What is an Ectopic Pregnancy?
Fertilization normally occurs in the fallopian tube and then the smooth muscle contractions and the ciliary beat within the fallopian tubes assisting the fertilized egg in its journey into the uterus. (Cilia are microscopic hairs-like projections at the end of the fallopian tubes that beat rhythmically at a frequency of 3.46Hz as they sway!) In an ectopic pregnancy, the fertilized egg fails to implant in a normal position in the uterus where it can develop and thrive. Instead, the pregnancy attaches elsewhere in the reproductive system or body – usually in the fallopian tube. But an ectopic pregnancy can also implant near the ovaries, in a prior c-section scar inside the uterus, in the lower part of the cervix, or in the abdominal cavity, etc. About 90% of all ectopic pregnancies occur in the fallopian tube.
