Chen MJ, et al. - Researchers, in this study, examined a novel concept of initiating the etonogestrel implant as a “back-up” method in women who desire using combined oral contraceptives (COC) but want to decrease their risk of unintended pregnancy with a more effective method. They observed that women using COCs were willing to initiate the implant as a “back-up” method to improve pregnancy prevention in this proof-of-concept study. Most women continued the implant through 6 months and after completing study participation.
