Motherhood is a physiological state of pregnancy that occurs through sexual intercourse, whereby an energized sperm and a secondary oocyte form a fertilized egg in the fallopian tube and settle in the uterus. After the semen enters the vagina through sexual intercourse, it takes about 7 hours for the sperm to move and meet with the secondary oocyte discharged from the ovary in the fallopian tube, where it combines with the acrosome reaction and the zona pellucida reaction to complete the whole process of fertilization and form a fertilized egg. After 6-7 days of fertilization, the embryo is implanted in the endometrium under the conditions of disappearance of the zona pellucida, differentiation of blastocyte trophoblast cells into syncytial trophoblast cells, simultaneous development of the blastocysts and the endometrium in a coordinated manner, and the secretion of adequate amounts of estrogens and motility in the body, i.e., the embryo implants successfully. Therefore, pregnancy needs to complete the above two processes, if necessary, can consult a regular hospital specialized doctors to improve the preparation needs.
