Cervix in menopause, colposcopy. Menopausal cervix treated with Lugol's iodine solution, used to test for cervical abnormalities. After menopause, the squamous epithelium of the cervix undergoes atrophy, as seen here. Normal cervical mucosa contains glycogen and stains brown, whereas abnormal mucosa, such as eroded areas or early cervical cancer, do not take up the stain. Any abnormal areas can be biopsied and examined histologically. Colposcopy is a medical diagnostic procedure to examine a magnified view of the cervix, vagina and vulva.
