Problems with the fallopian tubes and abnormalities in the pelvis

[Ernesto]

The fallopian tube may be blocked or damaged, preventing the sperm from reaching the egg or preventing the egg or fertilized egg (zygote) from moving from the ovary to the uterus to be implanted. Abnormalities in the pelvis can prevent the egg from attaching to (implanting in) the lining of the uterus and can block the fallopian tubes.

To identify the problem, doctors may use x-rays taken after a radiopaque contrast agent is injected through the cervix, do ultrasonography after a salt solution is injected inside the uterus (sonohysterography), or view the organs through a viewing tube (laparoscope) inserted through an incision just below the navel.
The fallopian tubes can sometimes be repaired, but in vitro fertilization is usually recommended.
