Outcomes of pregnancy with an IUDin situ — a population based case — control study

Abstract

Use of IUDs was examined among 962 women whose pregnancy was terminated at the University Hospital of Trondheim, Norway during 1983. Ectopic pregnancy was significantly more often diagnosed among women with an IUD in place at conception compared to non-users (7.8%vs 1.3%,pin situ had spontaneous abortion more often than non-users (15.6%vs 7.0%,pppvs 1,3%pvs 7,0%p<0,05). Estos hallazgos requiren mas investigación. El escaso numero de embarazos ectópicos a continuación de la falla contraceptiva de un DIU en relación con la cantidad de embarazos en el mismo tiempo, podría explicar la falta de una relación demonstrable entre el aumento de uso de los DIU y el aumento de tasas de embarazos ectópicos.
