title: Neural tube defects in association with copper intrauterine devices.
abstract: Copper-bearing intrauterine devices are being increasingly used for contraception. A growing number of pregnancies, which may subsequently carry to term, are therefore being exposed to high levels of copper at the critical period of organogenesis, with risk of possible teratogenesis. Two cases of anencephaly occurring in association with these devices are reported.
