Women who receive a contraceptive known as an intrauterine device or IUD immediately following a first trimester abortion experience few complications and are less likely to have an unintended pregnancy than those who delay getting an IUD by several weeks, according to a new study at Oregon Health & Science University. The findings are published in the June 9 New England Journal of Medicine. Research has shown that IUDs are safe, highly effective, long-term reversible contraceptives that don’t require active use once they’ve been inserted. IUDs are underused, however, in part because federal policy prohibits physicians from providing contraceptive services at the time of an abortion, the investigators report.
