With the rapid development of society, the improvement of medical technology, many infertility patients use IVF technology to solve fertility problems, many people may have heard of the third generation of IVF, but do not understand the process of the third generation of IVF. So, three generations of test tubes all the process, do you understand? Let's follow Hengjian overseas to learn about it together.
First, the test tube process
1. Preoperative examination
Before IVF begins, the doctor will have both spouses have a physical examination, and the specific items of the examination will vary from person to person. Preoperative examination is done by every IVF family, on the one hand, it allows the doctor to have an assessment of the success rate, and on the other hand, the doctor can formulate a personalized IVF plan according to the patient's physical condition.
2. Ovulation induction
In order to be able to obtain the ideal number of eggs, it is necessary to start ovulation between egg retrievals. Ovulation is the development and maturity of eggs that were originally to be locked in the same cycle. Based on the test, the Y student will determine whether the amount of ovulation stimulating Y needs to be adjusted.
3. Egg retrieval and sperm retrieval
On the day of egg retrieval, the doctor performs a sperm retrieval at the same time. On the one hand, it ensures that the jing eggs are fresh and the fertilization rate is more secure, on the other hand, it can also allow both husband and wife to come to the hospital together and encourage each other. Now we all use painless egg retrieval, and patients do not feel pain during the egg retrieval process.
4. Embryo cultivation and transfer
The process of embryo cultivation is carried out in an embryonic laboratory. After the jing and the egg are combined, a fertilized egg is formed, and an embryo is formed after a few days under the professional culture of the doctor. If we are doing a third generation of IVF, then at this time we can know the number and quality of embryos. After the woman's physical condition is up to standard, the transplant can be carried out.
5. Confirm pregnancy
After 14 days of transplantation, everyone can go to the hospital to perform a scientific pregnancy test. The time for embryo implantation varies from person to person, so before that, it is not recommended that you go to the pregnancy test too early. And premature pregnancy testing will lead to inaccurate pregnancy test results, which is also easy to affect everyone's mentality, it is recommended that everyone be more accurate after 14 days of transplantation.
