Abstract

This work sought to carry out a comparative analysis of in vitro fertilization (IVF) vis-à-vis St. Thomas Aquinas’ Natural Law Theory. Both of them emanated from problem of infertility. IVF makes use of artificial insemination for fertilization which is quite contrary to the natural process of sexual reproduction. This work makes use of analytic method to analyse comparatively in vitro fertilization and St. Thomas Aquinas’ Natural Law Theory. Thus, this work conceives that IVF is one of the assisted reproductive technologies in the scientific exploration of genetic engineering and bio-technology which emanated to tackle the problem of genetic inheritance outside marriage. It contravenes the coital or natural reproduction which conforms to St. Thomas Aquinas’ second precept of natural law. Again, IVF is artificial as such it is pruned to many complications. There is no adequate information given by the medical practitioners or providers of this service on the health hazards or risks involve in IVF. In addition, in vitro fertilization makes provision for donor gamete and surrogate motherhood which may have many negative implications both for the couples, off-spring, gestation mother, and society at large.
