A three-year clinical evaluation of Norplant-2 rods in Singapore.

A three-year clinical evaluation of Norplant-2 rods in Singapore shows that no pregnancy occurred during the three years of use. The continuation rate at the end of three years was 74%. Desire for planned pregnancy was the main reason for removal during the three years. The post-removal conception rate in women desiring planned pregnancy was 50.0% at the end of one year. This low rate could be attributed to the four women deciding against a pregnancy after removal. However, despite this apparent reason one needs to monitor the post-removal return of fertility closely in the years to come.
