Simultaneous use of a levonorgestrel intrauterine system and an etonogestrel subdermal implant for debilitating adolescent endometriosis.

Adolescent familial endometriosis may cause severe and persistent symptoms that are disruptive to lifestyle. Treatment may be difficult in many cases. We describe the novel and successful first use of a simultaneous combination of a levonorgestrel intrauterine system and an etonogestrel subdermal implant in a teenager with severe pain symptoms as a result of laparoscopically confirmed endometriosis, which was refractory to other treatments.
