Metal ring - a safe,effective, economical and convenient approach of fertility regulation

A survey of 25,000 women from 1450 villages in China has indicated that the metal ring is a safe, effective, and convenient method of contraception. The continuation rate was 79.3% after 1 year of use and 55.2% after 5 years of use. Factors that were most influential in continuation included insertion after menstruation, insertion during breastfeeding, age at 1st birth, insertion after abortion, level of the health care system, age at insertion, intensity of labor, number of births before insertion, and number of abortions before insertion. The expulsion rate ranged from 11.4-20.7%. The accidental pregnancy rate was 2.4-6.8%. Events such as expulsion and unintended pregnancy showed an association with parity, number of abortions, level of the health care system, and insertion during the breastfeeding period. No serious complications were noted in any of the women fitted wih metal rings.
