El porcentaje de muertes fetales inexplicadas oscila entre un 21% a 50%; se define como la muerte que ocurre en fetos con edad gestacional mayor de 20 semanas o peso superior a 500 g, en la cual ni la autopsia ni el examen histológico del cordón umbilical, placenta y membranas, se logra identificar la causa. Los factores asociados con muerte fetal inexplicada son edad materna mayor de 35 años, sobrepeso, nivel educativo menor de 10 años, cigarrillo y bajo nivel socioeconómico, entre otros. La muerte fetal se relaciona con enfermedades maternas, trombofilia, accidentes del cordón, alteraciones citogenéticas, metabólicas e infecciones congénitas, principalmente.
