In Chosun era (1392-1910), because of Confucian morals, it had been regarded as the most important obligation toward ancestors to give birth to the son to carry on the paternal family line. The 'yang-ban' (the governing classes in Chosun era) nobleman who had not been blessed with his male heir to hold the Confucian service for his ancestors employed a 'ssi-baji' woman to have sexual relations with him on behalf of his lawful wife unable to conceive in order to make her bear his son. She had secretly borne a baby boy in order to hand over it to him after giving birth, pretending that his lawful wife had borne his son. A 'ssi-baji' woman who was a surrogate mother giving birth to a male heir "by profession" for a respectful 'yang-ban' family got a lot of reward such as arable land when she had borne a baby boy. However, she could not get anything but a bite of grain as the expenses for bringing up her child if she had borne a baby girl. The baby girl was taken home together with her and her daughter also became a 'ssi-baji' woman like as her mother. The social status and occupation of a 'ssi-baji' woman had been succeeded by the maternal line, and 'ssi-baji' women who rent out their wombs to live had been actually existing until before the liberation from Japanese colonial rule. In my paper I'll examine the historical backgrounds that a 'ssi-baji' woman who was not a secondary wife but a professional surrogate mother giving birth to a male heir had been needed among respectful childless 'yang-ban' families in Chosun era. In the age of Chosun-Dynasty, it was actually impossible for respectful 'yang-ban' family member to divorce or keep a mistress even though his lawful wife was unable to give birth to a son be-cause of the reputation of his family. In those days the descend-ant whose mother was a mistress had been prohibited from holding a government post even if his father was a 'yang-ban' noble-man. It was no use keeping a mistress in order to obtain his son, for his descendants from the illegitimate would have no chance of success in 'yang-ban' society. Therefore, in the 'yang-ban' society in Chosun era that paternal line had been highly estimated, a 'ssi-baji' woman of noble descendent blood whose biological father was a 'yang-ban' nobleman and whose origin didn't surface was suitable for a surrogate mother of a respectful 'yang-ban' family's male heir. Although the class system in Chosun Dynasty was officially abolished in 1894, a 'ssi-baji' woman, as a means of obtaining son, didn't actually disappear in Korea where 'son-preference' due to Confucian tradition since Chosun era had been deeply rooted. Since 1950s infertility treatments such as artificial insemination or in vitro fertilization have been introduced in Korea, gestational surrogacy with these infertility treatments have come to be carried out by a surrogate mother so-called 'a present-day ssi-baji' woman, in place of a former 'ssi-baji' in Chosun era. The technology of infertility treatments have made it possible to conceive without sexual intercourse, and recently highly developed assisted reproductive technologies have made it also possible to 'rent' only a womb in order to bear a baby boy with sex-selection technology of IVF (in vitro fertilization) surrogacy. The development of assisted reproductive technologies has made a former 'ssi-baji' woman in Chosun era change into 'a present-day ssi-baji' to rent her womb and bear a baby boy which is not related to her by blood, a literal 'womb for rent', which has been causing serious bio-ethical problems on surrogate mother-hood in contemporary Korea. In my paper I'll study these bio-ethical problems on the 'ssi-baji' surrogate motherhood in contemporary Korea from the standpoint of ethnology.
