Although we often think of medical technological devices as scientific tools to track progress and improve well-being, a few also satisfy our burning curiosity. A couple, for example, may simply want to know whether an expected child will be a boy or a girl and what their child will look like.
While this will have no bearing on the health of the mother or child, it may have some practical value, such as deciding whether to paint the nursery blue or pink. In short, the primary benefit of learning about the gender and appearance of a child is to satisfy curiosity.
Interestingly enough if you’re expecting a baby and asking yourself “What will my baby look like?” science can now do more than ever to teach you about your child such as informing you what your child’s physical characteristics may look like in the future.
