When there is no odor and an abnormal increase in the amount of leucorrhea, it is considered a normal physiological phenomenon. The reason for this is the change in hormone levels in the body of the patient during ovulation, resulting in certain changes in the cervical mucus, resulting in transparent egg-white-like leucorrhea, generally without odor and abnormal increase. Pathological: 1. Ovarian dysfunction: This is caused by hormonal and follicular maturation abnormalities, resulting in dysfunction of the hypothalamic-pituitary-ovarian axis. If the leucorrhea is clear like egg white and increases abnormally, it may be caused by ovarian dysfunction. 2. Vaginal adenopathy: It is mostly caused by the appearance of glandular tissue on the connective tissue of the cervicovaginal area due to the use of non-steroidal synthetic hormones, which often has no obvious conscious symptoms. Physiologic leucorrhea, which is clear and egg-white like, disappears after ovulation. If it is accompanied by other abnormal symptoms, it is recommended to go to the hospital for examination and treatment. Pay attention to your daily personal hygiene, keep your vulva clean and dry, and insist on changing and washing your underwear every day. In addition, the leucorrhea caused by various vaginitis and other diseases, in addition to odor and volume changes, the color and shape will also change, such as mycosis fungoides, chronic endometritis leucorrhea is purulent or bloody.
