Understanding Egg Vitrification
Egg vitrification is a modern freezing technique that minimizes the formation of ice crystals, which can damage cells. This process involves freezing the eggs at -196°C, effectively halting their biological clock and preserving their age and quality until they are ready to be used. This method is widely used for social freezing, donor eggs, and infertility preservation for future use.
The Process and Impact of Egg Vitrification
During the vitrification process, eggs are prepared using a method called denudation, which involves removing the cells surrounding the egg and preparing it for freezing or fertilization through Intracytoplasmic Sperm Injection (ICSI). It is important to note that once the eggs are vitrified, natural fertilization becomes more challenging due to the removal of surrounding cells, and they must be fertilized using ICSI.
Comparing Fresh and Frozen Eggs
1. Infertility Outcomes: Recent advancements in freezing technology have significantly reduced the differences in infertility outcomes between fresh and frozen eggs. Research and clinical results at our clinic indicate that the fertilization rates, embryo development, and pregnancy rates from both fresh and frozen eggs are comparable.
2. Egg Viability and Selection: One of the key differences lies in the selection process. Fresh eggs are typically selected and used immediately after retrieval, ensuring the highest quality eggs are chosen. In contrast, frozen eggs often include eggs that were not selected for immediate use or are from high-yield donor cycles, containing a mix of varying qualities.
3. Blastocyst Development: There is little difference in the blastocyst development rate between fresh and frozen eggs. Fresh eggs avoid the stresses associated with freezing and thawing, which may minimally impact their developmental potential.
4. Logistical and Emotional Considerations: Using fresh eggs requires synchronization of cycles between the donor and recipient, which can be more complex and emotionally challenging. Frozen eggs offer greater convenience, as they are immediately available and can be planned around the recipient’s schedule.
The Role of Sperm in Infertility Treatments
While focus often centers on the egg, sperm selection is equally important. The use of fresh oocytes with cryopreserved sperm is a common practice, balancing egg quality with logistical convenience. Cryopreserved sperm generally offers a wide range of choices and is readily available without compromising treatment outcomes, unlike the delicate balance required with frozen eggs.
