Virtual Reality expectations A subset of women (n=50) was asked about their expectations of VR prior to group allocation, using an additional questionnaire with multiple choice questions. Most women expected that VR would be a good distraction from the HSG (78%), while a considerably smaller portion of women (18%) expected VR to reduce their discomfort. Prior to the procedure, 52% of women reported they preferred relaxation exercises, 38% preferred simple movies, while 10% had no preference. Real life movies were preferred over animated movies by 67% (see Supplementary Figure 1a-c). Virtual Reality experience The predefined possible side-effects of Virtual Reality (nausea, dizziness, headache and blurred vision) did not occur more frequent in the intervention group than in the control group. Eight patients removed the VR headset during the procedure because of discomfort (Supplementary Table 2). In the subset of women (n=50) that were asked on their expectations of VR prior to group allocation, some additional, more in-depth questions were asked after the HSG procedure to women in the intervention group (n=26) regarding their VR experiences after they underwent the HSG procedure. All questions used a 5-Point Likert scale ranging from 1 – 5, where 1 represented ‘not at all’ and 5 represented ‘completely/all the time’. Women reported that they were able to concentrate on the VR application between some and most of the time with a mean score 3.19 (SD 0.94). They were distracted by VR between some and most of the time, with a mean score of 3.54 (SD 0.76). Women reported to miss sounds from the VR headset between a little and some of the time, with a mean score of 2.50 (SD 1.30). Over sixty percent (16/26) of women in the subset that had received VR reported that their VR expectations were met. Almost forty percent (10/26) reported that their expectations
