title: IUD compared with oral contraception in nulliparae.
abstract: 172 nulliparae attending a Swedish family planning clinic were studied. Doctors and midwives with various experiences gave the contraceptive method. Continuation rate at 12 months was 58 per cent for IUD and 86 per cent for OC. The expulsion rate in the IUD group was 11 per cent and in 30 per cent of IUD users the device was removed because of adverse effects. 10 per cent of the IUD group and 5 per cent of the OC group discontinued their method without introducing another one, thereby risking an unwanted pregnancy.
