Fallopian tube obstruction occurs when the tubes become blocked, clogged or in the presence of fibrotic processes that cause them not to function as they should. They are a major problem of infertility. Some studies establish that in 20-24% of the cases of female infertility there is some type of tubal alteration.
Tubal unblocking surgery is extremely complex, requires a long time to assess its effectiveness, and we cannot guarantee that it will be 100% effective. This type of procedure can again lead to the formation of adhesions, tubal fibrosis and may be one of the reasons for the formation of an ectopic pregnancy (outside the uterine cavity).
For all these reasons, IVF is the treatment of choice in cases of bilateral tubal obstruction.
