Which has a higher success rate, frozen embryo or fresh embryo

All are similar, fresh embryos have not undergone the process of freezing, resuscitation, etc., and the activity is high, but the mother may affect the intrauterine environment due to the influence of a series of drugs such as stimulation and egg retrieval, and then affect implantation.

Which has a higher success rate of transfer, fresh embryo or frozen embryo? The reproductive doctor told the truth.

It is better to freeze embryos.

Fresh embryo or frozen embryo transfer, in fact, there is no good or bad between these two methods. Which method to choose, after the egg is retrieved, the woman's uterus must be examined again to confirm whether the embryo is fresh or frozen. In fact, implantation of embryos in a fresh cycle does not necessarily increase the chances of successful implantation.

In addition to the quality of the embryo itself, the acceptance of the endometrium is also very important. In the fresh implantation cycle, because a large number of ovulation-inducing drugs are used before egg retrieval, the concentration of hormones in the body will be much higher than the general physiological state, and when the concentration of these hormones is too high, it may cause early maturation of the endometrium, changes in endometrial gene expression, etc., which may affect embryo implantation.

Theoretically, yes, but it also depends on the hospital laboratory, if the resuscitation is not done well, it will still cause some damage to the frozen embryo, in fact, it also depends on the quality of the embryo itself, if the good embryo is usually frozen after the resuscitation, the quality is still very good, and even the upgraded embryo will have a higher success rate than the fresh embryo.

Fresh embryos are of better quality and less damaged. In the process of embryo freezing and resuscitation, if the operation is improper or the freezing time is too long, the temperature is too low and too high will damage the embryo. Although the quality of fresh embryos is better, it may also cause the implantation failure of female friends due to the impact of the artificial cycle on women.

Frozen embryos are usually in a natural cycle, and embryos may be more likely to implant.

IVF embryo transfer is a very important process and can be said to be the core part of real IVF. The embryos are divided into frozen embryos and fresh embryos, and in terms of embryo transfer, they are divided into fresh cycle transfer and freeze-thaw embryo transfer. The former is the direct transfer of embryos into the uterine cavity after egg retrieval, in vitro fertilization, and embryo culture.

In the latter, embryos are frozen after they have been cultured and the embryos are cryopreserved. The process of thawing embryos for resuscitation and then transferring them into the uterine cavity at a specific point in the menstrual cycle after the egg retrieval cycle. The main difference between the two embryos is freezing.

At present, in the IVF industry, it is better to transfer frozen embryos or fresh embryos for IVF embryos. So far, nothing has been very clear-cut.

It should be that when the fresh embryo is moved, the body has just finished egg retrieval and stimulation, the physical condition is not good, and the body of the frozen embryo has almost recovered.

The frozen embryo is good, and the body is restored at that time, and it is easier to implant. However, it is necessary to consider the embryo thawing rate in the hospital, otherwise they will be thawed and died, let alone transferred.

Fresh embryo or frozen embryo transfer, in fact, there is no good or bad between these two methods. Whichever method you choose, after the egg is retrieved, the woman's uterus must be examined again to confirm whether it is a fresh embryo or a frozen embryo transfer. It is recommended that you go to a regular hospital for IVF technology.

The success rate of frozen embryos is higher than that of fresh embryos.

Frozen embryo transfer is a method in assisted reproductive technology in which fertilized eggs are cultured to the blastocyst stage and then cryopreserved, and then thawed and transferred at the appropriate time. Frozen embryo transfer can better control the patient's endometrial state and embryonic development, and improve the success rate of transfer.

The application range of frozen embryos:

1. Patients who have failed multiple IVF: Frozen embryo transfer can provide better opportunities for patients who have failed multiple IVF times and increase the success rate of pregnancy.

2. Older patients: As women get older, the quality of eggs gradually declines, and frozen embryo transfer can provide better quality embryos for older patients.

3. Patients with abnormal menstrual cycles: such as patients with irregular menstrual cycles or other endocrine abnormalities, frozen embryo transfer can better control the endometrial state and improve the success rate of transplantation.

4. High-risk patients: Frozen embryo transfer can reduce the risk of multiple pregnancies, especially for patients with a history of high-risk pregnancies. <>

Look at the quality of the embryo, if the quality is the same, the fresh embryo is still higher, the current Thai technology is more advanced, the success rate of fresh embryo and frozen embryo is about the same.

American American pregnancy, the success rate of embryo sacs is high!

All are similar, fresh embryos have not undergone the process of freezing, resuscitation, etc., and the activity is high, but the mother may affect the intrauterine environment due to the influence of a series of drugs such as stimulation and egg retrieval, and then affect implantation.

The difference between frozen embryos and fresh embryos1. Fresh embryos are embryos cultured in several sheds of petri dishes, which are still in the fresh stage. It has not undergone any treatment.

Frozen embryos are frozen with liquid nitrogen, that is, the metabolism of the embryos is suspended. Wait until the time you need a transplant to thaw the transplant;

2. After the frozen embryo is thawed, it is actually as fresh as the fresh embryo, without any difference. At least judging from current scientific research and practice, there is no difference.

Why freeze embryosThis is due to two considerations:

On the one hand, it can be used for a superovulation cycle to obtain a large number of embryos, ***, and cannot be transferred all at once, so the remaining frozen embryos are preserved.

On the other hand, many patients have severe ovarian hyperactivity, and it is not suitable to transfer embryos in the ** cycle, and the embryos can be frozen. After the body is well adjusted, the transplant will be chosen.

Which has a higher success rate, frozen embryo or fresh embryo1. From the perspective of the embryo. Frozen embryos are no different from fresh embryos. After the embryo is frozen, there is no problem as long as it survives and continues to develop after thawing.

However, frozen embryos will only be damaged during the thawing process, and embryos damaged by thawing cannot be transferred, so the fetus will not be affected in any way.

2. From the patient's point of view. Some female friends will have temporary endocrine disruptions for a short period of time after ovulation induction, which will not only cause the woman's uterus to not synchronize with the development of the embryo, which will affect the success rate of IVF. Frozen embryo transfer can be done after the drug reaction disappears, and even slowly wait for the woman's body to adjust before doing embryo transfer, and in this case, the success rate of frozen embryo transfer is relatively high.

So there is no difference between the two, and the doctor will help you choose the plan that maximizes your benefits. Which is more suitable for you, you will choose.
