Hysteroscopy can help clarify the cause of amenorrhea

Most cases can be diagnosed based on typical medical history and uterine cavity examination. Hysteroscopy can show connective tissue floating like floccules in the filled uterine distension fluid, or connective tissue hardening the uterine cavity, pale in color, and scattered between normal endometrium. In severe cases, adhesion tissue forms bands of varying thickness.

(1) Endometrial adhesions: The appearance is similar to the surrounding endometrium. The adhesion tissue is white, highly reflective, brittle, soft, easy to separate, and usually without bleeding.

(2) Muscular adhesion band: The surface is covered with a thin layer of endometrium or glandular openings. A little force is required to separate them, and the broken ends are rough and red.

(3) Connective tissue adhesion band: The surface is grayish white and shiny. The surface is not covered with endometrium, the broken ends are rough and pale, there is no severe bleeding in the cervical os or uterine cavity adhesion, and iodized oil hysterography and hysteroscopy are prone to failure.
