B locked Fallopian Tubes are defined are the reproductive organs of our body. These are two thin tubes, one on each sides of the uterus which helps to the mature egg from the ovaries to uterus. A fallopian tube is the prime most organs in the fertilisation process. Fertilisation of the eggs takes place when eggs are travelling from the fallopian tubes to the uterus. So when the fallopian tubes are blocked, the traversal of egg through fallopian tubes to the uterus cannot occur resulting into the hindrance into the fertilisation process. Single tube blockages as well as blockage of the tubes are dangerous for the fertilisation process. Blocked fallopian tubes become one of the top most reasons of infertility nowadays.
