Six defensive functions of women's private parts

That is the origin of life. We should not be afraid of it and there is no need to avoid it. It should flourish like everything under the sun. The vagina is enjoying a renaissance in the sexual lexicon. A survey on women's private parts concluded that 77% of women would carefully observe their private parts through a mirror, and 53% of women were happy to discuss how to use this area with them. But the frustrating fact is: 45% of women don’t know the health secrets about this part…

Women's private parts have 6 natural defense functions:

1. The labia majora and minora of the female vulva fit together on both sides, covering the vaginal opening and urethral opening like two doors.

2. The female pelvic floor has many muscle tissues. Under the action of these pelvic floor muscles, the vaginal opening is usually in a closed state, and the front and back walls of the vagina are tightly attached, thus resisting the invasion of external pathogenic factors. But for multiparous women, the vaginal walls are relatively loose and this function will be weakened.

3. Estrogen secreted by women's ovaries can promote the proliferation and thickening of vaginal epithelial cells, thereby enhancing resistance to pathogens. In addition, the vaginal epithelial cells are rich in glycogen, and the vagina of normal women is home to a type of bacteria called vaginal Lactobacillus, which can break down these glycogens into monosaccharides and then into lactic acid, making the vaginal environment acidic and maintaining a pH value of 4.2 to 5. Those pathogens that grow well in alkaline environments will be inhibited, which is the self-cleaning function of the vagina.

4. Under the action of sex hormones secreted by the ovaries, the glands of the cervical mucosa can secrete alkaline mucus, forming a mucus plug, which blocks the cervical canal, isolates the cervical canal from the external environment, and reduces the possibility of bacterial invasion. It has been reported that bacteria can be detected in the lower 1/3 of the cervical mucus plug, but no bacteria can be detected in the upper 2/3 of the mucus plug. This shows that cervical mucus plug plays an important role in preventing ascending bacterial infection. In addition, the internal os of the cervix is ​​usually in a closed state, which can also prevent the invasion of pathogens.

5. With the cyclical changes in sex hormones secreted by the ovaries, the endometrium of women of childbearing age also undergoes periodic exfoliation, resulting in menstruation. With the exfoliation of the endometrium and the discharge of menstrual blood, pathogens that have invaded the uterine cavity also have the opportunity to be eliminated.

6. Some of the epithelial cells of the fallopian tube mucosa differentiate into ciliated cells. These cilia can swing toward the uterus. Together with the peristaltic action of the fallopian tube, they can clear away pathogenic bacteria that invade the fallopian tube.
