Demystifying three generations of IVF technology!

In medical clinics, the current widely developed IVF technology can be divided into the first generation, the second generation and the third generation of IVF. The first generation of IVF is suitable for the female infertility factor, the second generation of IVF is suitable for the male infertility factor, and the third generation of IVF is suitable for the infertility factors of both men and women. Hengjian overseas release.

The third generation of test tubes is mainly a technique that genetically diagnoses embryonic genes before embryo transfer, with the purpose of preventing the birth of a genetically defective baby.

What kind of fertilization method does IVF use?

In fact, the third generation of IVF is mainly based on the second generation of IVF (ICSI). To put it simply, patients who choose a third-generation IVF need to choose the second-generation IVF fertilization method.

Do I have to raise a sac for the third generation of IVF?

The answer is yes. Patients with a third-generation IVF generation are generally advised to wait for the embryo to be bred to the blastocyst before undergoing a biopsy. So what does biopsy mean? Biopsy is actually taking a few cells from the embryo and sending them for genetic testing. This is usually the trophoblast cells of the biopsy blastocyst, that is, the part of the cell that develops into the placenta.

This part of the cell is biopsyed to minimize damage to the embryo so that it does not affect the healthy development of the embryo. Of course, embryos that develop to the third day can also be biopsyed, but the function of embryonic cells in this period has not been divided, because it is not known which will develop into embryos and which will develop into placenta, so the damage to the embryo will be greater.

Can IVF 3 ensure your baby's health?

Because of the limitations of the development of genetic diagnostic technology and the presence of chimeras during embryonic development, even if the third generation of IVF is done, the baby cannot be sure that it is 100% healthy in the later stage. To avoid missed or misdiagnosed, patients also need to undergo amniocentesis and prenatal diagnosis to ensure the baby's health.
