We know that IVF has been developing for more than 40 years, from the first generation to the third generation of IVF technology, doing IVF is not the higher the number of generations, the better, but according to the personal situation and decide which generation to use! So, how long does it take to do a third-generation test tube? Let's follow Hengjian overseas to learn about it together.
Let's first talk about the steps in the IVF cycle, such as: husband and wife physical examination, documentation, Y material ovulation, egg retrieval, artificial insemination and sacing, PGD/PGS screening technology, high-quality embryo transfer, blood test pregnancy test, etc., so it still takes a while to usher in a good pregnancy.
1. Preliminary inspection stage
Before the IVF cycle, both men and women need to undergo a physical examination, mainly to understand the physical condition and whether it is suitable for IVF fertility. The preliminary physical examination is very convenient, and most of the blood tests can produce results in about two hours on the same day. Individual examination items, due to the need for testing, the result time varies from 2-10 days. After the inspection results come out, if there is no problem, Yisheng will formulate relevant plans according to the results and wait for the cycle to enter.
Second, promote the use of Y
In the IVF cycle, women need to go through the process of promoting ovulation, which can allow the follicles in the ovaries to develop together until they are basically mature, leaving a favorable foundation for the subsequent embryo cultivation process. In order to achieve a high egg acquisition rate, the key point is to grasp the reasonable use of Y time, in order to ensure a healthy basis, to achieve the ideal ovulation effect. When promoting discharge, the doctor will set the duration and dosage according to the different situations of the patient, basically about 10-14 days.
3. Embryo culture
The embryo culture time is about 5-7 days. After the retrieved eggs are fertilized in the laboratory, the cells inside the embryo divide and proliferate rapidly in the following days. The sac-fed embryos form hundreds of cells, are more morphologically stable, and have a high implantation rate. If the patient's physical condition is suitable for the transfer of fresh embryos, the doctor will arrange the embryo transfer time according to the situation. The third generation of IVF is basically frozen embryo transplantation, because PGD/PGS screening is also needed, and the report is relatively slow.
Fourth, blastocyst transplantation
The thickness of the endometrium is ideal (8~12mm), and an important time point that needs to be grasped in the test tube cycle, that is, the time of blastocyst transplantation, only at the right time can the success rate of transplantation be guaranteed to the greatest extent. Implanting healthy and high-quality blastocysts into the uterine cavity can greatly improve the implantation rate and pregnancy rate, and achieve eugenics while caring for the health and safety of mothers and infants. If it goes well, the embryo transfer will be completed within half an hour, and then you can go home after 1-2 hours of observation without abnormalities.
After 14 days of embryo transfer, blood can be drawn for pregnancy testing, and if the HCG value is significantly increased, it means that the pregnancy is already good. It is also possible to go to the hospital for ultrasound examination about 28 days of transplantation to observe the fetal heartbutch and fetal buds to confirm the pregnancy.
Doing an IVF cycle is about 2 months, but you don't need to go to the hospital every day for examination, you just need to make sure that female patients go to the hospital to induce ovulation every day, so pregnant mothers don't have to worry too much about leaving for a long time and consider leaving. Before choosing to do IVF, couples should pay more attention to rest and diet, control their mentality, and strengthen exercise, so that they can better realize their children's dreams.
