The age limit of male elderly childbearing
With the extension of human life span and the change of social concepts, the elderly male fertility is gradually receiving attention. So, how old are men? In the view generally accepted by the medical community, the age limit for men to give birth at an advanced age mainly depends on the following aspects:
1. Decreased reproductive system function
With the increase of age, the function of male reproductive system will gradually decline. The quantity and quality of sperm will be affected, including the decrease of sperm quantity and the increase of sperm with abnormal morphology. These changes may have a certain impact on the ability to conceive and the health of the fetus.
Research shows that the age at which male fertility begins to decline can be about 45 years old. After this age, the male's ability to conceive will gradually decrease, the risk of pregnancy will also increase, and the health risk of the child at birth will also increase.
However, it should be noted that the fertility of men declines relatively slowly. Generally speaking, men under 50 years old still have high fertility.
2. Increased risk of gene mutation
There is also an increased risk of gene mutation in the elderly male fertility. As men grow older, their sperm will accumulate more mutations, which may be passed on to the next generation.
Research shows that there is a certain correlation between the increase of father's age and the increased risk of children suffering from certain genetic diseases. For example, when the father is over 35 years old, the risk of children suffering from autism and mental illness will increase slightly.
Therefore, when considering elderly childbearing, men should be aware of the possibility of increased risk of gene mutation, and carefully weigh the advantages and disadvantages of childbearing.
3. Increased health risk of children
Older male births also increase the health risks of children at birth. The study found that the increase in father's age was related to the increase in the incidence of health problems such as low birth weight and premature delivery at birth.
In addition, the elderly childbearing of men is also related to the increased risk of children suffering from certain genetic diseases. When the father is over 40 years old, the risk of children suffering from congenital heart disease, cleft lip and palate and other diseases will increase slightly.
Therefore, when men give birth at an advanced age, they need to pay close attention to their children's health, and carry out relevant inspections and interventions in a timely manner.
4. Influence of family and social factors
Male elder childbearing is also affected by family and social factors. On the one hand, men may have a stable economic foundation and family environment when they are old, and can provide better conditions to raise children.
However, the elderly male childbearing may also bring some psychological and life burdens. For example, with the growth of age, men's physical strength and energy may decline, which will have a certain impact on the ability and quality of caring for children.
Therefore, when considering the elderly childbearing, men need to consider their own conditions, family conditions and social influences, and make wise decisions.
Summary
The age limit of male elderly childbearing mainly depends on the decline of reproductive system function, the increase of gene mutation risk, the increase of child health risk and the influence of family and social factors. Generally speaking, male fertility declines when they are about 45 years old, and they still have high fertility when they are under 50 years old. The increase of father's age will increase the risk of children suffering from genetic diseases, as well as the incidence of health problems at birth. Male elderly childbearing needs to consider their own conditions and family environment, and pay attention to the health of their children.
