Three dimensional ultrasound allows us to see the product of conception, which in this period is called embryo, at as little as two months of pregnancy, when the embryo measures only 15mm.

Three dimensional ultrasound allows us to see the product of conception, which in this period is called embryo, at as little as two months of pregnancy, when the embryo measures only 15mm! Note how, in this animated sequence, it is possible to see the embryo inside the gestational sac. The head is clearly visible, as are the trunk and the stumps that will become the four limbs. The small sphere nearby is the yolk sac: Its purpose is to nourish the embryo in this initial stage. The embryo is connected to the yolk sac through the small umbilical cord, which is barely visible. The embryo is completely surrounded by the uterus.
In this period the product of conception is called fetus. Its initial growth is remarkable, the small stumps that were visible two weeks before have now developed into well formed legs and arms; the face, the eyes, nose, mouth and ears are already well defined. Notice the position of the head, slightly bent to one side, and the upper and lower limbs. We can even get a 360° view!
Here we are in the fifth month, and we see the fetus making coordinated automatic movements, which give it a ‘human’ air. In these images the hand and the thumb, the arm, neck and trunk are clearly visible. Notice how the face is still thin in this period – the baby will have puffier cheeks after the 7th month.
