Principle and process of IVF
IVF is an assisted reproductive technology, which helps couples who cannot have a natural birth to achieve their fertility aspirations through in vitro fertilization (IVF) and embryo transfer. The principle and process of IVF can be elaborated from the following aspects. 1. In vitro fertilization
In vitro fertilization is one of the core steps of IVF technology. First of all, women receive ovulation induction therapy, which stimulates the simultaneous development of multiple eggs through drugs. Then, after the egg matures, the doctor uses a slender syringe to take out the egg and sperm, and fertilizes the sperm and egg in vitro. Generally, 1-2 sperm are injected into each egg to make fertilization happen.
The fertilized egg will continue to develop into an embryo. This process is usually carried out in a laboratory environment. Doctors will regularly observe and evaluate the development of embryos, and select the most promising embryos for transplantation.
2. Embryo culture
The fertilized embryo will be cultured in the laboratory. The culture environment needs to provide suitable nutrients and growth conditions to promote the normal development of embryos. Doctors will regularly observe the cell division and morphological changes of the embryo, and evaluate the quality of the embryo development.
The embryo culture time is generally 2-6 days, depending on the situation. In the process of culture, doctors will choose the best time for transplantation according to the development of the embryo.
3. Embryo transfer
Embryo transfer is the last step of IVF technology. The doctor will select one or several embryos with the most development potential and transplant them into the female uterus. The transfer process is usually carried out in the operating room. Doctors use long and thin tubes to send the embryos into the uterus.
The process of embryo transfer is relatively simple, generally without general anesthesia. Women need to rest for a period of time after surgery to help embryo implantation and implantation.
4. Follow up monitoring and pregnancy
After embryo transfer, women need a period of rest and recovery. Later, doctors will conduct regular monitoring to see whether the embryo is successfully embedded and whether it develops normally.
If the pregnancy is successful, women need to continue to receive regular prenatal care and care during pregnancy under the guidance of doctors. If the pregnancy fails, the couple can choose to try IVF again, or choose other birth methods.
Summary
Through in vitro fertilization, embryo culture, embryo transfer and subsequent monitoring, IVF technology helps couples who cannot have a natural birth to realize their reproductive dreams. During in vitro fertilization, doctors fertilize eggs and sperm in vitro; The fertilized embryo will be cultured in the laboratory; After the best time is chosen, the doctor will transfer the embryo into the female uterus; Follow up monitoring was carried out after transplantation to observe whether the pregnancy was successful. With the help of modern medical technology and laboratory technology, IVF technology provides a way for couples facing fertility problems to realize their dreams.
