What is the specific process for freezing eggs in domestic hospitals? The process of freezing eggs involves using drugs to promote egg excretion, taking dozens of eggs at a time, and then preserving the eggs for freezing. Take it out when needed. Frozen eggs are stored in liquid nitrogen at -196 ℃ for many years. In theory, no matter how many years, as long as thawing is successful, it can be as fresh as an egg.

It is best to consult a reputable hospital for frozen eggs, as frozen eggs have certain conditions. If unmarried and married women can conceive normally, they cannot freeze their eggs. For frozen eggs in China, only women who meet the requirements for assisted reproduction can have frozen eggs, and normal women with a need for frozen eggs can consider going abroad. The following is the process of freezing eggs:

1. Consultation and examination: Before freezing eggs in China, relevant examinations need to be conducted to see if they meet the conditions for freezing eggs. For example, women with malignant tumors can freeze their eggs before receiving high-dose chemotherapy, while foreign countries generally allow normal women to freeze their eggs

2. Excreting eggs: The process of freezing eggs can be officially initiated when conditions are met. The first step is to use ovulation promoting drugs to advance the development of multiple follicles, and then use puncture techniques to obtain dozens of eggs.

3. Egg preservation: After removing the egg, it is the most critical preservation process. Firstly, pre-treatment should be carried out in a cryoprotectant to fully dehydrate the egg, and then the egg should be vitrified using ultra high speed technology.

Frozen egg

There are two common freezing methods:

1. Programmed freezing, which means gradually cooling and freezing according to the set program, and finally storing in liquid nitrogen.

2. Rapid vitrification and freezing, after pre-treatment of eggs in cryoprotectants, they are directly stored in liquid nitrogen frozen at -196 ℃ at an extremely fast rate.

Vitrification freezing does not cause significant damage to eggs, so this method is currently mainly used.

Which women are suitable for 'frozen egg' technology?

Considering the safety of frozen eggs, domestic policies prohibit single women from undergoing assisted reproductive technology related surgeries. When applying for frozen egg technology, three documents must be provided: ID card, marriage certificate, and birth certificate.

Cancer patients hope to preserve fertility by freezing their eggs. Patients can have their eggs frozen for future testing before surgery and chemotherapy.

2. Women who suffer from infertility and require in vitro fertilization techniques can freeze their eggs, provided that the husband is temporarily unable to provide sperm or extract more eggs.

3. Women under the age of 35 who give birth after the age of 35 due to various considerations can have their eggs frozen before the age of 35 because freezing after the age of 35 is not significant. At this point, the nest reserve function of the egg has significantly decreased.

4. Women with premature aging caused by factors such as egg chromosomes, autoimmune diseases, infections, tumors, etc.

5. People with sexually transmitted diseases. Most sexually transmitted disease patients have pelvic inflammatory disease, which disrupts the function of female blood transfusion egg tubes and greatly reduces the activity of eggs.

What is the specific process for freezing eggs in domestic hospitals? The above is the specific process for freezing eggs in China. In China, the application of frozen egg technology is not widespread, mainly used for infertile women who need chemotherapy or radiation therapy due to certain diseases, which may affect the function of egg nest and lead to secondary infertility or fertility requirements. This is an inevitable way.
