Freezing Eggs in the USA: Not as Simple as It Seems?

2023-12-05 18:24:25,visits: 155

Whether you are prospective parents preparing for in vitro fertilization (IVF) or a single woman considering egg freezing, the process inevitably involves ovarian stimulation and egg retrieval. The primary distinction between freezing eggs and IVF lies in the waiting period for embryo transfer when freezing eggs, adding an extra step to the process.


Exploring the Egg Freezing Process


The technological principles behind egg freezing are not groundbreaking; it's akin to how we use refrigerators to freeze meat for future use. The focus here is on the survival of eggs after thawing.


In practice, freezing eggs is a technically demanding process, divided into three crucial steps: egg retrieval, freezing, and thawing. Each step requires meticulous attention to detail, as any oversight may jeopardize the efforts of prospective mothers.


Egg Retrieval


Before egg retrieval, the steps for freezing eggs and IVF are identicalinitial consultation, examinations, ovarian stimulation, and then egg retrieval. The entire process is relatively painless for patients, and if there are no complications, they can return home the next day.


Egg Freezing


Currently, American hospitals widely employ the vitrification freezing method. In simple terms, this process involves placing eggs in a high-concentration cryoprotectant solution to dehydrate them, followed by immediate storage in liquid nitrogen. This method effectively prevents ice crystal formation, preserving egg integrity during freezing.


After freezing eggs, when prospective mothers wish to conceive, the frozen eggs can be retrieved, thawed, and used for in vitro fertilization. This method achieves a 90% survival rate after thawing, an 80% hatching rate.


Thawing Process (Resuscitation)


Resuscitating eggs is essentially the reverse of the freezing process. The dehydrated eggs are rehydrated, and then doctors cultivate them in an environment simulating the human body. Eventually, these resuscitated eggs feel like they are back in a familiar environment, ready for a "full-blooded revival."


Can You Really Conceive Whenever After Freezing Eggs?


Certainly not! Women's ovarian function declines with age, leading to a decrease in both the quantity and quality of eggs. By the age of 38, the natural pregnancy rate is already quite low, and after 44, the success rate for natural pregnancy is almost zero.


So, for those considering IVF or egg freezing, remember: while you can catch up on work, reproductive capability is irreversible. In summary: Act on IVF early!
