Summary

The goal of this clinical trial is to assess the use of inhaled nitrous oxide during office hysteroscopy.

The main questions it aims to answer are:

* Does it reduce pain during the procedure?
* Does it increase the success rate?
* Does it improve patient satisfaction?
* Does it reduce anxiety?
* Which populations benefit more (e.g., parity, menopausal status, number of previous surgeries, type and duration of procedure, and type of device)?

Participants will be asked about their pain levels during the procedure, as well as their anxiety levels. All responses will be recorded.

Written informed consent will be obtained prior to initiation.
