When do men count as elder children
The fertility of men will gradually decline with the growth of age, but when is it considered as an elderly child? Generally speaking, men enter the range of elderly childbearing after the age of 35. The following is a detailed description of fertility, spermatogenesis, genetic hazards and health risks.
Decline in fertility
With the growth of age, the number and quality of male sperm will gradually decline. A study showed that the sperm quality of men over 35 years old decreased by about 2% every year, and showed a trend of increasing abnormal sperm and reducing motility. This will lead to a decrease in the pregnancy rate and an increase in birth defects. Therefore, from the perspective of fertility, men over 35 years old are elderly childbearing.
In addition, men are also prone to erectile dysfunction and ejaculation problems when giving birth at an advanced age. This may be related to changes in blood circulation, hormone levels and nervous system. These problems may lead to a decline in the quality of sexual life, thus affecting fertility opportunities.
Decrease of spermatogenic ability
The sperm quality of men will not only decline with age, but also their spermatogenic ability will be affected. With the growth of age, the testicular function of men will gradually decline, and their spermatogenic capacity will also decline accordingly. In men over 35 years old, sperm activity and concentration will be reduced, which will further reduce the chance of pregnancy.
In addition, the decrease of spermatogenic ability may also lead to damage of sperm DNA and increase of mutation rate. This will increase the risk of genetic diseases and may affect the health of offspring.
Increase of genetic hazards
As men grow older, the risk of genetic hazards will also increase. Research shows that men over 35 years of age have a significantly increased risk of chromosomal abnormalities, including Down syndrome, sex chromosome abnormalities, etc. These abnormalities can be passed from male to offspring through sperm, which has a negative impact on the health of children.
In addition, older men may also increase the risk of children suffering from autism, mental illness and learning disabilities. The study found that children whose fathers are over 40 years old are more likely to suffer from these diseases. Therefore, when considering fertility, the age of men is also one of the factors to be considered.
Increased health risks
Older childbearing also has certain risks to men's health. Research shows that men over 35 are more likely to suffer from chronic diseases such as cardiovascular disease, hypertension and diabetes. These diseases not only affect the health of children, but also affect the quality of life and life span of men.
In addition, older fathers may increase the risk of children suffering from certain diseases. The study found that children whose fathers were over 45 years old had a higher risk of cancer and mental illness. Therefore, men need to be cautious about their own health when considering elderly childbearing.
Summary
To sum up, men begin to enter the range of elder childbearing after the age of 35, because their fertility and spermatogenesis will decline with age. At the same time, elderly childbearing will also increase genetic hazards and health risks, affecting the health of offspring and their own quality of life. Therefore, when considering fertility issues, the age of men is also one of the factors that need to be carefully considered.
