The importance of the tubes
To study the permeability of the fallopian tubes, hysterosalpingography is performed. This test is carried out in the Department of Radiology: it consists of injecting through the neck of the uterus a contrast medium that fills the uterine cavity, the tubes and leaves inside the abdomen. This x-ray requires special preparation of the patient to avoid it being painful.
If it is normal, we will think that the tubes are permeable, although it does not assure us that they perfectly fulfill all their functions of nutrition and transport of gametes and embryos.
If it is pathological, it can definitively diagnose a tubal factor, for example if there is obstruction to the passage of contrast or hydrosalpinx (pathological dilatation of the tubes).
In some cases this test is doubtful and it is advisable to perform a diagnostic paroscopy to be able to make a better assessment of tubal function.
The tubes can be affected by pelvic infections (currently the most frequent agents are Chlamydias), by endometriosis, or it can be secondary to gynecological surgery.
If it is confirmed that there is an affection of the tubes, the necessary treatment is In Vitro Fertilization.
