Embryo screening technology
Embryo screening technology is an important step used in the IVF program to evaluate and select the most healthy potential embryos for implantation. Embryo screening technology usually uses embryo growth and genetic analysis to judge the quality and genetic status of embryos.

First of all, the evaluation of embryo growth is based on the morphological observation of embryo development. Doctors evaluate the quality of embryos by observing their development in culture dishes. Healthy embryos usually undergo normal cell division and tissue formation according to specific schedules and development milestones. The embryos whose development is lower than expected may have some defects or abnormalities, which are not conducive to successful pregnancy and healthy birth.
Secondly, genetic analysis is also widely used in embryo screening to detect whether embryos carry some common genetic diseases. This can be achieved by sampling a small number of cells in the embryo and then performing gene testing. In some cases, if the parents have some genetic disease, doctors can use specific genetic analysis methods, such as polymerase chain reaction (PCR) or fluorescence in situ hybridization (FISH), to detect the genetic status of the embryo.
Finally, embryo screening technology can also use biochemical or physiological methods to assess the sensitivity of embryos to certain specific diseases or genetic risk factors. For example, the risk of diseases such as polycystic ovary syndrome can be assessed by measuring the number of chromosomes in the embryo or the hormone level of the embryo.
The whole process of embryo screening needs to be carried out in the laboratory, usually on the third to fifth days of the IVF cycle. Doctors will carefully evaluate the quality and genetic condition of the embryo, and then select the embryo with the most healthy potential for implantation.
Embryo freezing technology
Embryo freezing technology is a commonly used method of embryo preservation in IVF program, which allows embryos to be preserved when needed and used for future implantation. Embryo freezing technology can provide more opportunities for those patients who cannot implant all healthy embryos in the current cycle, and can also provide patients with the choice to pursue multiple pregnancies.
In the process of embryo freezing technology, doctors transfer the selected embryos to a special freezing medium, and control the cooling rate to gradually cool the embryos to extremely low temperature. Liquid nitrogen is usually used to hide embryos at a temperature of minus 196 ℃ to prevent cell damage during freezing. During the freezing process, doctors also need to add special protective agents, such as mannitol and acidic liquid, to reduce the probability of cell damage.
When the patient is ready for embryo implantation, the frozen embryo will gradually thaw. The doctor will adjust the thawing speed to ensure the safety of the embryo. The thawed embryos were cultured and evaluated for a period of time, and then the embryos most suitable for the patient were selected for implantation.
One of the advantages of embryo freezing technology is that embryos can be stored for several years or even longer, so that patients have more time to decide whether to implant. In addition, the implantation cycle of frozen embryos is relatively simple, without too much drug treatment and egg collection process, reducing the body's pressure and burden on drugs and surgery.
