The relationship between male elder childbearing and infertility
With the progress of society and the development of medical technology, the elderly male childbearing has gradually become a trend. However, will it increase the risk of infertility due to the aging of men? This article will elaborate on the relationship between male elderly fertility and infertility from four aspects of physiology, genetics, lifestyle and environmental pollution.
Physiological factors
There is a physiological correlation between male elderly fertility and infertility. With the increase of age, the function of male reproductive system will gradually decline. The study found that the quality and quantity of male sperm will decrease with age. The proportion of abnormal sperm activity and morphology in elderly men will also increase, which may lead to the decline of sperm egg binding ability, thus increasing the incidence of infertility.
In addition, the aging of male fertility is also associated with the decline of testicular function and the risk of testicular tumors. The testicle is the organ responsible for producing sperm in the male reproductive system. The degradation of testicular function may lead to the decline of sperm quality. At the same time, the incidence of testicular tumors also increases with age, which will have a negative impact on sperm, thereby increasing the risk of infertility.
In general, the elderly male fertility will have a certain impact on physiological factors, thus increasing the risk of infertility.
Genetic factor
Genetic factors are also an important link between male fertility at an advanced age and infertility. The risk of chromosomal abnormalities and genetic diseases in older men and their offspring increased significantly. For example, the association between older fathers and children with autism has been confirmed by many studies. In addition, the old age of men is also related to the increased incidence of congenital heart disease, Down syndrome and other genetic diseases.
This is because the male sperm will have DNA mutation and damage in the process of division and replication. With age, the accumulation of these mutations and injuries will lead to sperm carrying abnormal chromosomes or genes. When these abnormal sperm combine with the egg, there may be a risk of genetic diseases during embryonic development.
life style
The relationship between male elderly childbearing and infertility is also related to lifestyle. Older men usually have more life pressure and work pressure, which may lead to changes in hormone levels. Research shows that both work pressure and environmental pressure can affect the quality and quantity of sperm. In addition, elderly men are often accompanied by bad living habits, such as smoking, drinking and lack of exercise. These unhealthy lifestyles will also have a negative impact on fertility.
In addition, the metabolic function of elderly men will also change. With the growth of age, the production of antioxidants in men decreases, leading to the increase of reactive oxygen species, which will damage the quality of sperm. In addition, changes in diet structure and nutrition intake may reduce male fertility.
environmental pollution
Finally, environmental pollution is also one of the reasons for infertility caused by male elderly childbearing. Long term exposure to pollutants, such as heavy metals, pesticides and other chemicals, will have a negative impact on male fertility. These pollutants can directly damage sperm DNA, thereby reducing sperm quality. Some studies also found that there was a clear correlation between environmental pollution and the reduction of sperm number and the increase of sperm abnormalities.
To sum up, the elderly male fertility may increase the risk of infertility. Physiological factors, genetic factors, lifestyle and environmental pollution are all related to male aging fertility and infertility. Therefore, before men decide to give birth at an advanced age, they should seriously consider these factors, and timely seek medical advice and conduct relevant tests to ensure the safety and smoothness of childbirth.
Summary
There is a close relationship between male elder childbearing and infertility. Physiological factors, genetic factors, lifestyle and environmental pollution may all lead to infertility. When giving birth to elderly men, they should pay attention to the adjustment of their physical condition and lifestyle, reasonably arrange the birth plan, and seek help and advice from professional hospitals when necessary.
