The Mechanism of Male Fertility in the Elderly
With the development of society, more and more men choose to delay childbearing, and the mechanism of male elderly fertility has become a topic of concern. This article will elaborate on the mechanism of male fertility at an advanced age from the aspects of male reproductive system, genetic factors, lifestyle and environmental factors.
Male reproductive system
Male fertility is mainly related to the quality and quantity of sperm. With the increase of age, the quality and quantity of male sperm will gradually decline. Because the production of sperm takes a certain time, in this process, sperm will be exposed to environmental factors, such as ultraviolet light, high temperature, etc. These factors will damage sperm DNA, leading to a decline in its quality. In addition, the number of sperm will also be affected, because with the increase of age, the ability of sperm production in the testis will gradually weaken.
In addition, male reproductive organs are also affected by age. With the increase of age, the male reproductive organs gradually age, such as the decrease of the elasticity of the penis blood vessels and the rise of the scrotal temperature, which will affect the production and quality of sperm.
In addition, men's sex hormone levels are also affected by age. With the increase of age, the testicular function of men will gradually weaken, leading to the reduction of testosterone and other male hormones, which will also affect the fertility of men.
Genetic factor
Genetic factors also play an important role in the mechanism of male fertility at an advanced age. There is a high DNA damage rate in male sperm. With the growth of age, DNA repair ability will decline, resulting in more DNA damage can not be repaired. Such DNA damage will affect the quality and quantity of sperm, thus reducing male fertility.
In addition, the elderly male fertility will also increase the risk of some genetic diseases. Research shows that older fathers will increase the prevalence of children's congenital diseases, such as Down syndrome and autism. This is because there may be some mutations in the father's sperm, which will increase with age.
life style
Life style also plays an important role in the mechanism of male fertility at an advanced age. Unhealthy lifestyle will have adverse effects on the quality and quantity of sperm. Long term smoking and excessive drinking will lead to DNA damage of sperm and affect the quality of sperm. Unreasonable diet and lack of exercise will lead to obesity, which will adversely affect the quality and quantity of sperm. In addition, long-term exposure to high temperature environment will also have a negative impact on sperm.
environmental factor
The environmental factor is also an important factor in the mechanism of male fertility. In modern life, men will be exposed to various environmental pollutants, such as heavy metals, pesticides, etc. These environmental pollutants will damage sperm and affect the quality of sperm. In addition, electromagnetic radiation and computer radiation will also have adverse effects on male fertility.
To sum up, the mechanism of male elderly fertility is mainly reflected in male reproductive system, genetic factors, lifestyle and environmental factors. With the growth of age, male fertility will gradually decline. Therefore, when choosing the time of birth, men should pay attention to the early birth to avoid the risk of old age birth.
