NorplantR contraceptive subdermal implants: Two-year experience in Singapore

Norplant contraceptive implants are Silastic containing levonorgestrel implants. This study describes our two-year experience with 100 acceptors of Norplant implants in Singapore. No pregnancies occurred during the first two years of use. Desire for planned pregnancy and disruption of menstrual rhythm were the two main reasons for twenty implant removals during the two years. The continuation rate at the end of two years was 79%. The post-removal conception rate in women desiring pregnancy was 90% at the end of one year. It thus appears that the Norplant contraceptive system offers a highly effective, acceptable, reversible and safe method of contraception.
