[Acceptability of norplant implantation in China].

The results of Norplant subdermal implants in 10,718 women receiving Norplant-6 and 1,208 women accepted Norplant-2 were analyzed. Up to May 31, 1988, the 3-year cumulative pregnancy rate was 0.2 per 100 acceptor for Norplant-6 and 0.1 per 100 acceptor for Norplant-2 and the continuation rate was 78.6 and 73.1 per 100 acceptor respectively. Menstrual disturbance constituted the majority (70%) of terminations. Cumulative termination rate for medical reasons was only 4.2 and 6.3 per 100 acceptor for Norplant-6 and Norplant-2 respectively. It is concluded preliminarily that the Norplant subdermal implantable contraceptive system is a safe and acceptable to the Chinese women.
