Reasons for the decline of male fertility in the elderly
With the development of society, more and more men choose to marry later and have children later. However, the fertility of older men is facing some challenges. This article will elaborate on the reasons for the decline of male fertility in the elderly from four aspects: physiological changes, chronic diseases, lifestyle and environmental factors.
Physiological changes
With the growth of age, a series of physiological changes will occur in the male reproductive system, which will lead to the reduction of fertility. First, the number and quality of sperm will gradually decrease. Research shows that the number and vitality of sperm of men over 40 years old are significantly reduced, and the proportion of deformed sperm will also increase. Secondly, with the increase of age, the testicular function of men will gradually decline, and the testosterone level will decline, thus affecting the production and maturation of sperm. In addition, male ejaculation function will also be affected, including delayed ejaculation or weak ejaculation.
In view of the impact of physiological changes on male fertility, it is suggested that men should make plans as early as possible in family planning to avoid the problems caused by elderly childbearing.
chronic disease
Chronic diseases are another important reason for the reduction of male fertility at an advanced age. For example, chronic diseases such as cardiovascular disease, diabetes and hypertension will have a negative impact on the male reproductive system. These diseases can cause vasoconstriction, tissue oxidative stress, endocrine disorders and other problems, thus affecting testicular function and spermatogenesis. In addition, chronic diseases are often accompanied by long-term drug treatment, which may also have adverse effects on fertility.
Therefore, men should ensure their health before family planning, seek medical advice as soon as possible in terms of reproductive system problems, control chronic diseases in time, and avoid adverse effects on fertility.
life style
The decline in male fertility at an advanced age is closely related to lifestyle. Bad living habits, such as smoking, excessive drinking and unhealthy diet, will have a negative impact on male fertility. Smoking will lead to a decline in the number and quality of sperm and increase the proportion of deformed sperm. Excessive drinking will affect the normal function of the testis, thus interfering with sperm production. Unhealthy eating habits will lead to obesity, diabetes and other problems, which will affect the normal operation of the reproductive system.
In order to maintain good fertility, men should develop healthy living habits, quit smoking and limit alcohol consumption, maintain proper weight, and eat a balanced diet.
environmental factor
Environmental factors will also have a certain impact on the fertility of older men. For example, radiation and pollutants may cause damage to the male reproductive system. Ionizing radiation, chemicals, heavy metals and other environmental pollutants can interfere with sperm production and development, thus reducing fertility.
In order to reduce the harm of environmental factors on fertility, men should try to avoid contacting harmful substances in their work and living environment and maintain good environmental sanitation.
conclusion
The decline of male fertility in the elderly can be attributed to physiological changes, chronic diseases, lifestyle and environmental factors. Understanding these reasons can help men take measures as soon as possible to improve their fertility. Maintaining a healthy lifestyle, preventing chronic diseases and reducing exposure to adverse environmental factors are all important ways to improve male fertility. Men should pay attention to these problems before family planning to avoid the problems caused by elderly childbearing.
