUDs.
IUDs have been used in Singapore since the mid 1960's but acceptance of this contraceptive method has fluctuated widely as a result of misconceptions regarding possible complications. The current generation of copper bearing devices have pregnancy rates below 1 per 100 women per year and this rate falls further with continued use. New developments which hold promise include a device releasing 20 mcg levonorgestrel per day and a copper device without a plastic frame which may reduce menstrual blood loss and dysmenorrhoea. In addition to the well established contra-indications to use, a past history of pelvic inflammatory disease or ectopic pregnancy, promiscuity, nulliparity and age less than 25 are now considered relative contraindications.
