With the continuous advancements in IVF technology, more and more people are becoming interested, particularly in the processes involving the freezing of eggs, sperm, and embryos. As these advanced technologies become more accessible, many patients are beginning to question and focus on one crucial issue: Do the quality of frozen eggs, sperm, or embryos change over time? How long can these seeds of life be preserved?

 

Freezing technology has gradually matured with advancements in low-temperature biology. In recent years, the procedures have become simpler and more efficient. Particularly, the application of "vitrification" has led to even more ideal preservation results. This technology is now widely adopted by fertility clinics around the world and has become an essential aspect of assisted reproduction.

 

During the egg freezing process, healthy and mature eggs are retrieved from a woman's body using scientific stimulation methods and painless egg retrieval techniques. These eggs are then placed in a high-concentration protective solution and rapidly stored in liquid nitrogen at -196°C. At this temperature, the eggs enter a state akin to "hibernation," with time effectively standing still, preserving more options for future fertility plans.

 

Sperm freezing is also a reliable technique. When sperm is frozen with added protective agents, its biological activity is completely halted, meaning the quality of the sperm does not change over time. This freezing process provides a strong guarantee for many men needing to preserve their fertility.

 

Regarding embryo freezing, it typically occurs on the third or fifth day after fertilization. Especially for blastocysts formed on the fifth day, these are frozen only after rigorous morphological assessment and third-generation IVF-PGT screening. These high-quality embryos are stored in liquid nitrogen at -196°C, maintaining their original healthy state without further development or aging. Thus, it is not uncommon to see a mother who is 26 years old having a "27-year-old" frozen embryo for her child, a situation that seems perfectly reasonable under scientific and technological support.

 

However, the success of freezing technology largely depends on whether the medical institution implementing it has advanced equipment and technical expertise. Only through precise operations and scientific management can one ensure that frozen eggs, sperm, or embryos retain high quality and good viability after thawing. Therefore, choosing a medical institution with rich experience and excellent technology is particularly important.
