âThe Machineâ International Trailer. The Machine is being hailed as one of 2014's best sci-fi thrillers. Coming to U.K. theaters this March, the story, from director Caradog W. James, takes place in an impoverished world plunged deep into a Cold War with a new enemy.
The blockage is caused by an adherent plug of mucus that forms over the opening of the fallopian tube(s). In some women, injecting the contrast for the HSG will dislodge the plug with immediate opacification of both of the tubes. Therefore, for some women they only need the HSG to open their tubes.
The main function of the fallopian tubes is to facilitate the transportation of the sperm to the egg and afterward to actively facilitate the passage of a fertilized egg into the uterus. The fallopian tube achieves this through a peristaltic and ciliary movement. 2 The fallopian tubes also secrete mucus, thereby aiding the transportation of both sperm and egg. The fertilization of the egg usually happens in the ampulla part of the fallopian tube.
