In addition to the chromosomal abnormal translocations we know about, third generation IVF technology PGD can avoid nearly 100 genetic disorders. Advanced reproductive medicine research has pushed the self-control of human reproduction to new limits. The first generation of IVF technology addressed female induced infertility; the second generation of IVF technology addressed male induced infertility; and the third generation of IVF technology has made a revolutionary breakthrough by helping humans choose the healthiest offspring from a biogenetic perspective, offering future parents with genetic disorders the opportunity to have healthy children. This is the third generation of IVF technology, known as pre-implantation genetic diagnosis (PGD), or pre-implantation genetic diagnosis, or third generation “IVF”. It is mainly used to check whether the embryo carries genes for genetic defects. It is based on IVF technology, where the sperm and egg are combined in vitro to form a fertilized egg, which develops into an embryo that is genetically tested before implantation in the uterus, in order to avoid some genetic disorders and to improve the success rate of IVF. A healthy egg cell contains 46 chromosomes arranged in 23 pairs, but before the egg cell can be fertilized, it undergoes a meiosis in which each pair of chromosomes is split in two and the unwanted set of 23 chromosomes is expelled from the egg cell to form a structure called a polarbody. It can be used to identify the sex of the embryo, analyze the chromosomes of the embryo, and then transfer a genetically normal embryo to achieve eugenics. Some people also use third generation IVF technology to conceive twins. This preconception genetic diagnosis (PGD) embryo analysis technique has been used for several years to identify fetuses that have a history of genetic disorders in their parents for signs of unhealthiness, such as gallbladder fibrosis or hemophilia, among others. It actually focuses on genetic diagnosis before embryo implantation, after in vitro fertilization to obtain embryos. With 1/5D1/4 of the population suffering from genetic disorders, each carrying an average of 5D6 recessive genes, being able to identify the presence or absence of genetic disorders before embryo transfer would greatly improve the quality of the baby after birth. Of course, this is easier said than done. There are more than 4,000 genetic disorders worldwide, and up to 73 genetic disorders can be screened and detected through the use of third-generation IVF technology.

Addison’s disease (with cerebral sclerosis) 2. adrenal cerebral leukodystrophy 3. adrenal hypoplasia 4. hemoglobinopathy (Bruton type) 5. hemoglobinopathy (Swiss type) 6. ocular albinism 7. albinism-deafness syndrome 8.
