Endometrium from the menstrual
The surface is the uterine wall lining, menstruation produced here. After menstruation, the ovarian secretion of estrogen, the endometrial cells begin to grow, 5 to 9 days of a thin membrane covering the surface of the uterus, and then gradually thicken, uterine glands gradually increased. Ovaries on day 15 had ovulation, pregnancy hormones stimulate the endometrium to thicken the thickness of up to 5 ~ 6mm. 25 days, if the egg is not fertilized, estrogen and progesterone levels will drop, reducing the gland, endometrium gradually thinning. Finally, loss of support membrane peeling, expressed as menstrual cramps. In the uterus, such plays staged once a month.
Why is dysmenorrhea?
10% of reproductive women endometrium occur upstream, along the fallopian tubes to reach the abdominal cavity, ovary, or even parts of the rectum, causing endometriosis, and hormonal control of each month by local bleeding occurred, resulting in inflammation of the surrounding tissue of , edema, resulting in dysmenorrhea. In addition, if the location of cervical stenosis or uterine abnormalities, will affect the discharge of blood caused by dysmenorrhea, uterine fibroids, endocrine disorders caused by abnormal contraction of the uterus also appears dysmenorrhea.
Why is the accident-prone areas of cervical?
Cervix is the uterus and vagina of the connection channel, is also accident-prone areas. Female vagina and the outside world, in life, the chance of infection by the bacteria more, for example, he brought sex by a variety of microorganisms, bacteria after abortion invasive cervical damage, bacterial infections or adverse lifestyle. However, these pathogens only full length to the cervix, the uterus is rarely violated. Because the cervical mucous membrane secretes mucus in the cervix mucus plug formation, and bacteria isolated from the uterus. It found that cervical mucus plug in the lower 1 / 3 of the bacteria can be found, and the 2 / 3 no bacteria. As a result, cervix becomes a crucial point against external bacteria, which means more pathogens will be stimulated.
Energy of the uterus to the fetus during pregnancy
In the women's life, ovarian ovulation about 400 to 500, usually in the menstrual cycle, ovulation time, the first 13 to 16 days, or 14 days before menstruation is about, this time making love, the chances of pregnancy are relatively high. 15 days, the egg and sperm meet in the fallopian tube, fertilization, endometrial soon be notified immediately to stop the original plan, the existing 5mm thickness to thick, to fit the fertilized egg implantation. Fertilized 3 to 4 days required by the fallopian tubes, uterus to select an appropriate location and gradually close to the implantation, 11 to 12 days to complete the implantation, the embryo and the mother even became one.
How to find your ovulation day?
Women after ovulation, the body will produce a progestin, has elevated the role of body temperature in order to facilitate implantation of fertilized eggs, so we can take advantage of changes in body temperature found in ovulation. Before ovulation the body temperature 36.5 ℃ continued in about fluctuations within the range of 0.2 ℃, which is also called the follicular phase of low temperature; at low end of the day in the morning, there will be 0.3 ~ 0.4 ℃ lower than the day before the body temperature, this day that ovulation has been made. Soon after ovulation the body temperature increased about 0.3 ~ 0.5 ℃, enter the high temperature period, the luteal phase. The high temperature will last around 14 days. If not pregnant, the progesterone secretion decreased endometrial blood loss as the temperature drops, it began a period of cold, and this is the law of temperature fluctuations. Usually in the basal body temperature measured before the morning. The basis of a special thermometer is recommended, more accurate scale, but also significantly different stages of body identification. Accurate measurement of basal body temperature for several months, can accurately predict your ovulation has been made.
Why is there an ectopic pregnancy?
Eggs after discharge, close to the fallopian tube as the umbrella side like a pick up eggs into the egg pick up, and then lining the wall of the squirm and activities with the help of cilia in the fallopian tube to the uterus within the run. If at this moment, also came to the fallopian tube sperm, to complete fertilization and implantation of a fertilized egg into the womb, birth, and growth. If the reproductive organs of inflammation or tumors (such as uterine fibroids), affecting the function of tubal motility, resulting in fertilized eggs run the blocked implantation in the fallopian tube, ectopic pregnancy occurs, 90% of the ectopic pregnancy occurred in the fallopian tube.
Why is vulnerable fetus during early pregnancy?
Survival of the fetus depends on the placenta. Placental villi side, there are numerous small arteries and veins in the uterus wall abuts the inner surface of the collection of small blood vessels in the trunk, to the other side of the focus into the umbilical cord vein and artery, linked to the fetus. It replaces the fetal lung, liver, kidney and gastrointestinal function, bringing oxygen and nutrients from the mother material, and then take away carbon dioxide and metabolic waste. In the placenta, maternal blood and fetal blood separation between the epithelial cells, which is the "placental barrier", making the placenta have a defensive function, bacteria and other pathogens can not epithelial cells.
But the virus and drug can be passed, so the defense function is limited, especially in early pregnancy, mid-placenta barrier is weak, harmful substances will invade the placenta, causing fetal abnormalities. Therefore, four-bogey early pregnancy: avoid the abuse of drugs, avoid exposure to harmful substances, avoid infections, avoid tobacco and alcohol, to prevent certain hazardous substances through the placental barrier and affect fetal development.
