Ectopic pregnancy results from a delay in the passage of the fertilized ovum through Fallopian tube. This delay can result from anatomical abnormalities of the tubes, such as constriction and false passage formation (e.g. diverticulum), or from tubal dysfunction as altered contractility or abnormal ciliary activity.

Ethylenediaminetetraacetic acid, widely abbreviated as EDTA (for other names, see Table), is an aminopolycarboxylic acid and a colourless, water-soluble solid.t is widely used to dissolve limescale. Its usefulness arises because of its role as a hexadentate (six-toothed) ligand and chelating agent, i.e., its ability to sequester metal ions such as Ca 2+ and Fe 3+ . After being bound by EDTA, metal ions remain in solution but exhibit diminished reactivity.
