title: There are gender differences in attitudes toward surrogacy when information on this technique is provided.
abstract: OBJECTIVE
  We analyzed the data of a nationwide opinion survey reported in a previous study and clarified the importance of socioeconomic status and individual belief on people's opinion regarding the pros and cons of gestational surrogacy. In this study, we analyzed the data of this nationwide opinion survey to identify the effect of providing information about assisted reproductive technology (ART) on the people's attitude towards not only gestational surrogacy but also other ART procedures.
  
  
  METHODS
  This was a cross-sectional study. A nationwide opinion survey on ART was conducted in 2003. The participants included 3647 people (1564 people received only the questionnaire and 2083 people received the questionnaire and a brochure containing information about ART). Multivariate-adjusted odds ratio and 95% confidence interval were obtained using logistic regression models for understanding the manner in which the knowledge about ART affects the attitude of the general population towards ART, which uses donor gametes and surrogacy.
  
  
  RESULTS
  With regard to gestational surrogacy, men in the brochure group could not clearly express their opinions when compared with those in the no-brochure group (odds ratio (OR): 0.69; 95% confidence interval (CI): 0.53-0.89). In contrast, with regard to donor insemination, women in the brochure group could clearly express their opinions when compared with those in the no-brochure group (OR, 1.24; CI, 1.02-1.52). Information about ART, especially in men, promoted disapproval of partial surrogacy (OR, 0.59; CI, 0.44-0.78) and gestational surrogacy (OR, 0.64; CI, 0.48-0.86). On the other hand, for other ART procedures, we found no significant association between receiving information via the brochure and people's attitude towards the technology.
  
  
  CONCLUSIONS
  There were gender differences in attitude toward surrogacy that was affected by providing information about ART. Moreover, determining community attitudes, we observed that a good understanding of the information provided facilitates the expression of a clear opinion, thereby assisting respondents in deciding whether or not they approve of a certain technology.
