Patients who will be randomized to the control group will be waiting for the ET procedure without any intervention and without any deviation from the standard of care

Exposure to virtual reality environment exposure

IVF Outcomes

Stress Levels

Patients randomized to the study group, will be provided with the VR headset and sensors. The VR exposure will take place before the ET procedure, during their routine pre-transfer waiting period, in a private room. The patient will be able to choose between three different calming VR environments (3 scenes: beach sunset, palm tree patio or redwood forest) and will be exposed to the chosen VR environment for a continuous duration of 15-30 minutes. The VR exposure will be passive, and the patient can control her observation inside the environment by herself, simply by moving her head. During this period, at any time and for any reason, the patient can discontinue the use of the VR session simply by self-removing the helmet

The Use of Virtual Reality Technology in Infertile Women Undergoing in Vitro Fertilization-embryo Transfer: A Randomized Controlled Trial

The difference in CPR (determined by sonographic evidence of a gestational sac and fetal heart rate at 6 weeks' gestation by transvaginal ultrasound) between the study and the control group. An increase of 15% in the clinical pregnancy rate in the study group will be considered as significant.

Will be assessed using the STAI questionnaire (scored 20-80 points). We are expecting a 25% decrease in the STAI scores in the study group to be significant, based on clinical experience with similar patient population

Salivary samples will be collected and analyzed. A 30% decrease in the SAA levels in the study group vs control will be considered significant, based on a previous study

Heart rate & blood pressure measurements. These 2 sympathetic nervous system variables were selected as physical parameters which may indicate anxiety. A significant change between the groups will be based on clinical experience with similar patient populations. An estimated one-third (33%) of the patients would experience elevated blood pressure and/or heart rate readings in the moderate-to-severe range during the standard procedure. VR exposure therapy is expected to reduce this proportion to 20%.
