The fallopian tube is a crucial structure involved in successful reproduction and, like with all structures in the human body, sometimes problems occur that hinder the structure's ability to function properly.
A female has two Fallopian tubes. These tubes connect each ovary to the uterus. Each tube is 1 1/2 to 2 inches long in an adult female and about as wide as a piece of spaghetti. One end of the Fallopian tube has a fringed funnel that wraps around much of the ovary and scoops up a released egg or ovum.
