How old is a man?
With the development of society and the gradual change of people's expectations for families, more and more men begin to delay the age of childbearing. However, the age of men also has an impact on fertility. So, how old are men? This article will elaborate from four aspects: reproductive health, fertility, genetic risk and medical practice.
1. Reproductive health
The male reproductive system will change with age. With the increase of age, the number and quality of male sperm will gradually decline. Research shows that the fertility of men over 40 years old begins to decline. Therefore, it is generally believed that men enter the range of elderly childbearing after the age of 40.
In addition, with the growth of age, the male reproductive system may also have other problems, such as erectile dysfunction and increased risk of disease. These problems may affect men's fertility and their ability to assume the role of father after childbirth.
In general, male reproductive health began to decline significantly after the age of 40. Therefore, the age of 40 can be used as the boundary for male elderly childbearing.
2. Fertility
In addition to reproductive health, male fertility is also affected by age. Research shows that the number and quality of men's sperm gradually decline after the age of 40, thus increasing the risk of fertility disorders. In addition, aging may also lead to sperm DNA damage and chromosome abnormalities, which increase the risk of genetic diseases.
In addition, the age of men is also related to some complications during childbirth. For example, research shows that the older the father is, the lower the child's weight at birth, and the higher the risk of premature delivery and stillbirth. In addition, the father's too old may also be associated with the increased risk of children's intellectual development, autism and other neurodevelopmental disorders.
To sum up, male fertility has significantly declined after the age of 40. In addition, it is associated with complications and genetic risks in the reproductive process. Therefore, male fertility above 40 can be regarded as an elderly birth.
3. Genetic risk
The increase of age not only affects the male's own fertility, but also increases the risk of genetic diseases in children. Studies have shown that the age of men is related to genetic factors such as chromosomal abnormalities, mutations of lone male warriors and single gene genetic diseases.
According to medical practice data, when the father is over 35 years old, the risk of chromosomal abnormalities increases significantly. Chromosome abnormalities may lead to fetal chromosomal diseases, such as Down syndrome. In addition, the older the father, the higher the risk of mutation of the lone male warrior. The mutation of a lone male warrior refers to a new mutation in paternal inheritance, while the mother's gene has not changed. This mutation may lead to a series of genetic diseases, such as autism and mental illness.
Therefore, the elderly childbearing of men will not only affect their own fertility, but also increase the risk of children's genetic diseases.
4. Medical practice
Many studies in medical practice have confirmed the influence of male age on fertility and children's health. Many hospitals have also started to provide male reproductive health examination and counseling services. For example, a well-known hospital in China has set up a reproductive health clinic to provide relevant inspection and consultation services for men over 40 years of age to help them understand their fertility and genetic risks, so as to make more informed decisions.
Therefore, men can be regarded as elderly childbearing after the age of 40. It is recommended that they take their own reproductive health, fertility and genetic risks into full consideration when deciding to give birth, and seek the advice and guidance of professional doctors when necessary.
Summary
How old is a man? From the perspective of reproductive health, fertility, genetic risk and medical practice, it is generally believed that men after the age of 40 can be regarded as elderly childbearing. With the increase of age, male fertility declines, which is related to the increase of complications and genetic risks in the reproductive process. Relevant services are also provided in medical practice to help men understand their fertility and genetic risks. Therefore, it is suggested that men should carefully consider various factors, such as reproductive health, fertility and genetic risks, when making fertility decisions after the age of 40.
