Tubal disorders (block / abnormal function) can block an egg from entering or traveling down the fallopian tube to meet the sperm, preventing fertilization. Pelvic infections and sexually transmitted infections damage the tube.
Tubal disorders can be diagnosed using various tests like Hysterosalpingography (HSG), Saline sonography, Laparoscopy with chromotubation (dye test).
