1、 Physiological effects
The elderly childbearing has a certain impact on the physical health of both spouses. When women's reproductive age is delayed, their ovarian function will gradually decline, and the quality of their eggs will also gradually decline. This has led to the decline of ovulation function, egg quality and fertility. For men, the number and quality of sperm will gradually decline with age.

At the same time, the elderly childbearing may also increase the risk of pregnancy complications. For example, the incidence of gestational diabetes, gestational hypertension and other diseases will increase with age. These complications will bring certain risks to the health of pregnant women, and will also increase the difficulty of postpartum recovery.
In addition, the elderly birth will also increase the risk of fetal birth defects. The study found that the probability of women over 35 years old having Down syndrome in childbirth increased significantly. In addition, some other common fetal birth defects, such as incomplete neural tube closure, cleft lip and palate, are also related to the elderly childbearing.
2、 Psychological influence
The elderly childbearing has a certain impact on the mental health of both spouses. When choosing to give birth at an advanced age, the couple may face greater pressure and anxiety. They may worry about whether their physical condition can withstand the pressure of pregnancy and childbirth, or whether the fetus is healthy.
In addition, both spouses may feel tired and lost due to the longer time and more efforts required to give birth at an advanced age. When they try many times but fail to conceive successfully, they may feel depressed and remorse. These negative emotions may have a negative impact on the relationship between husband and wife, increasing tension and contradictions between husband and wife.
In addition, elderly childbearing may also increase the sense of worry about the future. Couples may worry about whether their physical condition can keep up with the growth of their children, and whether their ability and energy in raising children are sufficient. These concerns may increase anxiety and insecurity between couples.
3、 Economic impact
Older childbearing will also have a certain impact on the economic status of couples. In the process of elderly childbearing, more prenatal examinations and post natal care are needed, which will increase the medical expenses. In addition, if the assistance of assisted reproductive technology, such as IVF, is needed, the cost of surgery and treatment will also increase accordingly.
At the same time, the elderly childbearing may also increase the time and energy input of both spouses. Taking care of children and working at the same time may make couples feel tired and stressed. If they give up their jobs because of the need to raise children, the economic burden between the husband and wife may increase.
In addition, elderly childbearing may also affect the retirement plans of couples. If the couple gives birth at a later age and the child is still under age, the couple may still need to continue working to ensure the economic stability of the family, and cannot enjoy retirement as planned.
4、 Family relationship impact
The elderly childbearing will also have a certain impact on the family relationship between husband and wife. Both husband and wife need to fully communicate and negotiate the decision on fertility, and at the same time, they need to support and encourage each other. If there are differences or poor communication between the two sides on the attitude of fertility, it may lead to contradictions and conflicts.
In addition, elderly childbearing may cause changes in the focus and role of husband and wife families. After welcoming the arrival of the new life, the husband and wife need to adjust the division of roles and the operation of the family. This may cause tension and maladjustment among family members.
However, the elderly childbearing may also deepen the intimate relationship between husband and wife. After the arduous birth process, the husband and wife may cherish each other more and strengthen their dependence and support. They may care more about each other and face the challenge of raising children together.
Summary
The influence of elderly childbearing on the relationship between husband and wife is multifaceted. In terms of physiology, childbirth at an advanced age may increase the risk of pregnant women and fetuses, and affect the health of both spouses. In terms of psychology, the elderly childbearing may lead to the stress and anxiety of both spouses, and affect the emotion and interaction between couples. In terms of economy, elderly childbearing will increase medical expenses and child rearing costs, which will have an impact on the economic status of couples. In terms of family relations, elderly childbearing may cause changes in the roles of both husband and wife and family focus, and affect the relationship between family members. In general, elderly childbearing requires both spouses to be fully prepared psychologically and economically, and to support and understand each other in the process of childbearing, so as to better cope with the impact of elderly childbearing.
