What causes cervical cysts and pelvic effusion?

Uterine cysts are caused by squamous columnar metaplasia of the cervix, cervical damage, and stenosis of the glandular orifice. Pelvic effusion is caused by factors such as poor personal hygiene during menstruation, intrauterine infection, postoperative infection, and peritonitis. Symptoms such as menstrual disorders and lumbar and abdominal pain can occur.
