The reverse happens during the progesterone dominant luteal phase of the cycle, where the functional obstruction is resolved. However, failure of this physiological change will result in a complete anatomical obstruction of the FT. Such persistent obstruction may eventually calcify, ultimately resulting in fibrosis and permanent occlusion of the tube.

Persistent intraluminal obstruction can occur as a consequence of local inflammation in the FT and can exist anywhere along its length. Obstruction at the fimbrial end causes a phimosis like picture and clubbing of the edges of the FT \[[@B88-jcm-09-01905]\], which can lead to fluid stagnation in the lumen, forming a hydrosalpinx or less commonly a haematosalpinx. In the latter, menstrual blood
