By DEFINITION a human fetus cannot be a parasite on a human mother. The parasite must be a different kind of creature than the host. Also a host cannot create its own parasite, as that would be fruitless and serve no purpose. The offspring of any mammel cannot possibly be defined as a parasite, as shown above in the given definitions. The parasite must be different than the host. A human fetus is human, contains human DNA, and is not a separate being that invaded a host to maintain life or further its own life. The human female's body functions to create the fetus. The fetus does not invade, it is made by the body of the human female.
