Whether having children over 35 years old affects intellectual development
With the development of modern society, more and more women choose to postpone childbearing. However, for women over 35 years old, whether having children will affect their children's intellectual development is a controversial topic. This paper will analyze this problem from the perspectives of biology, psychology, medicine and society.

Biological factor: egg quality
Research shows that the number and quality of female eggs will decline with age. Women over 35 years old have a higher risk of chromosomal abnormalities in their eggs, which may lead to genetic diseases. These chromosomal abnormalities may have a negative impact on children's intellectual development.
In addition, the aging of female eggs will also affect the development of embryos. The decline in egg quality of women over 35 years of age may lead to poor embryonic development, thus affecting the intellectual development of their children. However, it should be pointed out that not every child born to a woman over 35 will have intellectual problems, which depends on individual differences and genetic factors.
Psychological factors: family stability and parent-child relationship
Women over 35 years old may have a more mature and stable family and professional life. This kind of family stability and the establishment of parent-child relationship will help children's intellectual development. Research shows that family environment has an important impact on children's intellectual development, including parent-child interaction, emotional support and intellectual stimulation.
As women over 35 are more likely to be in a stable family environment, children may be more likely to receive good education and care, thus promoting intellectual development. Therefore, although biological factors have certain risks, psychological factors have a positive impact on children's intellectual development.
Medical technology: pregnancy aid
Modern medical technology provides women over 35 years of age with a variety of assisted pregnancy methods, such as in vitro fertilization (IVF) and egg freezing. Through these methods, women can delay childbirth and reduce the risk of egg quality decline.
However, these medical techniques cannot eliminate the risk of egg quality decline. Even if successful pregnancy is achieved through in vitro fertilization and other methods, women over 35 years old still need to face chromosome abnormalities and embryonic development problems. Therefore, medical technology can provide opportunities for choice, but it cannot completely eliminate the impact of biological factors on intellectual development.
Social factors: education and environment
Women over the age of 35 tend to have a higher level of education and professional experience. They are more likely to create a good learning environment and provide high-quality educational resources to children. Research shows that high-quality education and good learning environment have a positive impact on intellectual development.
In addition, women over 35 tend to be more stable and mature in socio-economic status, cultural background and family values. These factors will also affect children's intellectual development. Therefore, social factors have an important impact on intellectual development, and can compensate for the impact of biological factors to a certain extent.
Summary
To sum up, having children over 35 years old has certain risks to intellectual development, mainly due to biological factors. The decline of female egg quality and the increased risk of chromosomal abnormalities may have a negative impact on children's intellectual development. However, psychological factors, medical technology and social factors can compensate for this effect to a certain extent. Family stability and parent-child relationship, high-quality education and good learning environment are all conducive to promoting children's intellectual development. Therefore, when deciding whether to postpone childbearing, individuals should consider multiple factors comprehensively and seek advice and suggestions from professional doctors.
