Copper intrauterine device (IUD) users were found to have a lower risk of high-grade cervical neoplasms compared with levonorgestrel-releasing intrauterine system (LNG-IUS) users, according to a study published in Obstetrics & Gynecology.1
However, the relative risk of cervical neoplasms of LNG-IUS users compared with the general population remains unknown.
“Copper and hormonal IUDs may have different physiological effects on the female genitourinary system,” lead author Matthew Spotnitz, MD, MPH, a postdoctoral research scientist within the Department of Biomedical Informatics at Columbia, said in a press release.2 “Consequently, the risk of cervical neoplasms may be different for copper and hormonal IUD users. Our findings may help patients and healthcare providers make informed decisions about whether the benefits of hormonal IUD use, compared to copper IUD use, are…
