What Are the Causes of Ectopic Pregnancy?
Ectopic pregnancy occurs in about 1 in 100 pregnancies. The fertilized egg normally spends 4-5 days travelling down the fallopian tube to the womb where it implants. The most common reason for an ectopic pregnancy is damage to the fallopian tube resulting in a blockage or narrowing which may delay the passage of the fertilized egg allowing it to implant in the tube.
