Nowadays, with the rapid spread of the Internet, people's understanding of assisted reproduction methods - IVF technology has gone from the previous questioning - understanding - acceptance - with the help of IVF technology to achieve such a process of child-seeking. So what are the steps and timing of fertility for families who are assisted by ivory technology? Complicated? Does it take 3 months for fertility to take? Specific and listen to Hengjian Overseas for your detailed analysis!
The steps of the third generation of test tubes are briefly explained
Hengjian Overseas pointed out that when many IVF families consult about IVF fertility in the early stage, the steps of IVF are bound to be an aspect that will be mentioned. Because, in advance, understand the general steps of IVF fertility, pre-IVF - mid- late, which link needs to do what things, which should be avoided, and strive for IVF once on the IVF pregnancy, no need to carry out secondary IVF, wasting valuable time and energy and money.
1. Preoperative physical examination. Let the IVF doctor understand the patient's recent physical condition, so as to develop a scientific and reasonable and personalized IVF treatment plan.
Tips: Be wary of intermediaries who don't do any checks and let you do test tubes, especially test tube families in Thailand, this is just a marketing tool for intermediaries. Whether it is a domestic test tube or a test tube to Thailand, there are certain indications. Do a good preoperative physical examination, and meet the requirements to do it! Does not meet, need conditioning.
2. Enter the test tube cycle, inject and take medicine, and promote ovulation. Usually on the third day of menstruation, doctors begin to use pro-ovulation drugs, both oral and injectable. Ultrasound of the B ultrasound is monitored for follicle development at 13 days of menstruation.
Then, after the end of ivy tube expulsion, the follicle development is detected. The eggs are then retrieved after 36 hours of injection.
Note: Egg retrieval must meet the conditions and time of follicle maturation, which can provide a IVF success rate. On the day the woman retrieves the egg, the man takes sperm. (If the man can take the sperm and freeze in advance due to work or time factors, as long as he pays a cryogenic management fee)
3. Embryo culture stage. After the combination of sperm and egg fertilization, the blastocyst is cultured by three generations of test tube technology to improve the probability of IVF implantation.
4. Pre-transplant genetic screening stage. Chromosomes are screened and abnormal chromosomes are removed by test-tube third-generation PGD/PGD technology. Achieve good pregnancy eugenics.
5. Embryo transfer stage. According to the fertility needs of the TEST tube family, the transfer of high-quality and healthy embryos to the mother can be done, generally based on singleton transfer, because the risk of twin transfer to the mother and fetus is too large! There is no pain during the operation, and there is no need to get drunk. Note: Observe 14 days after transplantation and see if you have a successful conception by blood test.
Extension: Why are some fresh embryo transplants unsuccessful twice, but frozen embryos are successful once?
In fact, in most of the IVF fertility process, the proportion of successful cases of IVF transplanting fresh embryos in the current cycle is relatively high. In general, the transfer of fresh embryos is not successful, and the most important thing is the embryo itself. For example, low-grade embryos, high embryo fragmentation rates, and so on. In addition, although some families transfer high-grade embryos, the laboratory professional operators cannot judge its internal structure with the naked eye, and the implantation rate may not be as good as that of low-grade embryos, so there is a failure to transfer fresh embryos and a successful transfer of frozen embryos.
Of course, there are also incoordination factors between the intima and the embryo, or some unpredictable factors and so on.
