Reproductive technology is an example in which Mother Church teaches her faithful the truth, based on the teaching of Jesus Christ. To understand why certain reproductive technology is morally licit or illicit, one must first comprehend the sacrament of marriage and the dignity of each human being. This new life is the fruit of the love between a married couple, in the conjugal act, exhibiting unity and procreation. In vitro fertilization or IVF, is a reproductive technique with the intention to procreate. The ova from the woman, along with the sperm from the man, are retrieved and the two are placed in a lab dish.
Fertilization soon follows and the embryo is placed in the woman's uterus.
The intention to procreate is a good end, but the means to that end is contrary to moral, natural law. It puts the child at the hands of technology, and completely disrespects the sanctity of human life. In IVF, conception not only takes place outside the mother's body, but also outside the conjugal act itself. The man and woman no longer come together as one, in body and spirit, in the unitive way. The mixing of sperm and ova result in the creation of embryos, or human beings.
