Why do IVF need more embryos?
In vitro baby transplantation is a method of inserting fertilized eggs into the mother's uterus through laboratory assisted technology to treat infertility. In the process of IVF transfer, multiple embryos are often needed for transfer. Why multiple embryos? The following aspects will elaborate on this.
Improve the success rate of IVF transplantation
In the process of IVF transfer, there is a correlation between the number of embryos transferred and the success rate. Since the implantation success rate of each embryo is not 100%, transplanting multiple embryos can improve the success rate of IVF. In Monash IVF, a famous test tube baby center in Australia, research shows that the success rate of transferring two embryos is higher than that of transferring one embryo among older female test tube baby patients.
First, transplanting multiple embryos at a time can increase the chances of implantation. Simultaneous transfer of multiple embryos can improve the probability of implantation of at least one embryo, thus increasing the success rate of IVF transplantation.
Secondly, the transfer of multiple embryos can save time and cost. If only one embryo is transferred and the transfer fails, the patient needs to perform the IVF transfer process again. If multiple embryos are transferred at one time, the repetition of the transfer cycle can be reduced, and the economic burden and psychological pressure of patients can be reduced.
Finally, the transfer of multiple embryos can also increase the success window of IVF transfer. Different embryos may have deviation in implantation time. Transplanting multiple embryos can increase the success rate, because one embryo may be easier to be implanted at the right time.
Screening high-quality embryos
At the same time, in order to improve the success rate of IVF and reduce the risk of pregnancy and childbirth, the transfer of multiple embryos can also help to screen high-quality embryos.
By transplanting multiple embryos, doctors can observe and evaluate the development and quality of each embryo. Among the well developed embryos, selecting the best embryo for transplantation can increase the success rate of IVF.
In addition, by observing the development of embryos, doctors can screen out embryos with potential genetic diseases or chromosome abnormalities, thus avoiding the birth of babies with genetic problems.
Increase the chance of having multiple babies
Multiple embryo transfer can also increase the chance of multiple births, that is, twin or multiple pregnancies at the same time. This may be the expectation of some couples, and it can also increase the chance of a successful embryo transfer to give birth to a healthy baby.
However, Duobao at one birth also brings higher pregnancy and childbirth risks, such as premature delivery, low weight, etc. Therefore, multiple embryo transfer needs to be carefully balanced based on individual conditions and doctors' suggestions.
Provide more treatment options
Finally, multiple embryo transfer provides more treatment options for different patients. The success rate of IVF transplantation varies with age, patient's physical condition and infertility causes. Therefore, for some elderly patients or patients with unexplained infertility, multiple embryo transfer can increase the success rate and provide them with more treatment options.
In conclusion, IVF transplantation of multiple embryos can improve the success rate, provide better embryo screening opportunities, increase the chances of multiple births and provide more treatment options. However, each patient needs to consider individual conditions when deciding to transfer multiple embryos, and accept professional advice from doctors.
Summary
The reasons why IVF transfer needs multiple embryos can be explained from the following aspects: First, multiple embryo transfer can improve the success rate of IVF transfer; Secondly, the transfer of multiple embryos can help to screen high-quality embryos; Moreover, multiple embryo transfer can also increase the chance of having multiple babies; Finally, multiple embryo transfer provides more treatment options for different patients. By transplanting multiple embryos, the success rate of IVF can be improved and the expectations and needs of couples can be met at the same time. However, it is also necessary to pay attention to the risks of pregnancy and childbirth and make decisions under the guidance of doctors.
