What is an ectopic pregnancy?

Out of place pregnan. Ectopic literally means out of place in greek. It is the term used to describe reproductive accidents where the fertilized egg implants outside the endometrial cavity that is prepared to support it. The most common site is the fallopian tube (>90%), followed by more rare and catastrophic locations, including the ovary, cervix, abdominal cavity. Any of those types can prove life-threatening!
Very rarely. Instead of implanting in the uterus the embryo has implanted in the fallopian tubes.
