OBJECTIVE To assess whether receiving information about twin pregnancy in the form of oral presentation given by a physician could affect the acceptance of single embryo transfer (SET) by couples undergoing IVF. STUDY DESIGN Prospective interventional study. SETTING University hospital IVF unit. PATIENTS One hundred and forty patients (70 couples) undergoing IVF. INTERVENTIONS A questionnaire to measure patients' emotions about twin pregnancy was administered to IVF patients just before and immediately after attending a slide presentation in which the risks of twin pregnancy were explained. Patients scored (1 to 6) ten adjectives linked either to positive or negative emotions; scores before and after presentation were compared. The patients' preference between double embryo transfer (DET) and SET was also registered before and after the presentation. RESULTS The presentation about twin pregnancy caused a significant (p < 0.001) shift of the score distribution toward lower values for positive adjectives referred to twin pregnancy and higher values for negative adjectives. Information impacted similarly on women and men. Despite the relevant change in the emotional attitude, after presentation, 45.7% of women and 48.6% of men were still favorable to DET, whereas 24.3% of women and 37.1% of men preferred SET. CONCLUSIONS Oral information on the risks of twin pregnancy can affect the emotional attitude of patients toward twin pregnancy, but the wish of getting pregnant after fresh embryo transfer overcomes all rational consideration, and the majority of patients still prefer DET.

关于双胎妊娠风险的有针对性的有针对性的信息是否能够提高IVF夫妇对单胎移植的接受度？前瞻性研究。

目的评估是否接受医生以口头形式提供的有关双胎妊娠的信息是否会影响接受IVF的夫妇接受单胎移植（SET）。研究设计前瞻性干预研究。地点大学医院试管婴儿科。患者一百四十名患者（70对夫妇）正在接受试管受精。干预在参加幻灯片演示之前和之后立即向IVF患者发放了用于测量患者对双胎妊娠情绪的问卷，其中解释了双胎妊娠的风险。患者对与正面或负面情绪相关的十个形容词进行评分（1至6）；比较演讲前后的得分。患者的 演示前后都记录了双胚胎移植（DET）和SET之间的偏好。结果关于双胞胎妊娠的陈述导致得分分布朝着双胞胎妊娠阳性形容词的较低值显着（p <0.001）偏移，而对阴性妊娠形容词的分数分布则向较高的值转移。信息对男人和女人的影响相似。尽管情绪态度发生了相关变化，但在介绍后，仍然有45.7％的女性和48.6％的男性对DET有利，而24.3％的女性和37.1％的男性更喜欢SET。结论关于双胎妊娠风险的口头信息可能会影响患者对双胎妊娠的情绪态度，但是新鲜胚胎移植后怀孕的愿望克服了所有合理的考虑，大多数患者仍然喜欢DET。
