The normal form of leukorrhea should be clear, transparent, odorless and in small amounts. Usually, it may increase with the increase of estrogen level in the body, which is a physiological factor and may also be seen in pathological factors such as infections, drugs and diseases.
I. Physiological factors 1, before and after menstruation: leucorrhea changes with the menstrual cycle, when the monthly menstruation is just clean, due to the low level of estrogen in the body, leucorrhea is less. Near the middle of the menstrual period, as the estrogen level rises, the leucorrhea begins to increase. When ovulation occurs, the amount of leucorrhea is the most, as thin as egg white, then the amount starts to decrease again, while the leucorrhea becomes sticky and slightly yellow. The leucorrhea may also increase slightly before menstruation due to pelvic congestion; 2. During pregnancy: the estrogen level in the body rises during pregnancy, which causes an increase in secretion of the cervical glands, manifesting as increased leucorrhea; 3. During intercourse: the vagina and cervix are strongly stimulated during intercourse, and secretions will increase.
Second, pathological factors 1, infection: unhygienic, high-risk sex can lead to bacteria, fungi, trichomonas and other invasion of the reproductive tract to cause infection, resulting in various types of vaginitis, cervicitis, uterine effusion and other conditions, manifested as increased leucorrhea, accompanied by odor, abnormal color, vaginal pain, redness and other symptoms; 2, drug factors: recent application of estrogen drugs will appear transient leucorrhea; 3, tumors. Benign tumors include uterine fibroids, etc. The leucorrhea increases and appears as white plasma, and when combined with infection, the leucorrhea is yellowish watery or purulent and has a foul odor. Malignant tumors include cervical cancer, uterine body cancer, etc. In addition to increased leucorrhea, there are more bleeding symptoms.
