Overview of elder childbearing
With the development of social economy and the improvement of people's living standards, more and more couples choose to postpone childbearing. Elderly childbearing refers to the childbearing of women over 35 years old or men over 40 years old. Although elder childbearing contributes to family stability and personal career development, it is also accompanied by a series of health risks and social problems. Therefore, countries have formulated relevant national laws and regulations to regulate the elderly childbearing behavior and protect the interests of couples and children.

1. Legal age limit
In order to ensure that elderly couples have the physical and psychological conditions suitable for healthy pregnancy and childbirth, many countries have set legal age limits. For example, in France, in view of the increased risk of pregnancy after the age of 40, the law stipulates that women over the age of 40 need to conduct a health assessment and obtain the consent of a doctor before using assisted reproductive technology. In addition, in Japan, women who have reached the age of 44 are no longer allowed to use artificial insemination technology. These legal age limits are designed to reduce the risk of childbirth at an advanced age and protect the health of pregnant women and fetuses.
However, these legal age limits have also caused some controversy. Some people believe that laws and regulations should be more flexible, and whether or not to give birth at an advanced age should be determined according to the individual's physical condition and fertility desire.
2. Review of assisted reproductive technology
Assisted reproductive technology is an important means for many elderly couples to achieve fertility. In order to ensure the safety of assisted reproductive technology and the legitimate rights and interests of elderly couples, national laws and regulations require that couples using assisted reproductive technology be reviewed. For example, Canada's Reproductive Medicine Act stipulates that all couples receiving artificial insemination, IVF and other technologies must undergo medical evaluation to ensure that they have the conditions for safe pregnancy and childbirth. Similarly, China's Administrative Measures on Human Assisted Reproductive Technology also requires physical and psychological assessment of couples.
These review systems are designed to reduce the risk of elderly childbearing, prevent couples who are not suitable for childbearing from using assisted reproductive technology, and avoid potential health problems and ethical dilemmas.
3. Medical and consulting support
The health risks faced by elderly childbearing are higher than those faced by young couples. Therefore, national laws and regulations require that medical and advisory support be provided to help elderly couples make wise childbearing decisions. For example, Australia's Assisted Reproductive Therapy Act stipulates that couples must receive counseling to understand the risks and consequences before accepting assisted reproductive technology.
In addition, some countries have established special fertility clinics or units for the elderly to provide all-round medical and advisory support for elderly couples through multidisciplinary collaboration. For example, Johns Hopkins Hospital in the United States has a fertility age extension clinic to provide personalized medical and psychological support for elderly couples.
4. Social security policy
The elderly childbearing not only has certain risks to individual couples, but also has certain impact on society. In order to solve the social problems caused by the elderly childbearing, some countries have formulated relevant social security policies. For example, Sweden has implemented a policy called "flexible welfare", which provides financial support and flexible working arrangements for couples who delay childbearing, so as to balance the needs of career and family. These social security policies aim to reduce the burden of elderly childbearing on couples and society.
Summary
Older childbearing is faced with different laws and policies in various countries. These regulations include legal age limit, assisted reproductive technology review, medical and counseling support, and social security policies. These regulations are aimed at protecting the interests of elderly couples and children and assisting them to achieve their reproductive aspirations under safe and healthy conditions. However, these regulations also need to be flexible, taking into account individual differences and fertility intentions, so as to provide more support and choices for elderly couples.
