Implants: The Next Generation
Family planning programs around the world are introducing the new one- or two-rod implant systems Implanon®, Jadelle®, and in some countries Sino-Implant (II)®. By 2008 Norplant®, the six-capsule implant system, first introduced in mid-1980s, will no longer be available. Like Norplant, the new implants are highly effective, and like Norplant, they alter bleeding patterns. Their most important improvement over Norplant is easier and quicker insertion and removal. Sino-Implant (II) may also cost much less than other implants. The new implants are recommended for as much as three to five years of use, depending on the make. Thus they are particularly suitable for women who want to space births. Indeed, for many women implants are a convenient method. Once inserted into a woman's arm, the implants do not require any action by the user. Since implants do not contain estrogen, they do not decrease production of breast milk and thus are suitable for breastfeeding women. They are also a good choice for women who do not want more children but are not ready to opt for sterilization, which is permanent. With new implants making the method easier to provide, more programs may want to begin offering implants. Programs currently offering Norplant will need to consider how to make the transition to the newer implants and to meet possibly greater demand.
