Don't worry about the difference between frozen embryos and blastocysts in IVF if you can't conceive naturally. Now the medical level is advanced, and the purpose of pregnancy can be achieved through IVF. In the process of IVF, I believe you will hear some new terms, such as blastocyst and frozen embryo. What's the difference between frozen embryos and blastocysts?
Blastocyst refers to the kind of embryo. Generally, blastocysts are divided into embryos on the third and fifth days, that is, embryos developed in vitro for three to five days. Frozen embryo refers to the state of embryo. These blastocysts are fresh and frozen, and frozen blastocysts are also called frozen embryos. It can be seen that there is not much difference between the two, and they are all the same, except that frozen embryos contain blastocysts.
Generally, when IVF is performed, it is necessary to extract multiple eggs at a time, and there will be multiple blastocysts. If fresh embryos are not transplanted after being cultured into blastocysts, or cannot be transplanted temporarily, then the blastocysts need to be frozen, and frozen embryos will appear.
Both blastocysts and frozen embryos may fail after being transplanted into uterus, which is a question of probability and has little to do with the types of embryos. However, in comparison, it is still recommended that women transplant blastocysts. If there are special circumstances at that time, you need to consult a doctor and take a reasonable transplant plan.
Single blastocyst transplantation, as its name implies, is to transplant a blastocyst. Studies have confirmed that the clinical pregnancy rate of single blastocyst transfer is significantly higher than that of single mitotic embryo transfer. This indicates that blastocyst may be the ideal time to realize single embryo transfer. Blastocyst is an important development stage after cleavage stage embryo, which has undergone morphological changes such as cell fusion, blastocyst cavity appearance and blastocyst cavity expansion. In this process, the development of cleavage stage embryos with poor development potential and abnormal chromosomes will stagnate, and good quality cleavage stage embryos can develop to blastocyst stage. Therefore, selective single blastocyst transfer can not only improve the cumulative pregnancy rate, but also reduce the multiple pregnancy rate and reduce the risk of ovarian hyperstimulation.
The success rate of IVF freezing embryos is very common now, but many couples want their own children very much, so many couples consider IVF. This technology can also be said to benefit many infertile patients, so is the success rate of this technology high? This is what many people care about. Let's take a look at the success rate of IVF frozen embryos.
1. Some studies have found that the success rate of frozen embryos of IVF is about 78%. In fact, from a medical point of view, there is no essential difference between frozen embryos and fresh embryos. Although frozen embryos have been frozen for a period of time, they are still alive as long as they are thawed.
2. Under what circumstances can I be a test-tube baby? There are several situations. The first is bilateral fallopian tube blockage, which will affect pregnancy for whatever reason. The second is the emergence of immune infertility, that is, immunity to semen. The third is the male factor. If the male body is abnormal, he needs treatment. The fourth is that we can't find the cause of infertility. These conditions can be used for in vitro fertilization.
Before this operation, you should adjust your body and mind to the most suitable state. If the time is specific, it must be after menstruation is clean, so pay attention to it. In order to recuperate, you can soak your feet for about half an hour every day.
