Flow of the third generation IVF
IVF technology is an assisted reproductive technology that helps couples who cannot conceive naturally achieve their reproductive aspirations. The third-generation IVF technology is further developed on the basis of conventional IVF technology, which can reduce the risk of inheritance of genetic diseases. The process of the third generation IVF will be introduced in detail below.
Aspect 1: Gene detection and screening
The first step of three generations of IVF is to carry out gene testing and screening for couples to determine whether there is a genetic disease that can be passed on to the next generation. Usually, couples need to go to hospitals or special IVF centers for gene testing. Doctors will take blood samples from couples for gene sequencing analysis. If necessary, couples with diseased genes will also be given genetic counseling to understand the possible risks in detail. After obtaining the genetic test results, the couple can decide whether to carry out the third generation of IVF according to the doctor's advice.
Under the guidance of doctors, couples can choose a regular hospital designated by the country for further operations. For example, some large general hospitals in China, such as Peking Union Medical College Hospital and Xinhua Hospital affiliated to Shanghai Jiaotong University School of Medicine, provide assisted reproductive technology services, including third-generation IVF.
Aspect 2: Egg collection and sperm extraction
Before the third generation IVF operation, women need to inject ovulation promoting drugs to guide ovulation. Then, doctors will puncture the ovulatory sac and collect mature eggs through ultrasound guided hysteroscopy technology. The collected eggs will be immediately frozen by laboratory technology for subsequent operations.
At the same time, men need to provide semen samples. Semen samples will be processed in the laboratory to extract high-quality sperm. The quality of sperm will directly affect the next step of embryo culture and transplantation.
Aspect 3: Somatic cell nuclear transfer and embryo culture
Somatic cell nuclear transfer is one of the core steps of the third generation IVF technology. In the laboratory environment, the original nucleus in the female client's egg is removed, and then the somatic nucleus of an adult in the couple is injected into the oocyte. After specific operation and culture, the egg will enter the growth and development state again.
Next, the embryos will continue to be cultured in a petri dish. After the embryo has reached the appropriate development stage, the doctor will select the healthiest embryo for implantation.
Aspect 4: Embryo implantation and gestation
After selecting the right embryo, the doctor will use a thin tube to transfer the embryo into the uterus of the female client. This process is usually performed through the vagina and does not require surgery.
After transplantation, women need a period of rest and observation. Doctors will regularly check whether the embryo is successfully implanted and monitor the pregnancy. If the woman succeeds in pregnancy, she can continue to have a normal pregnancy until delivery. If not, the couple can try implantation again and continue to cooperate with the doctor for further treatment.
summary
Through multiple steps such as gene detection and screening, egg collection and sperm extraction, somatic cell nuclear transfer and embryo culture, as well as embryo implantation and gestation, the third-generation IVF technology provides an efficient reproductive solution for couples at risk of genetic diseases. However, when implementing this technology, couples need to fully understand the relevant processes and possible risks, and make joint decisions with professional doctors.
