Determining the gender of a baby by observing stretch marks is a popular belief, but there is a lack of scientific evidence. Factors such as the shape, location, and color of stretch marks may be related to gender, but they cannot be used as the only basis for determining gender. Therefore, when predicting the gender of the fetus, we should maintain a rational and scientific attitude and not rely too much on this method. At the same time, we should also pay attention to the health and happiness of pregnant women and provide her with the best care and support.
