Risk perception of pregnancy promotes disapproval of gestational surrogacy: analysis of a nationally representative opinion survey in Japan.

Background: To clarify the relationship between the general attitude towards gestational surrogacy and risk perception about pregnancy and infertility treatment.

Materials And Methods: This study analysed the data of nationally representative cross-sectional surveys from 2007 concerning assisted reproductive technologies. The participants represented the general Japanese population. We used this data to carry out multivariate analysis. The main outcome measures were adjusted odds ratios and 95% confidence intervals from logistic regression models for factors including the effect of pregnancy risk perception on the attitude toward gestational surrogacy.

Results: In this survey, 3412 participants responded (response rate of 68.2%). With regard to the attitude towards gestational surrogacy, 54.0% of the respondents approved of it, and 29.7% stated that they were undecided. The perception of a high level of risk concerning ectopic pregnancy, threatened miscarriage or premature birth, and pregnancy-induced hypertension influenced the participants' attitudes towards gestational surrogacy. Moreover, this perception of risk also contributed to a disapproval of the technique.

Conclusion: Our findings suggest that a person who understands the risks associated with pregnancy might clearly express their disapproval of gestational surrogacy.
