Japanese attitudes toward assisted procreation.

CONCLUSION: Based on the present results, the following points are suggested: First, there are significant attitudinal differences [in Japan] on new reproductive technologies between infertile couples and married laypersons; laypersons' attitudes were not so affirmative as those of infertile couples. Second, among the group of infertile couples, male respondents showed more affirmative attitudes toward assisted procreation than female respondents. Third, the main reason for approving of new reproductive technologies was that "it is a treatment for infertility," while the main reasoning of those who disapproved of them was that "it conflicts with the way of nature."
