A hydrosalpinx is a fallopian tube that is blocked at its distal end on the opposite side from the entrance to the uterine cavity. It is filled with inflammatory fluid and is most likely the end result of a pelvic infection. This inflammatory fluid can flow into the uterus and provide a hostile environment that will prevent implantation of an embryo. A hydrosalpinx does not have healthy cilia (microscopic hairs that normally push the egg or embryo towards the uterus), so transferred embryos that are pushed into the fallopian tubes after a uterine contraction can become trapped and may implant there, resulting in a dangerous ectopic pregnancy that requires surgical or medical removal.Symptoms
Some patients experience pain in the lower abdominal pain or pelvic pain that may or may not be recurring. Others are asymptomatic. For many, infertility is the first and only symptom.
