Si aceptamos como "embarazo prolongado" toda gestación que va más allá de la duración normal , es necesario precisar qué se en tiende por "duración normal ". En todas las especies animales la duración del ciclo gravídico tiende a ser constante; en la especie humana dura aproximadamente 280 días, a partir del primer día de la última menstruación. Este lapso corresponde a la "duración aparente", pues la "duración real" es el tiempo transcurrido desde la fecundación hasta el parto.
