The traditional IVF process mainly includes ovarian stimulation, egg retrieval, fertilization, embryo culture, and transfer. As embryo laboratory technology continues to develop, modern assisted reproduction has placed greater emphasis on embryo assessment at the blastocyst stage.

 

After fertilization, embryos undergo continuous cell division and continue to be cultured until they reach the blastocyst stage. Not all fertilized eggs can successfully develop into blastocysts, and this process itself involves natural selection.

 

After blastocyst formation, IVF-PGT, also known as IVF-PGT embryo genetic testing, can be used to further analyze the chromosomal status of embryos, providing more detailed information for subsequent embryo selection and transfer. For families seeking more precise fertility planning, IVF-PGT has become an important part of understanding modern assisted reproductive technology.

 

Why Is It More Important to Pay Attention to Embryos as Age Increases?

 

Female age is closely related to ovarian reserve and egg quality. As age increases, the number of eggs retrieved may change, and the likelihood of chromosomal abnormalities in embryos formed from eggs may also increase.

 

Even when the number of eggs retrieved in one cycle is relatively low, it does not necessarily mean that it will be impossible to obtain transferable embryos. If suitable mature eggs can be obtained and successfully develop into blastocysts, subsequent embryo assessment remains equally important.

 

The United States established a relatively mature assisted reproductive medical system at an early stage and has accumulated extensive experience in reproductive centers, embryo laboratories, and embryo genetic testing. For those considering U.S. IVF or U.S. egg freezing, in addition to paying attention to doctors and medical institutions, it is also important to understand the laboratory’s embryo culture capabilities, blastocyst culture process, and IVF-PGT-related technology.

 

How Should Egg Freezing and IVF Be Planned in Advance?

 

For people who do not currently have plans to have children but want to preserve the possibility of future fertility, U.S., Mexico, and Japan egg freezing is also an option often considered as part of fertility planning. Egg freezing can preserve the egg resources available at the time of retrieval, but it cannot guarantee a pregnancy in the future. Egg survival after thawing, fertilization, embryo culture, and subsequent IVF-PGT testing may all affect the final outcome.

 

The team at IVF USA, founded by Dr. Nathan Zhang, has been engaged in overseas assisted reproductive consultation services for more than ten years, providing U.S. egg freezing, U.S. IVF, and third-party assisted reproductive services for those in need. With nearly 20 years of experience in the overseas assisted reproduction field, IVF USA entered the Mexican market early based on the diversification and personalization of reproductive needs and became the Chinese representative of Power Fertility Center, Mexico POWER Fertility Center (POWER IVF). Dr. Nathan Zhang’s services have now expanded beyond the United States to include IVF and egg freezing in Mexico, IVF and egg freezing in Japan and Thailand, as well as regions including Taiwan and Hong Kong.
