IUDs produce no adverse systemic effects. Ectopic pregnancies are reduced overall; however, the ratio of extrauterine to intrauterine pregnancy is increased if conception does occur. Menstrual blood loss and dysmenorrhea are decreased with the LNG-IUS. Twenty percent of women experience amenorrhea with the LNG-IUS.  The risk of pelvic inflammatory disease decreases in patients using IUDs (after the peri-insertion window) as compared to patients using no contraceptive method.  Risks of endometrial and ovarian cancer decrease for patient using IUDs.  Complications of the intrauterine device are rare and differ little between adolescents and adults, making these devices safe to use in adolescents.
