The medical term for a blocked fallopian tube is a tubal occlusion. Tubal abnormalities occur when injury to the fallopian tube, usually from infection, causes the end of the fallopian to close, either partly or fully. The fallopian tubes are muscular tubes that are lined delicate hair-like structures. These “hairs” work in both directions; helping an egg to travel from the ovaries down to the womb (uterus) and helping sperm travel up from the womb. If one or both fallopian tubes are blocked or have any abnormalities then sperm might not be able to travel up in the fallopian tube(s) to reach the egg in order to fertilise it. ICI will not work if sperm cannot swim through the fallopian tubes. If you suspect you could have tubal occlusion or abnormalities, speak to your GP before trying to conceive. You can also email the Béa Care Team if you have any questions or concerns.
