Many people want to do three generations of test tube for various reasons, but there is because of the three generations of test tube technology does not understand and can not start, in fact, this situation can start from the whole process of test tube to understand.

The general process of three-generation test tube is generally the first ovulation, and when the time is ripe, the eggs will be removed, then the embryo will be cultured and genetically screened, and when successful, it will be transplanted to the mother, and finally, the pregnancy test. So, what is the whole process of three-generation IVF? Let's take a look at it together today.

1. Inspection work, ovulation promotion

The examination is half of the success of the test tube, because before doing the test tube, the doctor will analyze which kind of treatment the test tube woman needs according to the test report provided by the test tube woman. The more detailed the examination, the better, so that in the video consultation with the doctor, it is easier to know where the problems of the IVF woman appear, for the success rate of the IVF in the future to do a good job of preparation in advance.

In vitro women need to take the injections according to the doctor's instructions and on time. Don't worry about whether the ovulation pills are harmful to the body or not, the hospital's ovulation pills need to undergo strict testing and can be discharged from the body after a physiological cycle.

2. Egg and sperm retrieval

During the ovulation period, the doctor will monitor the follicle development regularly. When the follicles are mature, the in vitro women need to break the egg injection, and the doctor will retrieve the eggs under the guidance of ultrasound, and only the mature follicles will be extracted.

At the same time when the IVF woman retrieves the eggs, the father-to-be will also retrieve the sperm at the same time. After the semen has gone through a special washing process, it will be placed in a special culture vessel with the eggs in order to naturally combine to form an embryo.

3. Blastocyst, PGDPGS genetic testing

Domestic hospitals usually use embryos that have been cultured to the third day. PGS genetic screening is a screening of all chromosomes of the embryo, which can check whether there is any deletion of chromosome pairs, whether the chromosome morphology and structure are normal, etc. PGD genetic diagnosis can determine whether the embryo carries any gene mutation that may cause specific diseases.

4. Blastocyst Transfer

Blastocysts that have passed the PGDPGS genetic screening can be used for transfer, and the decision to transfer a single or twin embryo is made according to the requirements of the IVF woman, her physical condition, and the condition of her uterus.

5. Confirmation of pregnancy

After in vitro fertilization, blood will be drawn on the 14th day to check whether the pregnancy is successful. During this period, the in vitro women need to keep a good mindset and healthy eating habits to ensure a successful pregnancy.
