In most cases, uterine prolapse does not affect the normal menstrual cycle in women. However, in very rare instances where the symptoms of uterine prolapse are severe, part of the uterus may prolapse outside the vagina, such as external cervical protrusion. This can cause the cervical tissue to rub against the underwear, leading to local ulcers and even infections. At this point, this can result in the presence of purulent vaginal discharge or bleeding in women. If a woman's immune resistance decreases, the infection can ascend, causing inflammation of the uterine lining. This condition can affect the menstrual cycle, with some women experiencing increased menstrual flow. Additionally, some women may exhibit irregular cycles, irregular vaginal bleeding, and abdominal pain.
