The fetal pole is an early sign of embryonic development, typically visible on an ultrasound scan around 6-7 weeks into a pregnancy. It appears as a small, curved structure with a heartbeat and is important in determining the viability and health of the developing fetus.
The fetal pole forms from the embryonic disk, which is the inner layer of cells in the developing embryo. As the fetal pole develops, it begins to take on a recognizable shape and begins to develop important structures such as the brain, heart, and digestive system.
The presence of a fetal pole on an ultrasound is a reassuring sign that the pregnancy is progressing normally. However, the absence of a fetal pole can be an indication of a miscarriage or an ectopic pregnancy, and additional tests or monitoring may be necessary.
It’s important to note that the fetal pole is just one aspect of fetal development and that continued monitoring throughout pregnancy is necessary to ensure a healthy outcome.
