Older women often face the challenge of miscarriage during pregnancy, primarily due to embryo quality. This viewpoint has been thoroughly validated in the practice of IVF. The quality of embryos first depends on the health of the maternal reproductive cells. If the eggs are mature, healthy, and free from diseases, the chances of successful pregnancy significantly increase.
Another critical factor in embryo quality is the normality of chromosomes. As women age, the likelihood of chromosomal abnormalities gradually increases. During fetal development, the number of maternal cells peaks and then decreases year by year. Over time, these cells are affected by factors such as body and environmental pollution, radiation, harmful viruses, and others, increasing the risk of chromosomal abnormalities. The embryologists at IVF USA promptly halt the development of embryos found to have chromosomal abnormalities to ensure that only healthy embryos are implanted. Daily assessments of embryo quality are conducted to prevent such complications, sometimes even several times a day.
In the process of in vitro fertilization, the qualifications of reproductive center staff and laboratory testing equipment also influence embryo quality. Embryos in developmental stages are highly sensitive to any changes; even the slightest disruption can halt their development. Therefore, only healthy embryos significantly increase the chances of successful pregnancy.
To better distinguish embryo quality, embryologists classify embryos. It is extremely rare for all embryos to develop normally throughout the entire incubation period, so doctors need to understand which embryos are viable and which are not. Typically, embryo inspection and classification occur on the day of embryo transfer, usually on the 5th day after fertilization. This is crucial information for determining embryo potential and identifying which embryos will attach and develop fully.
Statistics show that only high-quality and mature blastocysts can survive after freezing and continue to develop. With medical advancements, modern embryo monitoring methods are becoming more prevalent. Recently, technology for continuous monitoring using delayed microscopes has been introduced, allowing embryos to be evaluated for development and quality through automated photographing procedures without removing them from the incubator, thus reducing negative external influences on embryos.
