On this day, 37 years ago, March 10, 1988 (January 23, 1988 in the lunar calendar), my country's first test-tube baby was born. Zheng Mengzhu, the first test-tube baby in mainland China, was at 8:56 on March 10, 1988. When Professor Zhang Lizhu held the baby's head in her hand and took out the baby,"Wow--wow-", a crisp cry of the baby shocked the medical staff. I was so happy. They couldn't help but exclaim as Professor Zhang, who had worked hard for nearly a year, held this hard-won baby in his arms. Professor Zhang carefully handed the beautiful little angel, weighing 3900 grams and 52 centimeters long, to the pediatrician waiting aside. The pediatrician wrapped the baby and carried it to the mother. Although she was under anesthesia, the pregnant woman Zheng Guizhen was still conscious. She looked at her flesh and blood and nodded frequently, requesting to hug her closer and closer. She said: "According to our custom, children have two names. The name we gave her is Zheng Mengzhu." Meng means germination, which means beginning, because she is our first test-tube baby and the first in our family. We want her to shine like a pearl. We call her 'Yong Long' by her nickname because we went to the Lama Temple for the first time in Beijing and because she was born in the Year of the Dragon." Zuo Geng, the father of the baby who has been waiting outside the delivery room, is also very excited. When he heard the baby's crying, he happily clapped his hands to the crying and said with tears: "We have been born in three generations and have always been hoping to have a child, but we have been infertile after 20 years of marriage. My woman's life is miserable. She lost her parents when she was two or three years old and has been living with her grandfather. Grandpa is 88 years old this year. He can't close his eyes until he sees his children. It's okay now. I'll send a telegram to Grandpa soon." The farmer from Gansu didn't know what to say to the doctors who walked out of the delivery room, but just repeated: "Thank you, everyone!" Looking at this beautiful baby girl weighing 7 kilograms and 8 ounces and her parents, the medical staff became even more excited. Because this beautiful baby girl is not only the crystallization of her parents, but also the result of careful work by doctors. The baby's pink body contains the painstaking efforts of the doctors. Her birth took more than 260 extraordinary days. In May 1987, Zheng Guizhen, a teacher from Yanguan Town, Li County, Gansu Province, arrived in Beijing with a glimmer of hope that her wish to be a mother would be realized. Medical history shows that she has been infertile for 20 years. After examination by Professor Zhang Lizhu of the Department of Obstetrics and Gynecology of the Third Hospital of Beijing Medical University, she was diagnosed with bilateral fallopian tube obstruction possibly caused by tuberculosis, which means that it would be impossible for her to become pregnant. Teacher Zheng couldn't help but shed tears. Professor Zhang, who has devoted his life to exploring the mysteries of human reproduction and women's perinatal health care, understands this sister's feelings very well. Teacher Zheng is not the first patient she has received. Generally speaking, about 10% of infertile couples worldwide, part of which is due to women's bilateral fallopian tubes. What is presented to Professor Zhang at this moment is not only Teacher Zheng's sad face, but also the overlap of the painful and long-lasting faces of many infertile women. She couldn't help but have a strong desire to use her research work on IVF that she had started in 1984 for clinical use. Over the past few years, Professor Zhang and her assistants have repeated the experimental work that must go through for the birth of IVF countless times, and have received the support and collaboration of Associate Professor Liu Bin of the Tissue and Embryology Laboratory. However, it is not easy to actually use it in clinical practice! First of all, the semen of an infertile woman's husband must be basically normal, she can ovulate, and her bilateral fallopian tubes must be blocked. Secondly, even if in vitro fertilization is successful, a maximum of 10% to 30% can be pregnant after embryo transfer. People know that "test tube babies" are not always contained in glass test tubes. Once they are born, they will break out of the wall. It just spends its early stages in a test tube. For this upcoming "initial stage", Professor Zhang made a lot of preparations before finally making up his mind. On June 24, 1987, the cultivation of the first test-tube baby in mainland China began. Professor Zhang first surgically aspirated follicles and obtained 4 mature eggs. Then he took the semen of the woman's husband, washed it twice, and added culture medium. When the upstream reaches of the most active sperm gain the ability to penetrate the egg, it is also the time when the egg is cultured for 5 hours for fertilization. On June 25, after microscopic observation, the male pronucleus and female pronucleus of the fertilized egg could be seen, indicating that in vitro fertilization was successful. Doctors placed the four fertilized eggs into growth medium and continued culture. On June 26, the fertilized egg divided into 3 to 4 cells, and some have divided into 4 to 5 cells. Professor Zhang personally used a special plastic tube to re-implant the fertilized egg through the cervix and into Teacher Zheng's uterus. On July 6, Teacher Zheng was tested and was determined to be early pregnancy. On July 10, Teacher Zheng had early pregnancy reactions. On August 3, B-ultrasound showed that the fetal heart beat, and the life process had begun, which indicated that the clinical pregnancy was successful. The doctors devoted great enthusiasm and effort to the baby. In order to enable her to come to the world smoothly, the hospital specially opened a special hospital bed for her mother. Every day, doctors examined her while still in her mother's abdomen and guided her mother on diet, rest, and activities. On September 1, the fetal limbs were already visible, and a series of subsequent B-ultrasound examinations showed normal growth and development of the fetus, which laid a good foundation for her birth. Her first cry when she came to the world not only showed the birth of a new life, but also showed that China's modern medical technology had achieved a major breakthrough. "Test-tube mother" Yang Fan holds the dragon on her left and the phoenix on her right, and smiles brightly. Professor Zhang Lizhu, a famous obstetrics expert, holds the newborn test-tube baby, Zheng Mengzhu, professor of gynecology, Zhang Lizhu, and Zheng Guizhen, the mother of the test-tube baby, are together. Test-tube babies from all over the country gathered together to celebrate Zheng Mengzhu's birthday
