Authors report two different cases of broken Implanon® of women attended at our Family Planning Clinic. DISCUSSION: In situ implants may spontaneously and asymptomatically break, although some uncertainty relies on whether that situation has a real impact on the contraceptive effectiveness or on bleeding patterns. Even more, it can be argued if, as a result of an occurrence of that nature, the implant shall or shall not be removed before the envisaged 3-year period of effectiveness. CONCLUSION: Currently, the clinical significance of implant breakage remains unknown. The decision to remove a broken or bent implant should be based on clinical judgements considering patients' wishes.engContraceptive Agents, Female/administration & dosageContraceptive Agents, Female/adverse effectsDesogestrel/administration & dosageDesogestrel/adverse effectsDevice RemovalDrug ImplantsEquipment FailureFamily Planning ServicesPortugalMAC GINjournal article
