With the development of society and the change of concepts, women are also facing the reality that the childbearing age is gradually delayed while pursuing studies and careers. Women's ovarian function begins to decline from around the age of 30, and follicular reserve declines rapidly after the age of 35.
Under such circumstances, oocyte cryopreservation technology, also known as “cryogenic egg freezing”, has become increasingly popular among women as a form of assisted reproduction. It is seen as a special kind of “reproductive insurance”.
Currently, in my country, the application of egg freezing technology faces strict policy restrictions.
,.According to the "Technical Specifications for Human Assisted Reproduction" promulgated by the former National Health and Family Planning Commission in 2003, it is clearly stipulated that "it is prohibited to implement human assisted reproductive technology for couples and single women who do not comply with the provisions of national population and family planning laws and regulations."This means that currently, egg freezing technology is only allowed in China for married couples who meet the family planning policy and if there are specific medical indications (such as having tumors that require radiotherapy or chemotherapy and other diseases that may damage reproductive function).Healthy single women are not yet able to legally freeze eggs in the country for the purpose of delaying childbearing.
,.This is mainly due to the fact that egg cells are more vulnerable to damage during cryopreservation and recovery. At the same time, ovulation promotion and oocyte retrieval operations themselves also have certain risks, such as ovarian hyperstimulation syndrome (OHSS), which may be manifested as ovarian enlargement, ascites, abdominal pain, etc. There are also risks of bleeding and infection during oocyte retrieval, although the incidence is low.
Given the domestic policy environment and technical considerations, some women who have the need for frozen eggs may consider seeking out countries and regions with more relaxed policies abroad.
Many states in the United States allow single women to legally freeze their eggs. The technology is advanced but the cost is relatively high.
USSeveral states allow single women to legally freeze their eggs. This technology is quite advanced, but the costs are relatively high.
CanadaSingle women are allowed to freeze their eggs, and they have access to a comprehensive medical care system and advanced technology.
Thailand,,.
JapanHealthy single women can apply for egg freezing (it is generally not recommended for women over 40). Some local governments even offer subsidies for this service.
Russia,.
CambodiaThe relatively relaxed policies have attracted many international customers.
otherCountries like the UK, Georgia, Kazakhstan, and Kyrgyzstan have also begun to offer or introduce services related to frozen eggs.
When choosing a country for egg freezing, it is necessary to consider various factors such as the laws and policies of the destination country, the level of hospitals and laboratories, the professional qualifications of doctors, pricing, and the distance from home.
Female fertility is closely related to age.
.Data show that women's fertility rate will drop from about 80% in 20-29 years old to 63% after the age of 30, to 52% in 35-38 years old, to 36% in 40-44 years old, and only 5% after the age of 45.
Unlike men, the number and quality of eggs in women decline irreversibly as they age. This fact has prompted many women who are concerned about their reproductive plans to consider egg freezing as a option.
Especially for women who have received a high level of education, are single, and are between 35 and 40 years old, egg freezing becomes an important consideration.
III. What is egg freezing technology?
()(,-196℃).When needed, the frozen eggs are thawed and resuscitated, and used in vitro fertilization-embryo transfer technology to solve fertility problems.
This technology is not only applicable to healthy women who are temporarily unable to plan a family due to reasons such as academic or career development, but it can also help preserve the reproductive ability of women who may lose their fertility due to medical treatments, such as chemotherapy for cancer patients, which can impair fertility.
Egg freezing technology continues to improve.
.For example, the new generation DMSO-free egg freezing technology system aims to reduce the epigenetic risks that may be brought by traditional cryoprotectants and strives to more safely and efficiently preserve the development potential of eggs of all ages. Vitrification freezing technology effectively avoids the formation of ice crystals and greatly improves the survival rate of eggs by cooling down rapidly.
Currently in my country, according to regulations, egg freezing technology belongs to the category of human assisted reproductive technology, and its application has specific conditions.
,,,.However, in recent years, deputies to the National People's Congress and members of the Chinese People's Political Consultative Conference have suggested establishing and improving relevant laws, regulations and regulatory mechanisms at the national level, and piloting the opening of oocyte cryopreservation services for healthy married or unmarried women in central cities to fully respect women's fertility rights and respond to demographic challenges.
In addition, the scope of assisted reproductive technologies covered by medical insurance is gradually expanding. Several provinces have already included assisted reproduction procedures in their medical insurance coverage, which helps to reduce the economic burden on relevant families.
Egg freezing technology provides modern women with the possibility of delaying the birth clock, but it is not a complete "insurance".
,“”.Behind this, rational planning and economic investment are needed.
,,,.Research from the United Kingdom shows that 93.9% of women said they chose to freeze eggs because they were worried that the fertility rate would decline with age and prepare for future marriage and childbearing.
This is closely related to the global trend of increasing average marriage and childbearing ages.
,.Although the technology itself is constantly developing and improving, and its application needs to be carried out within existing policy frameworks, it does open a window of hope for women who need to postpone childbearing for various reasons.Modern women who are looking for a balance between career and childbirth can better plan their life paths by keeping an eye on technological development and understanding relevant policy trends.
