The uterus is the organ that nurtures the embryo, the fetus and produces menstruation, the passageway for sperm to reach the fallopian tubes after sexual intercourse, and the uterine contractions that expel the fetus during childbirth. 1. Gestation of embryo and fetus: The uterus can gestate embryo and fetus, and is an important place for the growth and development of fetus. Therefore, the uterus can help women fulfill their reproductive functions. After pregnancy, you should take reasonable rest, prevent overwork, and do not do strenuous exercise to avoid preeclampsia. 2. Produce menstruation: Menstruation refers to the periodic shedding and bleeding of the endometrium that accompanies the cyclical changes of the ovaries. The appearance of regular menstruation is an important sign of maturity of reproductive function. 3. The passage of spermatozoa to the fallopian tube after sexual intercourse: after sexual intercourse, spermatozoa enter the cavity of the fallopian tube through the cervical canal and the cavity of the uterus, and the spermatozoa that have been energized meet with secondary oocytes in the fallopian tube, combining to form a fertilized egg. 4. Uterine contractions during labor and delivery: During labor and delivery, the uterus will expel the fetus and its appendages through regular uterine contractions. It can be seen that the uterus is very important to women. It is recommended to go to the hospital for regular medical checkups and any diseases of the uterus should be treated in time. In daily life, you should develop a regular routine, avoid staying up late for a long time, and pay attention to personal hygiene.
