Implants are one of the most effective and longest-lasting methods.

• Far less than 1 pregnancy would be expected per 100 women using implants over the first year. Specifically, just 1 pregnancy would be expected per 1,000 women using implants over the first year, which means that 999 of every 1,000 women using implants will not become pregnant. Less than 1 pregnancy would be expected per 100 women over the duration of use of the implant.
• A small risk of pregnancy remains beyond the first year of use and continues as long as the woman is using implants.
• For heavier women, the effectiveness of Jadelle and Levoplant may decrease near the end of the duration of use stated on the label. These users may want to replace their implants sooner (see Question 9).
