Uncover 7 secrets hidden in the female uterus

　　1. Menstruation comes from Uterus intima

　　The surface layer of the uterine wall is the endometrium, where menstruation occurs. After the menstrual period, under the action of estrogen secreted by the ovaries, endometrial cells begin to grow. On the 5th to 9th day, a thin layer of endometrium covers the entire uterine surface, and then gradually thickens, and the number of uterine glands gradually increases. On the 15th day, the ovary has ovulated, and the endometrium continues to thicken under the stimulation of progesterone, reaching a thickness of 5 to 6 mm. On day 25, if the egg is not fertilized, estrogen and progesterone levels will drop, the glands will shrink, and the lining will gradually become thinner. Eventually, the endometrium loses support and peels off, manifesting itself as menstrual cramps. In the womb, a play like this is performed once a month.

　　2. Why? Dysmenorrhea？

　　10% fertile period female Endometrial reflux will occur and travel along the fallopian tube to the abdominal cavity, ovaries, and even the rectum, causing endometriosis. Local bleeding will occur under the control of hormones every month, leading to inflammation and edema in surrounding tissues, leading to dysmenorrhea. In addition, if the cervical canal is narrowed or the uterine position is abnormal, it will affect the discharge of menstrual blood and cause dysmenorrhea. Dysmenorrhea may also occur due to abnormal uterine contractions caused by uterine fibroids and endocrine disorders.

　　3. Why is the cervix an accident-prone area?

　　The cervix is ​​the connecting channel between the uterus and vagina, and it is also an accident-prone area. The female vagina is connected to the outside world and has more opportunities to be infected by bacteria in life, such as various microorganisms brought by it during sex, the invasion of bacteria after the cervix is ​​damaged after miscarriage, or bacteria infected by bad lifestyle. However, these pathogenic bacteria only reach the cervix and rarely invade the uterus. Because the cervical mucosa secretes mucus, a mucus plug forms in the cervical canal, which isolates the uterus from bacteria. According to research, bacteria can be detected in the lower 1/3 of the cervical mucus plug, but there are no bacteria in the upper 2/3. In this way, the cervix becomes an important gateway to resist external bacteria, which means it will be stimulated by more pathogens.

　　4. The uterus during pregnancy fetus energy

　　In a woman's lifetime, her ovaries will ovulate approximately 400 to 500 eggs. The ovulation time is generally on the 13th to 16th day of the menstrual cycle, or around the 14th day before menstruation. When having sex at this time, the chance of pregnancy is relatively high. On day 15, the egg and sperm After meeting and fertilizing in the fallopian tube, the endometrium is soon notified. The original plan is stopped immediately and continues to thicken on the existing 5mm thickness to make it suitable for the implantation of the fertilized egg. It takes 3 to 4 days for the fertilized egg to pass through the fallopian tube and reach the uterus, choose a suitable implantation location and gradually get close to it. The implantation is completed in 11 to 12 days, and the embryo and the mother's body are integrated.
