Triple IVF babies also need to undergo amniocentesis as prescribed by the doctor to rule out the possibility of chromosomal abnormalities occurring in the fetus. Three-generation IVF refers to pre-implantation genetic diagnosis, which is the use of in vitro fertilization-embryo transfer technology to analyze the genetic material of early embryos and screen out normal embryos for transfer, which can prevent the risk of genetic diseases occurring in the fetus. However, triple IVF also requires amniocentesis under a doctor’s supervision to clarify the risk of chromosomal disorders in the fetus. Amniocentesis is a method of extracting amniotic fluid in the middle and late stages of pregnancy for clinical analysis and diagnosis, which can clarify the risk of chromosomal disorders in the fetus, including structural abnormality or numerical and positional abnormality of fetal chromosomes, etc. The procedure is generally recommended at 16~22 weeks of pregnancy. It is generally recommended to be performed within 16~22 weeks of gestation. After the procedure, proper rest should be taken and changes in vital signs should be closely observed.
