The fallopian tubes are reproductive organs that connect the ovaries to the uterus. They are critical in ovulation. After ovulation, the egg travels from the ovary, down the fallopian tube, to the uterus. Fertilization of the egg also occurs in the fallopian tube. When an egg is fertilized, it moves through the tube to the uterus, where it implants on the uterine wall. Damage or blockage of the fallopian tube can prevent fertilization from happening, and/or it can prevent the fertilized egg from reaching the uterus.
Causes of Blocked Fallopian Tubes
There are several reasons why a fallopian tube may become blocked, such as prior infection, ectopic pregnancy, fibroids, or endometriosis.
