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.
There are two Fallopian tubes attached to either side of the end of the uterus. Each tube will end near one ovary. This place is called the fimbria. The Fallopian tubes are not attached to the ovaries, but open into the peritoneal cavity. In humans, the Fallopian tubes are about 7 - 14 cm long.
