Transfer of blastocysts with IVF.Sensations with successful transfer of blastocysts

In vitro fertilization is increasingly gaining popularity among couples in recent years. To services of reproductologists resort, if for a long time it is impossible to conceive a baby or if fertilization does not occur for some valid reasons. During extracorporeal fertilization, the female body undergoes hormonal correction. One of the important stages of this scheme is the transfer of the blastocyst. It is about him that will be discussed in the article. You will learn how the transfer of the blastocyst takes place in the cryoprotocol, a short or long protocol. Also find out what feelings the woman can experience after him. It is worth noting that the outcome of events can be either positive or negative.

Blastocyst cryostenosis: implantation of

Often when fertilized with a large number of eggs, fertilized embryos are frozen. Usually this procedure is carried out on the third day. However, in the presence of certain conditions, frost can be carried out with a blastocyst. The conditions for storing the embryos with a five-day development are the same as for the three-day periods.

When the need arises for their use, the cells undergo a reverse transformation and are introduced into the womb of the woman. Blastocyst implantation in the cryoprotocol has the same probability as in the conventional one. In this situation, only the conditions for the training of women change.

How is the procedure performed?

After the extraction of the female ovum from the body, their reverse replanting occurs exactly after 5 days. Transfer of blastocysts is carried out, hCG - injection is administered immediately. After that, the woman should be in a state of rest for a while. Most transfers are made under easy analgesia. If necessary, the woman's condition is monitored through ultrasound diagnostics. Can a blastocyst be shared after transference? Theoretically, this is possible. After all, after a cell injection, the cells undergo an important stage - hatching. Only after that they are implanted into the uterus. However, such an outcome of events is very rare.

After manipulation, the patient closely follows her feelings. Also, a woman must comply with the prescribed regimen and take medication. Most of them are hormones. What are the sensations with a lucky coincidence? Consider below.

Blastocyst transfer in IVF: a bit of

theory In the period of preparation for in vitro fertilization, the body of a woman undergoes very heavy loads. Through medications, the ovaries are stimulated. They grow not one or two, but a lot of dominant follicles. Shortly before ovulation, they are extracted using modern medical methods. Further, in special conditions, they are fertilized by male cells.

A few years ago, doctors were confident that it was necessary to attach three-day embryos. This opinion was formed because a day later most of the cells simply died. Laboratory assistants and reproductologists could not create the appropriate conditions for their survival. Now with the help of new techniques and materials, blastocyst transfer can be carried out. This is a set of cells, which for five days developed in a test tube.

Pros and Cons of

Most doctors, geneticists and reproductologists say that blastocyst transfer is about 60 percent of success. While three-day embryos are likely to gain a foothold in the genital organ by only 30 percent. Why is this distinction? Everything is very simple.

Blastocyst after the transfer is ready to immediately infiltrate the endometrium, that is, implant. Three-day embryos with natural fertilization are still in the fallopian tube. To get to the uterus, they need an average of two days. That is why in such situations there is a risk of failure.

The undoubted advantage of blastocyst transfer is a high probability of a successful outcome. However, manipulation has its drawbacks. Some laboratories are not able to create conditions for the survival of embryos in this state. Therefore, some of them die on the fourth day. Reproduction specialists note that the same likelihood of survival would have been in the uterine cavity, if the three-days were planted. Blastocyst is a set of cells, ready to hatch from its shell and implanted into the uterus. At this stage of embryo development, there are more chances to detect any deviations.

Positive pregnancy test

When do the tests after the transfer of the blastocyst go? This question is asked by every woman after in vitro fertilization. You can see the positive result of the pregnancy test right after the manipulation. However, this does not mean that you are pregnant. It is worth a little clarify this situation.

After a blastocyst transplant, a woman is injected with a chorionic gonadotropin injection. This hormone begins to develop independently during natural pregnancy immediately after fertilization. He prepares the endometrium and the uterus for a new state. And it is on him that most pregnancy tests respond. In other words, the study will show you the presence of this hormone in the body. However, this will be only a reaction to the injection. Gradually artificial hCG is excreted, and when the implantation begins to develop its own substance. This happens approximately on the 7-10th day after the transfer. It is then that you can with a probability of 70 percent get the correct result of a pregnancy test.

Toxicosis

Sensations for successful transfer of blastocysts are not much different from usual pregnancy. After implantation, a woman can feel mild nausea and dizziness. Many future mothers complain of weakness and fainting. Also there is engorgement of mammary glands, and their sensitivity is increased. All these are indirect signs of pregnancy.

It should be noted that a woman can sometimes feel all the signs described only because of the development of side effects. After all, the future mother at this planning stage has to take a lot of drugs, most of which are hormones.

How does chorionic gonadotropin behave?

You already know that immediately after the transfer of the blastocyst, an injection is made to the woman containing hCG.If you pass a blood test to determine the hormone for the next day, you will receive an unreliable result. However, immediately after implantation begins to develop its gonadotropin. That is why it is possible to learn about a successful outcome only with regular research. By means of the comparative analysis it is possible to determine, with what speed the hCG level grows or decreases.

Doctors strongly do not recommend conducting such examinations. After all, this can lead to unnecessary stress and stress. A woman after extracorporeal fertilization needs peace and positive emotions. Doctors recommend donating blood for the establishment of a chorionic gonadotropin in it only 10 days after the transfer.

Additional signs of

• If the outcome of events is positive, a woman may feel some other signs. The main one is the absence of menstruation. A representative of the weaker sex knows exactly when the extraction of eggs from her ovaries took place. Bleeding can occur on average 10-14 days after this.
• Drawing pains in the lower abdomen and lower back may indicate a positive outcome or be a sign of rapid menstruation. All these symptoms are very doubtful.
• Discharge from the genital tract with a successful outcome change their character. They become more like a thick cream. The color of the mucus is white or transparent. It is from these secretions that the cork that protects the embryo from external influences and microbes will subsequently be formed.
• The ultrasonic examination can accurately determine the successful outcome. However, it is made only three weeks after the transfer.

Conclusion

You learned about the transfer of blastocysts to IVF.As you can see, with such a technique, the probability of a positive outcome is higher. That's why it's worth to consult with several specialists and find out the scheme of their work. Listen to yourself, and the heart will surely tell you about the positive result of the protocol. Good luck!
