What is the age of childbearing
To determine what age is considered to be the oldest child, multiple factors need to be considered, including fertility, pregnancy and childbirth risks, baby development issues, etc. The following is a detailed description of senior childbearing from four aspects.

Decreased fertility
As women grow older, their ovarian function will gradually weaken, and both the quality and quantity of eggs will decrease, leading to a decline in fertility. Generally speaking, the quality of eggs begins to decline when women reach the age of 35. With the increase of age, the rate of quality decline will accelerate. Among women over 40, the probability of successful pregnancy will be significantly reduced.
In addition, the quality and quantity of male sperm will also decrease with age, thus affecting the success rate of pregnancy. Therefore, age is an important consideration for both women and men.
Increased risk of pregnancy and childbirth
One of the important problems of elder childbearing is the increased risk of pregnancy and childbirth. After the age of 35, women will have a significantly increased risk of various pregnancy complications, such as gestational diabetes, pregnancy induced hypertension, pre eclampsia, etc. These diseases not only have an impact on the health of pregnant women, but also may have adverse effects on the fetus.
In addition, older pregnant women are more likely to have fetuses with chromosomal abnormalities. For example, 35 year old women have twice the risk of fetal chromosomal abnormalities as 30 year old women, and women over 40 have a higher risk. These chromosomal abnormalities may lead to genetic diseases such as Down syndrome at birth.
Therefore, it is necessary to take into account the increased risk of pregnancy and childbirth when giving birth at an advanced age, and carry out strict monitoring and management under the guidance of doctors.
Baby development problems
Babies born at an advanced age may also face some developmental problems after birth. The study found that babies born to elderly mothers are more likely to suffer from congenital heart disease, cleft lip and palate and other deformities. At the same time, the intellectual development of these babies may also be affected, and they are more prone to learning and cognitive problems.
However, although the babies of elderly mothers face these potential risks, there are also many examples of healthy babies born by elderly mothers. By means of prenatal examination, health management and treatment, the risk of baby development problems can be effectively reduced.
Hospital recommendations
Many hospitals have provided relevant suggestions for the situation of elderly childbearing. For example, the Department of Obstetrics and Gynecology of Peking Union Medical College Hospital suggested that when women over 35 years old are preparing for pregnancy, they should go to the hospital for a comprehensive examination to assess fertility and pregnancy risks. The doctor will give specific suggestions according to the individual situation, such as appropriate adjustment of lifestyle, assisted reproductive technology, etc.
In addition, doctors also stressed that we should pay attention to adjusting our mentality and maintain a positive and optimistic attitude when giving birth at an advanced age. Under the guidance of doctors, scientific pregnancy preparation and comprehensive management can improve the success rate of elderly childbearing and reduce the risk of pregnancy and childbirth.
Summary
To sum up, elder childbearing refers to the pregnancy of women over 35 years old. With the increase of age, the fertility will decline, the risk of pregnancy and childbirth will increase, and the baby's development may also be affected. The doctor suggested that women over 35 years old should go to the hospital for evaluation and guidance when preparing for pregnancy, so as to improve the fertility success rate and reduce the risk.
