Among the several existing IVF technologies, the first and second generations have always limited success rates because they cannot eliminate diseased embryos; the fourth generation is banned internationally because of complicated ethical issues. In this way, only the third-generation IVF is left. What are the advantages and disadvantages of the third-generation IVF? Hengjian recommends you to choose after reading this article.
The advantages of the third-generation IVF
The third-generation IVF, which is the technology of preimplantation genetic screening and preimplantation genetic diagnosis. First, the female eggs are taken out of the body through surgery, and the first-generation test-tube natural fertilization or the second-generation test-tube sperm injection are used; then the fertilized eggs are incubated for 5 days to form blastocysts for PGS/PGD screening; and finally, the screens obtained Transfer healthy embryos to test tube mothers.
Its first advantage is to eliminate diseased embryos through PGS/PGD, so that these embryos have no chance of entering the mother's body. Without the third-generation test-tube baby, these embryos may be implanted in the mother's uterus, and then a series of serious consequences such as implantation failure, biochemical abortion, early miscarriage or birth of sick children will occur.
Its second advantage is that it can increase the possibility of pregnancy for older families. Because the chromosomes of elderly mothers are very prone to mutations, and the ovarian function has also dropped to a very low level, which is equivalent to having a natural pregnancy but abortion. After the two screening processes of sac breeding and screening, although older mothers can obtain fewer embryos, they can guarantee that there are not so many risks after conception.
Its third advantage is that some families can use it for personalized reproduction. If a couple already has a baby and want a different second child, they can use the PGS technology to check the chromosome arrangement of the embryo and find the X or Y they want.
Disadvantages of third-generation IVF
Its disadvantage is that the cost is relatively high, which is tens of thousands higher than the cost of first- and second-generation IVF. The pre-check stage costs 4-5 thousand yuan; the ovulation induction stage costs 15,000-25,000 yuan; egg retrieval and blastocyst culture cost about 30,000 yuan; embryo screening costs 20,000-40,000 yuan; embryo freezing, every year Cost 6,000; embryo transfer operation costs 12,000.
Moreover, because everyone does test tubes in different regions, if patients go abroad to do test tubes, they will need 60,000 to 80,000 yuan in living expenses. However, for people with better family financial conditions, such "shortcomings" are not considered shortcomings at all, and the couple can easily bear them.
