Why is there so much leucorrhea?

Leucorrhea is a common substance in women. This substance is generally secreted through the female vagina. Most women with gynecological diseases will have abnormal leucorrhea. Abnormal leucorrhea generally includes leucorrhea odor, brown leucorrhea and large amount of leucorrhea. No matter what the reason is, it means that the woman has a gynecological disease, which is not a good phenomenon for women. So why is there so much leucorrhea recently?

Leucorrhea is a sticky white liquid that flows out of the vagina of women. It is a mixture of secretions from the Bartholin's glands, cervical glands, endometrium, exudate from the vaginal mucosa, and desquamated vaginal epithelial cells. Leucorrhea contains lactobacillus, lysozyme and antibodies, so it has the effect of inhibiting bacterial growth. After marriage, leucorrhea can also lubricate the vagina and facilitate sexual intercourse. The formation of leucorrhea is closely related to estrogen, so pre-pubertal girls generally do not have leucorrhea. After puberty, the ovaries begin to develop and secrete estrogen to promote the development of the reproductive organs, and leucorrhea begins to appear at this time. During each menstrual cycle, the quality and quantity of leucorrhea changes as the secretion of estrogen varies. Generally, the secretion of estrogen reaches its peak between two menstrual periods (equivalent to the ovulation period). Excessive estrogen stimulates the cervical glands to secrete more mucus, so the leucorrhea at this time is abundant, transparent, sticky like egg white, and can be pulled into threads, and the vulva feels moist. After the ovulation of the follicle, progesterone increases and inhibits the secretion of cervical mucus. At this time, the leucorrhea is less in amount and thicker. In the few days before and after menstruation, due to pelvic congestion, vaginal exudate increases, and leucorrhea also increases slightly. Because it contains more exfoliated cells, the leucorrhea is turbid. In addition, the amount of vaginal discharge also increases after pregnancy, during sexual excitement, and after sexual intercourse. After menopause, women's vagina becomes dry and without leucorrhea due to the decline of ovarian function and lack of estrogen in the body. 1) Why is there leucorrhea? Leucorrhea is a secretion from women’s vagina, mainly composed of cervical mucus and vaginal exudate, containing desquamated cells and bacteria from the reproductive tract epithelium.

1. Cervical mucus is the transparent mucus secreted by the glands in the cervical canal. Estrogen promotes its secretion and makes mucus thinner, while progesterone makes it thicker.

2. Vaginal exudate is plasma and lymph fluid that seeps out from the capillaries and lymphatic vessels of the vaginal wall, mixed with desquamated vaginal epithelial cells. There are no glands in the vaginal epithelium, and the pelvic organs become congested and exudation increases before menstruation every month. Both rely on the influence of ovarian hormones. After puberty and sexual maturity, women's ovarian function begins to develop and enters a period of vigorous function, so there is leucorrhea. During pregnancy, the placenta secretes estrogen and progesterone, causing more congestion in the pelvic organs and often increasing the amount of leucorrhea. Young girls and elderly women often have dry vulva and vagina because their ovarian function has not yet started or has declined, their estrogen levels are low, and they have neither cervical mucus secretion nor vaginal exudate.

2) Abnormal leucorrhea 1. Pathological leucorrhea: such as inflammatory leucorrhea, leucorrhea caused by tumors and leucorrhea caused by foreign bodies. Leucorrhea is a mixture of vaginal mucosal exudate, secretions from cervical glands and endometrial glands, secretions from the Bartholin's glands, and secretions from the sebaceous glands of the labia majora and labia minora, with the first two being the main components. Leucorrhea contains vaginal epithelial exfoliated cells, white blood cells and lactobacilli. Leucorrhea can be divided into physiological and pathological types, and their causes and properties are different.

3. Physiological leucorrhea is a white, thin, paste-like liquid, generally odorless. Under normal circumstances, leucorrhea plays the role of moisturizing the skin of the labia and vagina. The sebaceous glands of the labia secrete a viscous milky fluid; the Bartholin's glands secrete a colorless, clear, acidic fluid; the vaginal epithelium has no glands, and its white, thin, paste-like fluid is the exudate of the vaginal mucosa and is acidic; the cervical mucus is alkaline, like egg white; the endometrial secretions are thinner and less in quantity than the cervical mucus. The amount of vaginal discharge varies and is related to age, estrogen levels and congestion of the reproductive organs. After puberty, as the ovaries gradually develop to maturity, the secretion of estrogen and progesterone, the properties and amount of leucorrhea vary with the ovarian cycle. In the middle of the menstrual cycle (before ovulation), due to the vigorous secretion of cervical glands, the cervical mucus component in the leucorrhea increases, resulting in a large amount of leucorrhea, and it is clear and thin like egg white, which facilitates the passage of sperm; after ovulation, the amount of leucorrhea gradually decreases and becomes thicker; before menstruation, due to pelvic congestion, the vaginal exudate increases, and the amount of leucorrhea increases accordingly. After menopause, due to the decline of ovarian function, the decrease of sex hormones in the body, the gradual atrophy of the reproductive tract, the glandular secretion and the exudation of the vaginal mucosa are greatly reduced, resulting in a decrease in leucorrhea. When a woman is sexually excited, a large amount of fluid is discharged from her vagina, which serves as lubrication for sexual intercourse. It was previously believed that sexual excitement was mainly caused by a sudden increase in secretion from the greater Bartholin's glands, but it is now believed that the large amount of fluid mainly comes from increased exudation of the vaginal mucosa. During sexual excitement, the blood vessels in the vaginal wall become significantly congested and dilated, producing a large amount of plasma exudate. Gynecological diseases often cause increased leucorrhea, which has become a symptom of the disease. Its amount and properties are significantly different from normal leucorrhea.
