At our hospital, an embryologist explains to patients the steps involved in ART and the growth situation of an embryo on day 5. However, this explanation takes a long time and patients must wait to receive it. Therefore, we conducted a survey to investigate: whether these explanations are actually useful to patients, how much of the content do patients actually understand, the level of demand for explanations, and points for improvement. We distributed a questionnaire created by our hospital for wives and for husbands to 140 couples (280 individuals) who underwent ovum pick-up or cryopreserved blastocyst transfer between January 2013 and June 2014. Multiple responses were possible, and the results were examined for each question item. A total of 147 questionnaires were recovered: 43 from husbands and 104 from wives (recovery rate: 52.5%, 147/280). Of the 106 patients who had received an explanation of ART before ovum pick-up, 100% responded that the explanation had been beneficial. Of the 106 patients who had received an explanation 5 days after ovum pick-up, 94.2% responded that the explanation had been beneficial. This indicates that many patients require an explanation from an embryologist.
