"Yes." Cheng yingxuan nodded, "unfortunately, only one of the three embryos left in the last test tube transplantation survived, so you are the only child of your mother."

"I see." Xiaobao asked curiously, "Mom, seven embryos are transferred in three times, and I am the last batch to move into your stomach. After my embryo is matched, where am I when there is no transfer?"

"You were still a small embryo at that time. You were frozen in the hospital and stored in liquid nitrogen at - 196 ℃ for a long time. In other words, my baby, you are the "frozen embryo" thawed and transplanted into the mother's stomach to survive, slowly grow up into a fetus. When it's your turn to move into my stomach, it's all after I "bullied" your father for half a year. " She squatted down and touched his lovely little face. "Little guy, is that enough detail?"

"The medical technology is so powerful now..." Xiaobao a little admire, "sperm can be frozen, embryos can also be frozen."

"Yes." Cheng yingxuan also felt incredible, "and for IVF, these two technologies are very mature."

"Mom, I don't understand..."

"Ask, this palace knows everything."

"Then the prince asked the queen mother, why don't you just put the seven embryos matched out into your stomach at one time, so that in case they all live, they will not give birth to seven twins?"

"You treat your mother and me like a sow?" Cheng yingxuan snorted, "Stinky boy, I'd like to put seven embryos into my stomach at a time, but the doctor only allowed two embryos at a time. After the failure, she continued to" move "two embryos in two months. Twins from pregnancy to childbirth are very risky, more than three fetuses in the stomach grab nutrition, is likely to be stunted, in the process of pregnancy will be stillborn. So, the seven were released three times

"You can only put two embryos at a time? Why did you release three more for the third time? " Curious babies have a lot of problems.

"Because all four of the embryos I put in the first two times failed, and one failed. There are only three embryos left. The doctor said that maybe all three embryos will be put into my stomach. Maybe none of them will survive. Then I will test tube white to do, can't give birth to a baby She gave Cheng Xiaobao a kiss on her face. "Thank you for your tenacious survival in her mother's stomach when two of the last three embryos were hung."

"It should be that I thank my mother for giving me birth." Cheng Xiaobao's expression is very serious, and there is a ray of worry in his glittering eyes, "that mother, I'm such a test tube baby, is it different from other children?"

"Ah Baby, you are a genius. You have the intelligence of a teenager. My mother will explain it to you today... " She said seriously, "ordinary children are children born of their parents' natural reproduction.". The basis of life formation is that after a man and a woman share the same room, the man's sperm combines with the woman's egg to form an embryo. The embryo will swim into the mother's "son Gong" and grow into a fetus. The test tube baby just doesn't need to be roomed by a man and a woman. The doctor takes out the sperm of the man and the egg of the woman to form an embryo. The doctor puts the embryo into the mother's stomach. Then it also needs the embryo to grow into a fetus in the mother's stomach. It also needs to be born in 10 months. "
