What Happens to the Cervix During Pregnancy?

The cervix is one of the important tissues and organs in the female reproductive system. From the embryo and the female fetus to the old pupa, the cervix is related to the prevention and care of diseases such as gynecology, obstetrics, family planning, women's health and reproductive health in a woman's life. Women's own health, family happiness, economic and social issues are also closely related to sexuality and reproduction. The cervix can have a variety of diseases, including embryonic abnormalities, inflammation, tumor-like lesions, benign tumors, malignant tumors, injuries, cervical infertility, family planning, assisted birth technology, cervical sex, cervical pregnancy, cervical dystocia, etc. Many obstetrics and gynecology problems. The cervix is an important line of defense to prevent pathogens from entering the internal genitals, but it is also being attacked by various pathogenic factors (female delivery, abortion, surgical injury to the cervix, etc.); and the cervical endometrium has many wrinkles and bacteria lurk It is more difficult to eliminate here and later, and it is easy to cause cervical inflammation. The disease can be divided into two types, acute and chronic. The latter is often caused by the failure to cure the former in time. Chronic cervicitis is more common clinically. The most obvious symptoms are viscous white mucus or purulent Increased yellow viscous leucorrhea, in addition to vulvar itching, lumbosacral pain and so on. ^[1]

Cervix

The cervix is located in the lower part of the uterus and is 2.5 to 3 cm long.

The cervix protrudes from the vagina and contains glands that secrete a type of mucus, namely

What are the effects of cervical abnormalities on fertility ?

The impact of cervical abnormalities on fertility : viscous uterine mucus, viscous mucus will cause a great deal of heterosexual movement of sperm. Generally, mild cervical erosion in women has little effect on fertility. However, cervical erosion will affect the pregnancy in the middle and late stages, and the viscous secretion prevents the sperm from entering the cervix.

The impact of cervical abnormalities on fertility 2: Secretion effects, because the patient's cervical erosion will cause a large number of white blood cells and disease-causing viruses in secretion 5, these white blood cells and viruses will not only make the patient's

The vaginal microbial flora mainly resides in the mucous membranes and folds of the vaginal sidewall, followed by the vaginal fornix and the cervix. The number of viable bacteria in the vaginal discharge of healthy women is 100 to 100 million / ml. At present, the most important member of the normal vaginal flora is Lactobacillus, which can reach 80 million per ml. Its function is mainly to protect the vagina from foreign bacteria. It is the "health guard" of the vagina, so medically The vaginal secretion pH4 is often used to determine the cleanliness of the vagina and to judge the self-cleaning function of the vagina.

Observe the cervix for lumps, erosions, ulcers, polyps, whether the size of the cervix is normal, whether the surface is smooth, whether the texture is too hard, and whether there is uterine prolapse. The perimeter of the normal cervix is raised with a hole in the middle. The parturient is round, the parturient is "I" shaped, tough, red meat, and smooth. If the examination is normal, it means light, quality, no itching and so on. If abnormalities are found, the scale of erosion (light, medium, and none), the degree of cervical hypertrophy, and the size and location of neoplasms will be described in detail. In general, routine gynecological examinations include examinations of the vulva, vagina, cervix, and uterus for size, shape, and location, as well as for fallopian tubes and ovaries.

The healing process of cervical erosion is generally divided into two forms. One is that squamous epithelium near the erosion surface grows under the columnar epithelium that covers the erosion surface, gradually moves the columnar epithelium, and finally replaces the columnar epithelium to cover the entire erosion surface. This is Form covered directly by squamous epithelium; another form is indirect replacement. Under normal circumstances, there are fewer round cells under the columnar epithelium, called reserve cells. These cells have a certain ability to proliferate and differentiate. These reserve cells continuously proliferate and differentiate into squamous epithelial cells instead of columnar. Epithelial cells cover the entire erosion surface, so that the erosion surface is covered by the squamous epithelium again and heals. During the healing process, the newly formed squamous epithelium is often scattered in the form of flakes, or walks in the form of a cord in the erosion surface. Because this new squamous epithelium is born on tissues with inflammatory changes, it easily falls off. Once irritation occurs, erosion reappears. The repeated appearance of repair and shedding is the reason why erosion is not easily cured.

1. Cleanse yourself and prevent sexual disorder;

2. Perinatal health care to prevent uterine detachment;

3. Pay attention to menstrual hygiene and vulvar hygiene. Do not abuse the cleaning liquid for medicinal use.

Uterus-The uterus is located in the center of the pelvic cavity and has an inverted pear shape. It is flat on the front and slightly protruding on the back. The adult uterus is about 7-8 cm long, 4-5 cm wide, and 2-3 cm thick. The volume of the uterine cavity is about 5 ml.

First, do a good job of cleaning. Keeping the vulva clean and dry and preventing infection is the most basic measure for women to prevent uterine fibroids. Cleaning the vulva can prevent pathogens from entering the uterus and causing uterine fibroids ^[4] .

Second, active contraception. Induced abortion can seriously damage the uterus and increase the risk of uterine fibroids in women. Therefore, in life, good avoidance measures should be taken to reduce the number of abortions, because the number of abortions will bring certain harm to the patient's uterine repair, stimulate the normal repair of the uterus, and easily lead to the incidence of uterine fibroids.

Third, reduce high-fat diets. Studies have shown that high-fat foods can promote the secretion of female estrogen after entering the human body, cause a certain stimulating effect on the uterus, stimulate the normal repair of the uterus, and cause uterine fibroids. Therefore, female friends should adhere to a low-fat diet in life, drink plenty of water, and avoid spicy and irritating foods.

Fourth, appropriate control of sexual life. Too much indulgence in sexual life will bring hidden dangers to uterine health, especially unclean sex life, which can cause pathogens to enter the uterine cavity through the vagina, causing endometrial infection and causing uterine fibroids.
