How old is a man?
With the social progress and the improvement of living standards, more and more couples have begun to pay attention to fertility. Compared with women, male fertility is less restricted. However, male fertility will also decline with age. So, how old is a man? The following will elaborate from four aspects: reproductive capacity, genetic problems, maternal and infant health and psychological factors.
1、 Reproductive capacity
Male reproductive capacity mainly includes sperm quantity, sperm quality and sperm motility. With the increase of age, the testicular function of men begins to decline, and the number and activity of sperm will also decrease. Research shows that the proportion of sperm number and activity decline is higher among men over 40 years old. The decrease of sperm quality will increase the risk of pregnancy failure and fetal malformation. Therefore, from the perspective of reproductive capacity, men over 40 years old can be considered as elderly childbearing.
In addition, male fertility is also affected by other factors, such as reproductive system diseases, sexual dysfunction, etc. These problems may increase with age, further reducing male fertility.
2、 Genetic problems
Male age also affects the genetic quality of offspring. With the growth of age, male sperm will accumulate more gene mutations, thus increasing the risk of children suffering from genetic diseases. For example, when a father is over 40 years old, the risk of his children suffering from autism and schizophrenia will increase significantly. Therefore, from the perspective of genetic problems, men over 40 can also be considered as elderly childbearing.
3、 Maternity and infant health
The age of men is also related to the health status and development ability of children. The study found that when the father was older, the risk of low birth weight and premature delivery increased. At the same time, older fathers are also related to children's cognitive ability and language development. Therefore, from the perspective of paying attention to the health of pregnant women and infants, the number of years old for men can be referred to the age of 40 or above.
In addition, older men are also associated with an increased risk of complications during pregnancy and childbirth. For example, when the father is over 45 years old, it may increase the risk of maternal and infant death and gestational diabetes. Therefore, considering the comprehensive factors of pregnancy and infant health, men over 40 years old can be regarded as elderly childbearing.
4、 Psychological factors
The age of men also has an important influence on fertility, that is, psychological factors. With the growth of age, men may face more pressure and anxiety, worried about their fertility and genetic problems of their offspring. This kind of psychological pressure may affect the relationship between husband and wife and fertility decision-making, and then affect the implementation of fertility. Therefore, considering the mental health of men, men over 40 years old can also be regarded as elderly in terms of fertility.
Summary
To sum up, it is a comprehensive consideration of multiple factors that how old a man is when he gives birth. From the perspective of reproductive capacity, genetic problems, maternal and infant health and psychological factors, men over 40 years old can be regarded as elderly childbearing. However, this does not mean that men over the age of 40 cannot have children, but it is suggested that they should be more cautious and comprehensive in their fertility issues to avoid unnecessary risks to themselves and their families due to age growth.
