Development process of test tube baby
In vitro fertilization, IVF) is an assisted reproductive technology, which enables couples who cannot conceive naturally to realize their desire to have children by transplanting eggs and sperm into women's uterus after in vitro fertilization. The development process of IVF can be divided into four aspects to elaborate in detail.
Acquisition and treatment of eggs and sperm
During the development of IVF, eggs and sperm need to be obtained and treated first. Before IVF, women need hormone therapy to promote the development and maturation of multiple follicles, and determine the best time to take eggs through ultrasound examination. Then, in the operating room, doctors use ultrasound guided fine needles to puncture the ovary and remove the eggs. At the same time, the sperm provided by the husband and wife should also be treated, including removing the capsule of the sperm head and other non viable sperm.
After the treatment of eggs and sperm, the doctor places the eggs and sperm in an in vitro culture dish for in vitro fertilization. This process simulates the combination process of egg and sperm in the female body, so that the fertilized egg can be successfully formed.
Embryo culture
After in vitro fertilization, the fertilized egg will continue to develop in the culture dish. Provide proper nutrients and environmental conditions in the culture dish to promote the normal development of embryos. Doctors will evaluate the quality of embryos according to their morphology and development, so as to select the best time for embryo transfer.
At present, the development of assisted reproductive technology has greatly improved the quality of embryo culture. In the laboratories of some advanced assisted reproduction hospitals, the culture environment of embryos can simulate the conditions in the human body, such as maintaining appropriate temperature, humidity and pH value. These optimized culture environments can improve the survival rate and development ability of embryos.
embryo transfer
After the embryo is cultured to a specific stage, the doctor will select the embryo with the most development potential for transplantation. The transplantation process is usually carried out in the operating room. Doctors use thin tubes to transfer embryos into a woman's uterus to complete the whole process.
Embryo transfer can also carry out multiple embryo transfer, that is, multiple embryos can be transferred to the uterus at one time. This can increase the success rate of IVF, but also increase the risk of multiple pregnancy.
Embryo implantation and pregnancy
After embryo transfer, embryo implantation is necessary to achieve pregnancy. Embryo implantation refers to the attachment and development of the embryo in the uterus. Women need to take some measures to improve the success rate of embryo implantation, such as maintaining good rest and eating habits, and avoiding strenuous exercise and excessive fatigue.
After embryo implantation, a pregnancy test is performed to confirm whether the pregnancy is successful. If the pregnancy is successful, the subsequent pregnancy process is not very different from the natural pregnancy. The doctor will conduct regular prenatal examination to ensure the development of the fetus and the health of the mother.
summary
The development process of IVF includes the acquisition and processing of eggs and sperm, embryo culture, embryo transfer, embryo implantation and pregnancy. This process requires the meticulous operation and supervision of doctors, as well as the reasonable recuperation and cooperation of women. IVF technology provides a hope for couples who are unable to conceive naturally, enabling them to realize their desire to have children.
