Technically, the term embryo refers to the products of conception after implantation into the wall of the womb, usually nearly two weeks after fertilization, up until the eighth week. Embryos contain stem cells which, according to scientists, could be used to cure a wide range of conditions. Stem cells can be coaxed into growing cells of any other type, which makes them potentially very useful indeed. However, removing stem cells from an embryo will kill the embryo, which some people object to. From the mid 1970s, IVF was being developed and research was carried out on the spare embryos produced. This research helped to improve IVF techniques, as well as to better understand the earliest stages of human development. Research also shed light on a variety of inheritable disorders. In Turkish Law, assisted reproduction treatment (ART) services are regulated with the Regulation of Assisted Reproductive Treatment Centers Act (RAPTCA) The Regulation was issued in 1987, but it has been amended several times since. Also, article 90 of the Turkish Penal Code covers some aspects of research on embryos. At the same time, the Biomedicine Convention (Oviedo Convention), signed by Turkey and which entered into force in 2003, has binding regulations about this issue. Different legal regulations and some ethical guidelines are in conflict with each other, creating much confusion for the researchers. In this paper these conflicts are discussed, giving some practical proposals.
