Outpatient or office hysteroscopy has become the 'gold standard' for the investigation of the intrauterine abnormalities. This minimal invasive modality provides brilliant and clear visualization of the entire uterine cavity and besides this, by the operative channel, minor procedures may easily be performed in the office setting which is priceless for the gynecologist. However, pain related to the procedure may make the procedure uncomfortable for the patient and the physician. Together with the operative time, hysteroscope diameter is considered as the main factor influencing pain. The pain perceived during hysteroscopy may be reduced by using a smaller diameter hysteroscope or by using anesthesia, which decreases pain perception.
