Answer:

True

Explanation:

In vitro fertilization refers to the laboratory techniques by which a woman's egg is fertilized by injecting a man's sperm in order to develop an embryo outside the body. Subsequently, this embryo can be then implanted into the female uterus to continue with its development. Nowadays, it is possible to decide the stage of development in which the fetus (developed from an embryo) is transferred to the uterus. This situation raises ethical, moral and legal concerns about when a fetus can be regarded as a human being.
