The connection between belly shape and fetal gender is a long-standing misconception. Scientific research shows that the gender of the fetus is determined by the X or Y chromosome carried by the sperm, not the shape of the mother\’s abdomen. The bulge and shape of the abdomen are affected by many factors, including the size and position of the fetus and the mother\’s body shape. Therefore, we should not use belly shape as a reliable basis for determining the gender of the fetus.
