The female leukorrhea is a mixture of the exudate of the vaginal mucosa, the cervical canal and the secretion of the endometrial glands. The formation of leukorrhea is related to estrogen, so you will find that children who have not developed and old women who are menopausal do not have a lot of leukorrhea. This shows that it is related to the action of estrogen. Normal leucorrhea is white and thin, or as thick as egg white, with a small amount, no odor, no fishy smell, and is called physiological leucorrhea. If there is physiological leucorrhea, there is pathological leucorrhea. In case of inflammation of the reproductive tract, such as cervicitis, vaginitis, or when cervical cancer occurs, the amount of leucorrhea will increase significantly, and its nature will change. There are several types of leukorrhea: 1. transparent sticky leukorrhea, which is similar in appearance to normal leukorrhea, but is particularly abundant. 2. grayish-yellow or yellow foamy leukorrhea, which is mainly characteristic of trichomoniasis. 3. bean-like leukorrhea, which is commonly known as mycotic vaginitis. 4. grayish-white fishy smelling leukorrhea It is usually seen in bacterial vaginosis. 5. purulent leucorrhea, which is more yellow, sticky and smelly, is caused by bacterial infection, and is usually seen in acute cervicitis, and some vaginal cancer and cervical cancer co-infection. 6. if it is bloody or watery leucorrhea, you should consider the possibility of cervical cancer, or vaginal cancer or fallopian tube cancer.
