Since introducing Norplant over 20 years ago in Kenya, demand for contraceptive implants has remained high and implant costs are dropping substantially.
An assessment of the Kenyan experience with implants was conducted to understand level of demand, capacity to provide services and reproductive health impact of possible increased use. Interviews were conducted with 35 key Kenyan informants. By modeling increases in national implant use (at the expense of oral contraceptives), reductions in the annual number of unintended pregnancies were estimated.
Kenya has an unmet need for implants and the current network of trained providers appears ready to increase the volume of services. If 100,000 users of oral contraceptives switch to implants, then an estimated 26,000 unintended pregnancies can be averted over a 5-year period.
With increased purchases of implants by international donor agencies, Kenya can reduce reliance on short-term hormonal methods and reduce the 45% prevalence rate of unintended pregnancy.
自20多年前在肯尼亚引入诺普兰皮下埋植避孕剂以来，对避孕植入物的需求一直居高不下，且植入物成本大幅下降。
对肯尼亚使用植入物的情况进行了评估，以了解需求水平、提供服务的能力以及可能增加使用量对生殖健康的影响。对35名肯尼亚关键信息提供者进行了访谈。通过模拟全国植入物使用量的增加（以口服避孕药为代价），估计了意外怀孕年数的减少情况。
肯尼亚对植入物有未满足的需求，目前经过培训的服务提供者网络似乎已准备好增加服务量。如果10万名口服避孕药使用者改用植入物，那么在5年期间估计可避免2.6万例意外怀孕。
随着国际捐助机构增加对植入物的采购，肯尼亚可以减少对短期激素方法的依赖，并降低45%的意外怀孕发生率。
