In 2012, Dr. Sinya YAMANAKA (Professor of Kyoto University) et al. were winner of a novel prize in physiology or medicine, by the contribution of “induced Pluripotent Stem cell” (iPS cell) creation. This epoch-making iPS cell appearance has given a great shock not only to medical areas positively, but also to psychiatric-psychological areas somewhat negatively, because the latter unexpectedly needed to face with a new problem or new perplexing possibility of human nature and future that urges some change of concepts about human sex, gender, and sexuality. In this paper, the authors have made an attempt to consider and to reconsider the era of iPS cells from the psychiatric-psychological point of view based of our review of traditional understandings of human sexuality. In terms of this context, our theoretical predictive conclusion are as follow : 1)The possibility of realization of artificial human (baby) reproduction by the technical use of iPS cell, e.g. same-sex marriage (homosexual couple) or virgin birth (virgin generation). 2)The possibility of change of standard concept on two-sex reality (male and female, boys and girls, man and woman). 3)The possibility of definitive change of sexual disorders. It’s diagnostic criteria and it’s treatment may be changed carefully by the concept change of human sex, gender and sexuality. 4)For the time being, the human revitalization in the family and family reconstruction will be the most important task of human-being for the sake of protecting human sexual identity confusion. Finally, the authors has described on the status quo and future change of human existence in the times of iPS cell’s appearance and its biological technical application. Some considerations on the theoretical anticipation, namely, the prospect of human-race future has discussed herein.
