How old is a man?
With the development of society and the improvement of people's consciousness, more and more people begin to delay the childbearing age. In childbirth, the age of women has always been the focus of attention, but the age of men is also an important factor. So, how old is a man? This article will elaborate on this issue from different angles.
Relationship between sperm quality and age
Male reproductive capacity is related to age. With the increase of age, the number and vitality of sperm will decline, and the morphology and genetic quality of sperm will also change. Research shows that after the age of 40, the risk of abnormal sperm morphology and gene mutation is significantly increased, which may have a certain impact on the health of offspring.
In addition, the increase of age will also lead to the aging of sperm DNA, which will reduce the quality of sperm genetic information. A study published in the journal Nature Genetics shows that among men over 30 years old, there is a relatively high risk of congenital heart disease and other diseases due to sperm DNA damage.
Therefore, from the perspective of sperm quality, men can be regarded as elderly childbearing after the age of 35.
Aging of male reproductive system
The male reproductive system also ages with age. On the one hand, due to the decline of endocrine system function and testosterone secretion, semen quality and sperm number decrease. On the other hand, erectile dysfunction and difficulty in ejaculation may also occur, which will affect male fertility.
According to statistics, after the age of 40, the proportion of men with erectile dysfunction has increased significantly. In addition, about 30% of men over 60 years old suffer from problems such as difficulty in ejaculation. Therefore, from the perspective of the reproductive system, men after 40 can be considered as elderly childbearing.
The relationship between children's health and father's age
In addition to affecting the male's own reproductive capacity, the father's age will also have an impact on the health of children. The study found that the increase of father's age is related to the increased risk of some genetic diseases, autism and mental disorders.
A study published in the Journal of the American Medical Association pointed out that if the father is over 35 years old, the risk of children suffering from autism is twice as high as that of young fathers. In addition, the growth of father's age is also related to low birth weight, premature delivery and neural tube defects.
Therefore, from the perspective of children's health, men can be regarded as elderly childbearing after the age of 35.
Opinions and suggestions of the hospital
Different hospitals have slightly different definitions of male elderly childbearing. Take the famous Massachusetts General Hospital in the United States as an example. They believe that a man who gives birth after the age of 35 can be regarded as an elderly child. In China, some large obstetric and gynaecological hospitals also regard the age of 35 as the dividing line for men's elderly childbearing.
Some hospitals have put forward some suggestions in the face of elderly male childbearing. First of all, men should carry out fertility awareness education in advance, be aware of the impact of age on fertility, and consult relevant doctors in a timely manner. Secondly, conduct a comprehensive physical examination on a regular basis to understand the status of their fertility. Moreover, keep good living habits and healthy lifestyle, such as smoking cessation, alcohol abstinence, balanced diet, proper exercise, etc.
To sum up, men can be regarded as elderly childbearing after the age of 35. With the growth of age, the male reproductive capacity and sperm quality will decline, and the reproductive system will also appear aging. At the same time, the increase of father's age will also have an impact on the health of children. Therefore, it is suggested that men should carry out fertility consultation at an early stage, maintain good living habits and arrange fertility plans as soon as possible.
