Introduction: The use of medically assisted reproduction is an important solution with regards to the reduction in fertility in the world and millions of people who face infertility. The infertility is a problem which occurs all over the world. However, it is not equally spread. The development of medically assisted reproduction procedures has brought many expectations and solutions to couples who face infertility and many additional laws and ethical discussions at the same time. Medically assisted reproduction represents a new medical field which demands constant development. Purpose: The purpose of the master’s thesis is to study whether Slovenian regulation in the field of medically assisted reproduction is in accordance with the regulations of the other EU members. Methods: The methods of work used in the master’s thesis are the descriptive method and the comparative legal method of work in the field of social sciences. The emphasis was on the methodology from the field of legal sciences. We reviewed and analyzed the domestic and foreign literature regarding the medically assisted reproduction, legal regulations, and ethical dilemmas in the field. Statutory provisions from the field of medical treatment with the medically assisted reproduction procedures in the EU member states were the primary source. We did not study other laws from the field of medical legislation in order to compare the legal regulation of the medical treatment with the medically assisted reproduction procedures according to the indicators of legislation. Results: In some member states of the EU, the field of medical treatment with the medically assisted reproduction procedures is regulated with the directives, instructions, general laws on medical activity or differently. We reviewed all 28 member states of the EU and as many as 27 member states have regulated this field of medical treatment by a statute. When comparing the selected indicators of the Slovenian legal regulation of medically assisted reproduction with the selected indicators of the legal regulation of the medically assisted reproduction in other EU member states, we were not able to identify major deviations. Thus, the main hypothesis of the research can be confirmed. Discussion and conclusion: In the EU member states, the medical treatment of infertility by the medically assisted reproduction is regulated by law in most of the countries. However, the laws are different. Some laws are very restrictive or limiting (Austria, Italy, Germany), while some laws are very open and liberal, such as in those Scandinavian countries which are a part of the EU. Most of the laws also define ethical beliefs because the medical treatment with the medically assisted reproduction procedures triggers many ethical dilemmas. The Slovenian Infertility Treatment and Procedures of Biomedically-assisted Procreation Act is in accordance with the Council of Europe Convention on Human Rights and Biomedicine. Legislative solutions, enshrined in the The Infertility Treatment and Procedures of Biomedically-assisted Procreation Act, are identical or very similar to solutions that are part of other EU member states laws.
