To check the scarcity of leukorrhea, we should observe from the quantity, color, texture and smell. Normal leukorrhea should be milky white or colorless and transparent, slightly fishy or tasteless; its secretion, texture by the body of estrogen, progesterone levels of high and low, with the menstrual cycle and the amount of more or less, the quality of the thin and thick cyclic changes. Generally, the amount of leukorrhea after menstruation is small; before ovulation, due to the rise in the level of estrogen in the body, prompting the proliferation of epithelial cells in the cervical glands, the cervical mucus secretion increases, the mucus in the sodium chloride content increases, and can absorb more water, so that the leukorrhea increases in the period of ovulation, the quality of the leukorrhea is dilute, the color of the clear, the appearance of the egg white like, and can be pulled to long filaments; after the period of ovulation, the level of estrogen is gradually low, the level of progesterone rises, and the secretion of cervical mucus is inhibited, and the mucus in the chloride is inhibited. After ovulation, the estrogen level is gradually low, the progesterone level rises, the secretion of cervical mucus is inhibited, and the content of sodium chloride in the mucus is also reduced, so that the leukorrhea at this time has a thick texture, milky white color, and the extensibility becomes poor, and it is easy to break. In addition, there are some physiological phenomena such as pregnancy, oral contraceptives, there will be an increase in the leukorrhea, the reason for which is also related to the changes in the level of estrogen and progesterone in the body. Leucorrhoea scarcity need to be checked Check whether the leucorrhoea is normal, from the amount, color, texture, smell several aspects of observation. Normal leukorrhea should be milky white or colorless and transparent, slightly fishy or tasteless; its secretion and texture are affected by the level of estrogen and progesterone in the body, and there are cyclical changes in the amount and quantity of leukorrhea, and the quality of leukorrhea is sparse and thick with the menstrual cycle. Generally, the amount of leukorrhea after menstruation is small; before ovulation, due to the rise in the level of estrogen in the body, prompting the proliferation of epithelial cells in the cervical glands, the cervical mucus secretion increases, the mucus in the sodium chloride content increases, and can absorb more water, so that the leukorrhea increases in the period of ovulation, the quality of the leukorrhea is dilute, the color of the clear, the appearance of the egg white like, and can be pulled to long filaments; after the period of ovulation, the level of estrogen is gradually low, the level of progesterone rises, and the secretion of cervical mucus is inhibited, and the mucus in the chloride is inhibited. After ovulation, the estrogen level is gradually low, the progesterone level rises, the secretion of cervical mucus is inhibited, and the content of sodium chloride in the mucus is also reduced, so that the leukorrhea at this time has a thick texture, milky white color, and the extensibility becomes poor, and it is easy to break. In addition, there are some physiological phenomena such as pregnancy, oral contraceptives, there will be an increase in the leukorrhea, the reason for which is also related to changes in the level of estrogen and progesterone in the body. If the usual leukorrhea increase for no reason, or accompanied by changes in color, texture, smell, you should be vigilant.
