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.
Fallopian tube obstruction is a major cause of female infertility. Blocked fallopian tubes are unable to let the ovum and the sperm converge, thus making fertilization impossible. Fallopian Tubes are also known as oviducts, uterine tubes, and salpinges (singular salpinx).
