The role of fallopian tube is to pick up the egg released form the ovary, allow the sperm to travel through it, provide site for fertilization. Once the egg is fertilized, the resulting embryo must travel from the fallopian tubes to the uterus in order for pregnancy to occur. Damaged or blocked fallopian tubes can prevent a woman from getting pregnant by interfering with the movement of the sperm to the egg or the fertilized egg to the uterus. About 20-30% women with infertility have tubal problems.
Tubal blockages or damage may be caused by pelvic inflammatory disease, endometriosis, previous surgeries, ectopic pregnancy or tubal ligation. Most women with damaged or blocked fallopian tubes do not experience any symptoms.
