Specializes in Obstetrics and Gynecology
Ectopic causes: Even thought the HSG shows patency and they are "open" there can be impediments to the fertilized egg traversing and implanting in the uterus such as narrowing of the isthmus of the tube. Most ectopic pregnancies are caused by fallopian tube infections. There is a 10 % chance of a 2nd ectopic after the first.
