Third-generation IVF can not only prolong the female reproductive age, but also select well-developed embryos for transfer, which greatly improves the success rate of normal IVF, but do you know what are the processes for doing third-generation IVF? How long does it take to do that? Today Hengjian Overseas will explain it in detail for you.
Third-generation IVF process
1. Inspection
Physical examination is the basic work of doing IVF, the doctor will judge which treatment method is needed according to the specific situation of the patient, and the more detailed the examination, the greater the help for future treatment. Moreover, at present, the third generation of test tubes in China is not completely open, so sisters who want to do three generations of test tubes in China need more stringent inspection preparations.
2. Ovulation induction
This stage requires injections to allow the body to release more eggs for the next step. The drugs used in this process have been rigorously tested by the FDA and are not harmful to the human body.
3. Egg retrieval
In case of anesthesia, the doctor will retrieve the mature egg.
4, IVF
When the eggs are obtained and the washed tadpoles are removed, they are placed together in a Petri dish for natural binding. When the eggs and the small tadpoles are combined, they continue to be cultured, and when they divide into 6 to 8 cells, one of the cells is extracted for PGD detection.
5. Embryo screening
This process is different from first- and second-generation IVF techniques, which can screen bad embryos, leaving behind high-quality embryos of high grade.
6. Embryo transfer
After blastocyst screening, depending on the patient's condition, select one of the healthy ones to transplant into the uterus.
7. Confirm pregnancy
After about 14 days after the transfer, the hCG is measured for luteal support to determine whether there is pregnancy, and the embryo development is checked again on the 21st day after the transfer, with or without a fetal heartbeat.
The best way to do the third generation of IVF is to combine their own physical conditions to choose the program, the current third generation of technology is more mature, the success rate has a better guarantee.
So how long does it take to do a three-generation test tube?
From the process, we can see that the test tube is generally divided into 2 stages before transfer (examination and use of Yao, etc.) and after transfer, pre-transplant examination to promote ovulation sperm retrieval and embryo cultivation screening takes about a month, after 14 days of transplantation, the pregnancy result is known. If you are not successful, you don't have to be discouraged and sad, you can also perform frozen embryo transfer; even if you don't have frozen embryos, you can also recuperate your body and re-enter the next IVF cycle, so that it may take a long time.
In general, IVF takes one to three months to quickly, because some patients have good health and a successful time, the time required is relatively short, and some patients may need to be successful twice, so this technology requires multiple eggs to be taken at the same time to ensure that there are embryos that can be retransted.
