The continuation rate at the end of this five-year clinical study was 60% with no accidental pregnancy occurring throughout the five years. The post-removal conception rate in women desiring pregnancy was 92% at the end of two years. The majority of acceptors described the overall experience with the implants as favourable. In fact, 75% of the women planning to use contraception after removal of the implants were going to use implants again.
