Implanon®Â : difficultés d'insertion et de retrait, échecs contraceptifs

Discussion and conclusion. - Occurrence of pregnancy is possible with Implanon®, due to errors in the insertion technique (device not really inserted) or to a non-respect of the SPC recommendations (drug-drug interaction or untimely insertion). Insertion problems can lead to localisation problems (implant not visible by X-ray) then needing further tests and even harmful practice (removal under general anaesthesia). That is why a real and strict training is highly recommended to physicians.
