The purpose of this study is to investigate the effect of music therapy on stress levels in female patients applying for in vitro fertilization.

If the patients participate in the study, when they apply to the in vitro fertilization center, they will meet with their anesthesiologist, anesthesia assessment will be done face to face and asked some questions about the diseases that may affect the procedure. . If patients are included in the study, their blood pressure, blood oxygen value and heart rate will be measured and recorded, as in every patient. Subsequently, a test will be administered to assess stress and anxiety levels of the patients. The patients involved in the study will be randomly divided into two groups. One group will be provided with a set of headphones that completely cover the ears and will be played their selected music from a predetermined album for 20 minutes before the procedure. The music will continue to be played through the headphones during the procedure. The other group will be taken to the operating room without any procedure, and this process will be applied to both groups. When patients are brought to the operating room, blood pressure, blood oxygen levels, and heart rate will be measured and recorded once again. Routine anesthesia procedures, applicable to all, will be carried out. After patients are fully awake, their pain condition will be assessed using a visual test.
