Process and steps of PGD IVF

Test tube baby technology (PGD) is an advanced reproductive technology designed to help couples who want to have healthy babies. The flow and steps of PGD IVF will be introduced in detail below.

1. Gene detection and screening

The first step of PGD test tube baby is to carry out gene detection and screening. This is done by combing the family history of carrying a certain genetic defect, or when a genetic defect is found in the couple. In some specific hospitals, such as the Innovation Hospital in Lisbon, California, the United States, they provide precise genetic testing services, so that couples can know whether the genes they carry are defective before they conceive a baby. This screening process can greatly reduce the risk of some genetic diseases. In this process, doctors will collect blood or tissue samples of the couple and use a series of advanced technologies to analyze genes. These techniques include polymerase chain reaction (PCR), fluorescence in situ hybridization (FISH) and SNP chip analysis. Through these technologies, doctors can determine whether a couple has a disease causing gene or genetic defect, and prepare for the next step of embryo screening.

2. In vitro fertilization

In vitro fertilization is one of the key steps of PGD IVF. In this step, doctors will use in vitro fertilization technology to take eggs from women's bodies and combine them with sperm provided by men in the laboratory. This process is usually carried out under the guidance of gynecological experts, often in some hospitals with advanced equipment, such as Cambridge University Hospital. The fertilized egg is formed after the egg and sperm combine during in vitro fertilization. These fertilized eggs will be cultured in the laboratory until they develop into embryos. Generally, doctors will screen embryos 3-5 days after fertilization to select healthy embryos for further cultivation.

3. Embryo screening

Embryo screening is an important step in the process of PGD IVF. During the embryo screening process, doctors will select healthy embryos without genetic defects for implantation into the uterus. This step is usually carried out in the laboratory and is based on the known genetic information of the embryo. Doctors can use various methods to screen embryos, such as gene sequencing, embryonic cytogenetic analysis, etc. There are many famous hospitals in the world that provide embryo screening services for PGD test tube babies, such as Beth Israel Living Baby Center of Harvard Medical School in the United States. They use the most advanced technology to detect and screen embryos to ensure that only healthy embryos are implanted into the mother.

4. Embryo implantation and pregnancy observation

After embryo screening, healthy embryos selected will be implanted into the uterus of the woman who will become the mother. This is the last step of PGD IVF and the most critical step in the whole process. The doctor will implant the embryo into the mother's uterus at a specific time, and track and observe the pregnancy. During this process, gynecologists will pay close attention to the patient's physical reaction and conduct regular examinations to confirm whether the pregnancy is successful. Doctors also monitor the development of embryos to ensure their normal growth and development.

summary

PGD test tube baby is a technology to help couples conceive healthy babies through gene detection and screening, in vitro fertilization, embryo screening, embryo implantation, pregnancy observation and other processes and steps. These steps have been widely used in many famous hospitals in the world. With the help of PGD test tube baby, many infertile couples have realized their dreams and have their own children.
