title: Norplant-2 rods: one year experience in Singapore.
abstract: Norplant-2 contraceptive implants consist of two silastic rods in which levonorgestrel has been incorporated with the polymer. This study describes our experience with 100 acceptors of the Norplant-2 rods in Singapore. No pregnancies occurred during the first year of use. Menstrual irregularities was the main complaint associated with the use of Norplant-2. However, the incidence of menstrual irregularities appeared to diminish with time and the continuation rate at the end of one year was 95.0 per cent. Thus, it appears that the Norplant-2 rod systems offer a highly effective, convenient means of contraception which should be well accepted in future.
