How to choose test tube baby frozen embryos or blastocysts?
As an assisted reproductive technology, in vitro fertilization (IVF) has helped many infertile couples realize their dreams. In the process of IVF, frozen embryos and blastocysts are two common ways of embryo selection. For couples who intend to obtain a baby through IVF, how to choose frozen embryos or blastocysts will be an important decision. This article will elaborate on how to make a choice from four aspects: embryo quality, women's age, treatment course and doctor's advice.
Embryo quality
Frozen embryos and blastocysts are both embryos developed after in vitro fertilization, but their development stages are slightly different. Frozen embryos are formed 3 to 5 days after fertilization, while blastocysts are formed 5 to 6 days after fertilization. Generally speaking, blastocysts are relatively more developed and have a higher implantation success rate. Therefore, when selecting embryos, we can give priority to blastocysts.
In addition, embryo quality is also an important indicator. High quality embryos often have higher implantation success rate and lower abortion risk. Through the embryo quality assessment, we can understand the cell division, embryo number, chromosome abnormalities and other information of the embryo. Generally speaking, high-quality embryos should be given priority when selecting embryos.
When selecting frozen embryos and blastocysts, you can refer to the embryo evaluation report of the hospital, and select suitable embryos through discussion with the doctor.
Age of women
Women's age is an important factor affecting the success rate of IVF. With the growth of age, the number and quality of female eggs will gradually decline, thus affecting the quality of fertilized eggs and the survival rate of embryos. Generally speaking, the quality of eggs produced by young women is better, and the development of embryos is also better.
For young women, the choice of frozen embryos or blastocysts may depend on their personal circumstances and doctor's advice. If the quality of women's eggs is good, frozen embryos can be considered, because the development stage of frozen embryos is relatively early, with a higher success rate of implantation. However, if women's eggs are small in number or poor in quality, it may be recommended to choose blastocysts, because blastocysts are relatively more fully developed and have a greater chance of successful implantation.
Treatment course
Individual treatment course can also be considered when choosing frozen embryo or blastocyst. During IVF treatment, multiple egg retrieval and embryo culture may be required. If the individual's treatment course is relatively long, there may be more fertilized eggs to choose from. At this time, you can consider choosing frozen embryos because there are more frozen embryos.
On the other hand, if the individual's treatment course is relatively short, only a small number of fertilized eggs may be available. In this case, priority can be given to the selection of blastocysts, because blastocysts have better development and have a greater chance of successful implantation.
Doctor's advice
It is better to discuss with the doctor and listen to the doctor's advice on whether to choose frozen embryos or blastocysts. Doctors can give more targeted suggestions according to the specific conditions of patients and embryonic development.
The situation of each patient is unique, and the final choice of frozen embryo or blastocyst should be a comprehensive consideration. In the decision-making process, you can refer to your own women's age, personal health status, treatment course and other factors, and fully communicate and discuss with the doctor to finally select your own embryos. In this way, we can improve the probability of success of IVF and realize healthy baby dreams.
Summary
When selecting frozen embryos or blastocysts of test tube babies, comprehensive consideration can be given to four aspects: embryo quality, women's age, treatment course and doctor's advice. The patients with good embryo quality, young women and long treatment history can give priority to frozen embryos; The patients with poor embryo quality, older women and shorter treatment course can give priority to blastocysts. The final choice should be a decision based on full communication and discussion with the doctor and personal circumstances.
