While some experts believe that the tests can harm the embryo, others advocate the technique to increase the pregnancy rate
Genetic Testing in the Embryo
One of the mechanisms for reducing multiple gestational rates, genetic testing in embryos is not consensual. From the technical point of view, they are considered invasive. This is because, for badysis, the embryo must undergo a biopsy, with a laser cut.
"Imagine an embryo with just over two hundred cells, taking four to eight cells, whether you like it or not," said Hitomi Nakagawa, president of the Brazilian Society for Assisted Reproduction. The test, she says, is contraindicated for younger women, who have fewer risks of genetic abnormalities.
Márcia Riboldi, director of Igenomix Brazil, one of the companies that makes the diagnoses, defends the method. "We have 99% accuracy," he says. "With that, pregnancy rates have increased." According to her, the next step is to develop techniques to badyze only the residues left by the embryo – without touching it

Another point of debate is ethical. In addition to chromosomal mutations that would make implantation of the embryo unachievable, the test results from genetic conditions that are not incompatible with life, such as Down's syndrome.
The Federal Council of Medicine (CFM) makes it possible to test the diagnosis of genetic diseases and the elimination of diseases, but does not detail the circumstances in which embryos can be excluded. In a statement, the CFM said that it "remains vigilant" on this issue and said that a "rule update proposal" could be brought before the body's body.
"Genetic testing is a form of eugenics, some human beings do not have the right to life," says biologist and sociologist Francisco Borba, of the Center for Faith and Culture of Pontifical Catholic University of São Paulo (PUC-SP). "It is deprived of the right of the child to be as it is."
