Egg freezing
Egg Freezing
Egg freezing is a process of preserving female fertility. The female's eggs are taken out and treated with special cryoprotectants and freezing techniques, and then stored in a liquid nitrogen environment at -196°C, which stops the metabolism and molecular movement of the eggs and puts them in a long-term dormant state. They can be revived when needed and used in subsequent assisted reproductive processes.
Why do you need to freeze your eggs?
Women's fertility gradually declines with age, especially after the age of 35, when the quality and quantity of eggs will decrease significantly. By freezing eggs, women can preserve high-quality eggs when they are young and use them when they are ready to have children, thereby increasing the chances of pregnancy and the quality of fertility.
Who is suitable for egg freezing?
- Those who are not ready to have children for the time being due to age and other factors: Those who are not ready to get pregnant at the moment, especially women over 35 years old, can preserve their fertility by freezing their eggs.
- Disease treatment affects fertility: · Patients undergoing chemotherapy or radiotherapy: Patients undergoing chemotherapy or radiotherapy will have an impact on the quantity and quality of egg cells. Eggs can be frozen before treatment.
- Genetic disease patients: People with genetic diseases that cause rapid deterioration of the ovaries, such as Turner syndrome and fragile X syndrome.
- Patients who need ovarian surgery: Patients who need ovarian surgery, such as ovarian cysts (including chocolate cysts) and ovarian tumors.
- Those with special assisted reproductive situations: women whose husbands are unable to ejaculate after IVF treatment, have no sperm in their semen, or have insufficient sperm to complete fertilization.
- Those who plan to have children later: People who have no plans to have children at present but have the desire to have children, and plan to marry and have children later due to education, career and other factors. Social egg freezing can be an option for future family planning.
Preparation
The doctor will make an appointment to assess if you are ready to start taking ovulation medication. Ultrasound and blood tests
Start daily injections of ovulation medication. It usually takes 8-12 days, depending on each person's body response.
After the injection, the doctor will schedule 3-4 follow-up visits to evaluate the response and adjust the medication through ultrasound and blood tests. The doctor will schedule an egg retrieval when the eggs are the right size.
At what age should you freeze and store your eggs?
It can be done between the ages of 22 and 35, which allows for the production of a large number of high-quality eggs. As you age, the success rate of fertility from frozen eggs decreases due to the number and quality of eggs.
Will a child born from frozen eggs have any abnormalities?
Currently, a large amount of research and clinical data show that there is no significant difference in physical development, intelligence level, etc. between children born using frozen eggs and those born from natural conception.
How long can it be frozen?
With the support of current advanced assisted reproductive technology, frozen eggs can be safely frozen for up to 10 years if they comply with regulations and are under suitable conditions.
How are frozen eggs used?
After the frozen eggs are thawed in a specific solution, they are fertilized with sperm. After that, they undergo a series of delicate and orderly embryonic cultivation processes to gradually develop to the embryo stage suitable for transplantation back into the uterus, thereby achieving pregnancy.
