The influence of elderly male fertility

The male reproductive function gradually weakens with the increase of age, which will have a certain impact on the fertility of older men. The following is a detailed description of the relationship between male elderly fertility and genetic diseases from sperm quality, chromosome abnormalities, transmission of genetic diseases and child health.

1. The sperm quality decreases

With the increase of age, the sperm quality of men generally declined. The study found that the number, vitality and abnormal morphological rate of sperm in elderly men would increase. This means that the sperm of the elderly father may have problems such as DNA damage and chromosome abnormalities, which increases the risk of genetic diseases.

The decrease of sperm quality will not only affect the probability of pregnancy, but also increase the probability of abnormal embryonic development, early abortion and fetal malformation. Therefore, it is also necessary to be alert to the related genetic problems in the elderly male fertility.

2. Chromosome abnormalities increase

There is also a close relationship between the elderly male fertility and chromosomal abnormalities. Studies have shown that the incidence of chromosomal abnormalities in male sperm gradually increases with age, especially common chromosomal abnormalities such as Down syndrome.

Chromosome abnormalities can cause a variety of genetic diseases, such as mental retardation, growth retardation, heart and other organ abnormalities. These abnormal diseases may have long-term adverse effects on children's quality of life and health.

3. Risk of genetic disease transmission

As we all know, genetic diseases are not only related to the mother's genetic genes, but also the father's genetic genes have an impact on the child's health. When men give birth at an advanced age, the risk of children suffering from genetic diseases will also increase due to the increase of sperm quality and chromosome abnormalities.

Some common genetic diseases, such as congenital heart disease, hereditary kidney disease, hereditary cancer, etc., may be passed from father to child. Therefore, the male elderly child-bearing people should pay attention to their own genetic disease history, and carry out genetic counseling and related gene testing in time to reduce the risk of disease.

4. Health problems of children

The elderly male childbearing also has a certain impact on the health of children. The study found that the children of older fathers are more likely to have premature delivery, low weight, congenital malformations and other problems. These health problems are closely related to sperm quality decline, chromosome abnormalities and other factors.

In addition, because older fathers may face more health problems during the growth of their children, such as heart disease, diabetes, etc., this may also bring additional problems to the child's upbringing and growth.

Summary

There is a close relationship between the elderly male fertility and genetic diseases. The decline of sperm quality, the increase of chromosomal abnormalities, the risk of transmission of genetic diseases and the health problems of children are all possible challenges that men may face in their advanced childbearing. Therefore, men should fully understand the relevant risks when considering elderly childbearing, and conduct comprehensive testing and consultation under the guidance of doctors.
