The Amenorrhea With Etonogestrel Implant

October 13, 2023 updated by: Mohammed Khairy Ali, Assiut University

The Rate and Predictors of Amenorrhea at 1-year Follow-up in Women Using Etonogestrel Implant

The etonogestrel subdermal implant has been available worldwide for more than 15 years. The action of etonogestrel subdermal implant is principal via suppression of ovulation, but it also has effects on cervical mucus and in some women induces suppression of endometrial proliferation. Several studies have confirmed its high efficacy and convenience. The uterine bleeding problems and in particular irregular bleeding and amenorrhea are major side effects of etonogestrel subdermal implant. A considerable number of patients request early removal due to bleeding changes. Amenorrhea occurs in about 22% in etonogestrel subdermal implant users. Despite the presence of many studies that reported the prevalence of etonogestrel subdermal implant-associated bleeding, little is known about the predictive factors affecting menstrual bleeding patterns especially amenorrhea after etonogestrel subdermal implant insertion. These predictive factors should be provided prior to the etonogestrel subdermal implant insertion which may improve acceptance and continuation of etonogestrel subdermal implant.
