Among the increasing number of infertile couples today, the good news for them is assisted reproductive technology. Artificial insemination, in vitro fertilization, surrogate mother, preimplantation diagnosis and prenatal testing, and cryonics are assisted reproductive technologies. The development of assisted reproductive technology for infertility treatment has caused many ethical controversies. This study examines these ethical controversies and attempts to clarify the views on the ethical controversies from the bioethical standpoint of the Family Federation for World Peace and Unification. Artificial insemination replaces sexual intercourse with artificial medical technology. In vitro fertilization, the process leading to pregnancy is overly artificial, and the birth of life takes place in a ‘cold test tube’. Throughout the entire process from egg retrieval to implantation, the female body is instrumentalized and alienated as a tool for childbirth. In the process of in vitro fertilization, many fertilized embryos are inevitably discarded, and selective abortions occur. Artificial insemination with donor’s semen or non-partner in vitro fertilization causes the separation of genetic and social fathers, of genetic mothers and social mothers, and of genetic parents and social parents. It comes as an obstacle to the emotional bond between parents and children. In the case of using a surrogate mother, the positioning of the ‘maternity’ becomes more complicated. Preimplantation diagnosis or prenatal diagnosis promotes artificial abortion due to eugenics approach and leads to a ‘designed baby’. The FFWPU’s basic ethical position and exceptional position were presented. First of all, it was clarified that pregnancy and childbirth through assisted reproductive technology were basically unethical contrary to the law of nature, and the exceptionally permitted views were presented.
