Tubal factors Blocked or damaged fallopian tubes prevent sperm from getting to your egg and also prevent the fertilized egg from getting to your uterus. Leading causes of tube problems include pelvic inflammatory disease, sexually transmitted infections (such as chlamydia), and previous sterilization surgery. Possible symptoms: None. Possible solutions: Surgery to open the tubes. If surgery fails, or if the tubes are too damaged to repair, they may be removed before having IVF in order to improve your chances of pregnancy. Success rates: Conception rates after surgery vary widely, depending on the location and severity of the tube blockage and the amount of postoperative scar tissue that develops.
