In the treatment of the in vitro cycle, the embryos are classified as fresh embryo transplants and frozen embryo transplants according to the circumstances of the embryos. In the case of frozen embryos, the thawing is the way to re-transplant frozen embryos after recovery, while many are concerned that the re-recovering of the embryos after refrigeration can have an impact on the quality of the embryos and lead to their bed failure. Does the tundra transplants have an impact on the quality of the embryos?
In the treatment of in vitro babies, since there is only one dominant ovulation of the natural menstruation cycle, and the availability of eggs is not sufficient to help increase the likelihood of pregnancy, reproductive specialists will grow the basic ovaries in their ovaries through the application of drugs, thus increasing the availability of eggs.
As a result, more eggs and sperm are fertilized, and more embryos are nurtured, so that better embryos can be selected for transplantation among these embryos, thus increasing the bed rate.
However, the in vitro growth of the embryo for three to five days was already the limit and could not continue to be nurtured and therefore had to be discarded. However, it was not only a waste, but also a loss, of the embryos that had not been easily acquired, and it was therefore suggested that they should be preserved by freezing.
Among the liquid nitrogen at 196°C, the embryo was able to freeze rapidly and temporarily stop its development, thus preserving “power” to a greater extent. When needed, the thawing recovery returns to the state of a fresh embryo, with bed and development in the uterus. Embroidery refrigeration technology has not only increased the utilization of embryos, but has also significantly reduced the loss of patients and, to some extent, saved the cost of promoting re-egging.
The current state-of-the-art ultra-temperature fast-refrigeration technology, i.e. glassization, is used to bring the embryo ‘ s temperature down in seconds to 196°C below zero. Because of the rapid rate of freezing, the water in the embryo does not have time to form ice crystals, does not cause any damage to the embryo ‘ s cells and activity, and is subsequently stored in liquid nitrogen at 196°C, at which point the embryo ‘ s cell will not be active.
According to the data, embryo-refrigeration technology could allow the embryo to survive by 99 per cent, so that it would not only reduce the quality of the embryo, but would instead make it better to preserve it and extend its useful life.
Moreover, according to a large number of cases, the rate of pregnancy was not the same as that of a cold embryo transplant and, in some cases, slightly higher than that of a fresh embryo. For patients whose physical condition was not suitable for transplantation, the cold embryo transplanted gave more time to adjust the utero environment, more favourable to the bed of the embryo and significantly increased the rate of in vitro pregnancy.
For infertility patients, anxiety, depression, loneliness, fear, despair and even despair often surround them. This nervous state of mind may affect the outcome of an in vitro baby ‘ s pregnancy. So the test tube baby parents have to learn to depress themselves in the process.
