  • Expanding access to a new, more affordable levonorgestrel intrauterine system in Kenya: Service delivery costs compared with other contraceptive methods and perspectives of key opinion leaders

    The levonorgestrel intrauterine system (LNG-IUS) is one of the most effective forms of contraception. In this study, the authors calculated the direct service delivery costs per couple-years of protection of various family planning methods and interviewed key opinion leaders. The costs of a new LNG-IUS compares favorably with other contraceptive methods common in Kenya. These results indicate that introducing a new, more affordable LNG-IUS product could help expand choice for women in Kenya and increase use of long-acting reversible contraception.

    In a randomized controlled trial in which 414 Jamaican women at high risk for sexually transmitted infections received an implant immediately or at the end of a three-month study period, results showed that condom use was not higher in women receiving the implant immediately. These results support promotion of implants in high-risk populations and can help refine counseling for condom use among implant users.

  • In vivo release of levonorgestrel from Sino-implant (II) — an innovative comparison of explant data

    This innovative approach measured the amount of contraceptive hormone remaining in removed Sino-implant (II) rods that had been used for various lengths of time and compared the data to reports from Jadelle. The results provide evidence that Sino-implant (II) may perform similarly to Jadelle over three years and remain a highly effective contraceptive beyond this time point.
