Sun Wukong popped out of a rock, did IVF babies pour out of a test tube? No. IVF babies are also delivered from the mother’s womb. In a naturally conceived baby, the father’s sperm enters the mother’s vagina and uterus and meets and fertilizes the mother’s egg in the fallopian tube to form a fertilized egg. While the fallopian tubes are transporting the fertilized egg, the egg divides and develops into a blastocyst by the time it reaches the uterine cavity. The blastocyst takes root in the lining of the uterus and continues to grow and develop into a fetus, which is eventually delivered as a baby or newborn. In vitro fertilization, the reason why the word test tube is used is because the embryos are cultured in culture fluid without the instruments of test tubes and Petri dishes. In fact, IVF babies have a richer life experience than normally conceived babies, including: 1. The eggs are not ovulated through the ovaries, but are aspirated through puncture needle puncture. There are multiple eggs that develop and mature at the same time, accompanied by many siblings. 2. The semen is optimized and good quality sperm are left behind. The sperm can frolic and swim in the culture fluid very joyfully. 3.Fertilization is divided into two forms: natural fertilization and artificial fertilization. Natural fertilization is like normal conception, where the sperm compete with each other and the smartest and strongest sperm can penetrate the zona pellucida of the egg to complete fertilization. Artificial insemination, on the other hand, involves artificially selecting good-looking, graceful swimming sperm and injecting them into the egg to passively complete fertilization. At this point this is a world that relies heavily on face value. Of course, we still advocate active fertilization, not passive fertilization, and should try to comply with the laws of natural selection. 4, After the fertilized egg is formed, it has to grow and divide in the culture fluid to absorb nutrients and develop into an oogenesis embryo (D3) or blastocyst (D5/D6), with a period of solitary time and a period of group living. 5. Through the transfer tube, we transfer the embryos into the mother’s uterus. The embryos enter the uterine cavity through the cervical canal, rather than being transported through the fallopian tube. 6. Another part of the embryos will be hibernated for months or years, waiting for the mother to provide a suitable warm bed before reviving and transferring. They experience first-hand the hibernation that only occurs in science fiction movies. 7. Eventually, the IVF baby is delivered by vaginal delivery or cesarean section, just like a naturally conceived baby. Below is a graphic representation of the IVF baby’s adventures. You can tell our babies about the different experiences in their lives later!
