Pelvic infections, endometriosis and hydrosalpinx are causes of tubal factor, that is to say, problems in the fallopian tubes leading to difficulties in achieving pregnancy.
However, there are other causes that can alter the patency and movement of the fallopian tubes:
- Previous pelvic surgeries, due to the formation of adhesions.
- Ectopic pregnancy, if it requires a salpingectomy, that is, the removal of the fallopian tube.
- Tubal ligation.
In addition, although it is not very frequent, it is also possible that a woman can suffer from a congenital malformation of the fallopian tubes.
