In today’s continuous development of IVF technology, the United States has attracted the attention of many couples with its outstanding success rate in IVF. Blastocyst culture, as a crucial step in the IVF process, involves the continued cultivation of embryos from the early stages until they reach the blastocyst stage. The success rate at this stage directly affects the pregnancy rate after transplantation. Many people want to know, when going to the United States for IVF, how high is the success rate of blastocyst culture?

Compared to the average success rates in other countries or regions, the success rate of blastocyst culture in the United States can be over 90%, a number that undoubtedly stands out. However, more importantly, the success rate of blastocyst culture in American IVF is not just a number but a powerful guarantee for many families to realize their dreams of reproduction. The reason the United States can achieve such a high success rate in blastocyst culture is mainly attributed to its advanced laboratory equipment, professional medical teams, and meticulous operational procedures. From the selection of early embryos to the cultivation conditions during blastocyst culture, each step undergoes careful design and strict control. In addition, the rich experience and professional knowledge of doctors are also crucial factors in the success of blastocyst culture.

Key factors for the high success rate of blastocyst culture in American IVF:

1. Advanced laboratory equipment

The laboratory environment and conditions are crucial for the growth of embryos, and a professional laboratory environment can provide suitable conditions for embryo growth. If the created in vitro culture environment cannot meet the growth needs of embryos, the vitality of embryos may decrease, or they may die. The laboratory at American fertility centers is equipped with spindle observation systems, micro-manipulation instruments, laser membrane rupture devices, blastocyst incubators, pH meters, ICSI (Intracytoplasmic Sperm Injection) devices, CO2 incubators, Coda Air air purification systems, and incubators for blastocyst culture. The incubator used for blastocyst culture simulates the human uterine environment, allowing embryos to grow and develop in an environment that is light-free, sterile, dust-free, temperature and pressure-controlled, humidified, and with carbon dioxide and oxygen concentrations similar to the intrauterine environment, ensuring the safety of embryos and allowing them to develop smoothly into the blastocyst stage.

2. Professional medical teams

During the blastocyst culture process, doctors provide a suitable development environment for fertilized eggs through highly specialized laboratory equipment and meticulous operational procedures. American fertility centers have internationally recognized experts in IVF, each with over 25 years of experience in the field. Some experienced experts can reasonably control the nutritional components, energy substances, osmotic pressure, acidity, and alkalinity in the embryonic nutrient solution based on the development of embryos, with minimal impact on embryo activity. The composition of the culture medium is crucial, and various indicators must be consistent with the growth environment in the mother’s body to ensure the smooth growth and development of embryos. American IVF experts use precise timing control and liquid regulation technology to develop the required culture medium, maintaining the fertilized eggs in an ideal state of growth.

3. Meticulous operational procedures

The development of blastocysts generally takes 5 days. On the first day, fertilized eggs divide into 2 cells, on the second day into 4-6 cells, on the third day into 6-8 cells, on the fourth day into mulberry embryos with 16-32 cells, until the fifth day when they divide into more than 100 cells, forming blastocysts. At this stage, embryos have better developmental potential and greater tolerance. This process is an extremely precise and high-end medical technology, requiring extremely meticulous operation. Throughout the cultivation process, American IVF experts strictly control the use of blastocyst incubators, the amount and replacement of culture medium, embryo development, and time monitoring to avoid accidents that could lead to the failure of blastocyst culture.
