Work, marriage, and childbearing do not always follow the same timeline. Some people do not currently have plans to have children, some want to complete their education and career first, and others delay having children because of their partner or reproductive plans. At the same time, female fertility gradually changes with age. For this reason, more and more people are beginning to consider an important question: If I am not ready to have children now, can I preserve my future reproductive options in advance?

 

What Does Egg Freezing Preserve?

 

Egg freezing does not preserve a “young state,” but rather the mature oocytes obtained at the time of egg retrieval. As women age, ovarian reserve gradually declines, and egg quality may also change. Therefore, the significance of egg freezing is primarily to preserve eggs from a particular stage as much as possible and provide an additional option for future reproduction.

 

Vitrification is currently the main clinical technology used for egg freezing. Compared with traditional slow freezing, vitrification rapidly lowers the temperature of the eggs and reduces cellular damage caused by ice crystal formation, making it an important technology for the cryopreservation of mature oocytes.

 

What Steps Are Typically Involved in Egg Freezing?

 

Before egg freezing, an assessment of ovarian function and overall physical health is required. Based on the examination results, an ovarian stimulation plan is then developed. Medications are used to promote the development of multiple follicles, while ultrasound and hormone testing are used to continuously monitor follicular changes.

 

Once the follicles reach an appropriate stage of development, egg retrieval is performed. After mature eggs are obtained, they are frozen for storage. The entire process usually involves one ovarian stimulation cycle, while the specific duration and medication plan may vary depending on the individual.

 

When these eggs are needed in the future, they still need to undergo thawing, fertilization, and embryo culture. After thawing, the eggs are usually fertilized through intracytoplasmic sperm injection, and the resulting embryos are cultured until the blastocyst stage.

 

Why Does IVF-PGT Come Into the Picture After Egg Freezing?

 

Egg freezing is only the first half of fertility planning. If frozen eggs are used for IVF in the future, the process will still involve fertilization, embryo culture, and embryo transfer.

 

Once embryos develop to the blastocyst stage, PGT testing can be performed to analyze the embryos’ chromosomes and relevant genetic information. For people planning to undergo IVF-PGT, IVF-PGT is an important technical step to focus on during the embryo stage.
