Third generation test tube technology, frozen embryo!

Embryo transfer is a key step in the IVF process and the closest to success, so many patients attach great importance to this link. During the IVF period, many patients have to choose frozen embryo transplantation because of physical reasons. Hengjian overseas finishing.

Third generation test tube technology, frozen embryo!

For frozen embryo transplantation, in fact, most patients are worried about its success rate, in the eyes of patients, frozen embryos are not as good as fresh embryos, because frozen embryos have been frozen after all, and their vitality must be much less than fresh embryos. So is IVF frozen embryo transfer really what patients think? Is the success rate of frozen embryo transplantation high?

In fact, the success rate of the two is basically the same, and there is almost no obvious difference. Because the process of forming an embryo in the laboratory requires a certain amount of freezing, but the freezing time of the spare frozen embryo will be relatively long, but the success rate is almost the same.

The success rate of frozen embryo transplantation is not high, mainly to see the following points:

1. The age and age of patients have always been an important factor affecting the success rate, especially in the past 35 years old, the success rate will decrease significantly. Due to age, ovarian function decreases, egg quality and endometrial tolerance decrease. As infertility lengthens, the age of patients increases, and so does the success rate. Therefore, infertility patients should pay close attention to receiving test tubes, so as to seize the time to do frozen embryo preservation, thereby improving the quality of embryos.

2. The number of embryos transferred, relevant studies have shown that the success rate of transferring 3 embryos in a cycle is significantly higher than that of transferring 1-2 embryos. Many people believe that the greater the number of embryos transferred, the higher the success rate, but the higher the chance of multiple pregnancies.

3, the quality of frozen embryos, this may also affect the success rate. The long incubation time is conducive to the selection of high-quality embryos, and the embryos are cultured in vitro for about 20 hours after thawing, so that embryos with fast growth and development speed and good quality can be selected, which is conducive to the successful pregnancy of patients.

In fact, no matter what kind of embryo is transferred, the success rate is the same. In addition, no matter what the reason for choosing frozen embryo transplantation, the patient's body must meet the conditions for pregnancy, so as to improve the success rate.
