The white stuff flowing from a woman’s vagina is vaginal discharge, which is composed of mucus secreted from the cervix and vagina as well as epithelial exfoliated cells mixed with it. Normal vaginal secretions are milky white and odorless. During different periods of non-menstruation, the secretions change according to the menstrual cycle, for example, during ovulation the secretions become white, transparent, easily stretched and can be observed under a microscope as lamb’s tooth crystals. However, when the discharge becomes sticky after ovulation, the discharge can form a cervical mucus plug in the cervical canal at this time to prevent bacteria and foreign bodies from entering and causing infection in the uterine cavity, and the discharge at this time can be seen as ellipsoidal bodies under microscopic examination.
