The Influence of Old Childbearing on the Intelligence Quotient of Boys
With the change of society and marriage concept, more and more women choose to conceive in their later years, that is, the so-called elderly childbearing. However, there has long been a dispute about the impact of elderly childbearing on children's IQ. This paper aims to explore the impact of elder childbearing on boys' IQ by analyzing relevant research and survey data.

1. Physiological factors of mother
The fertility of women will decline with the growth of age, and the elderly fertility may lead to a series of physiological problems, such as fetal gene abnormalities, placental dysfunction, etc. These problems may directly affect the brain development and IQ of the fetus. A study points out that the IQ of boys born to women over 35 is generally lower than that of boys born to mothers of the same age.
In addition, when pregnant at an advanced age, women's physical quality is generally relatively poor, and there may be more chronic diseases and malnutrition problems, which will also affect the growth and development of the fetus in the womb. Therefore, relevant studies have found that among boys born at an advanced age, it is more common for boys whose IQ is lower than that of boys born at a younger age.
In addition, the elderly childbirth may also increase the risk of premature delivery, and premature infants have higher intellectual development problems. The brain development of premature infants is not fully mature, and they are vulnerable to interference from the external environment, which will also have a negative impact on the IQ of boys.
2. Psychological factors of parents
Elderly childbearing is often accompanied by a long period of infertility treatment, and has experienced many failed pregnancy efforts, which has caused a certain impact on parents' psychological state. A study found that parents of older boys generally have higher levels of anxiety and depression. This psychological pressure may affect parents' educational methods and attention to their children, and thus affect boys' IQ.
In addition, older pregnancies often require more money, time and energy, which may also lead to a relative lack of resources for parents to educate their children. Therefore, boys born at an advanced age may face the shortage of educational resources, which will affect their IQ development.
3. Family environment factors
Families with older children tend to be in a higher socio-economic status, which means that children may have better living conditions and educational resources. However, at the same time, there are also problems of late parent-child relationship and low intimacy in the elderly childbearing families. A study found that older boys generally face difficulties in communicating with their parents and inharmonious parent-child relationships, which has a certain negative impact on the development of IQ.
In addition, children born at an advanced age may face a more closed and protectionist family environment, which will limit their social and learning opportunities, thus affecting the development of IQ.
4. Education environment factors
Boys born at an advanced age may be more vulnerable to excessive care and expectations. Parents who are older usually have higher expectations of their children, but too high expectations may bring too much pressure to boys, thus affecting the development of IQ.
In addition, compared with young parents, parents who give birth at an advanced age may not be familiar with modern education methods, which leads to their inability to provide boys with a good learning and growth environment. This will also have a certain negative impact on boys' IQ.
Summary
To sum up, the elderly childbearing has a certain impact on boys' IQ. This kind of influence mainly comes from mother's physiological factors, parents' psychological factors, family environment factors and educational environment factors. Although the impact of elderly childbearing is multifaceted, it does not mean that boys born at an older age will inevitably have low IQ, and it is also necessary to comprehensively consider the impact of family education and other environmental factors. Therefore, when choosing the childbearing age, parents should make rational decisions according to their own conditions and resources, so as to provide better conditions and environment for the development of children's IQ.
