The Influence of Male Elderly Childbearing on Fertility
With the development of society, more and more men are postponing childbearing, which is also called "elder male childbearing". However, male fertility declines with age, which has aroused people's concern. This article will discuss the influence of male aging fertility on fertility from four aspects: reproductive health, sperm quality, genetic diseases and fertility success rate.
1. Reproductive health
The function of male reproductive organs, including testes, epididymis and spermatogenic cells, decreases with age. This will lead to a decline in the yield and quality of sperm, thus affecting fertility. A study found that the testosterone level of men over 50 years old decreased significantly, and the number and quality of normal sperm also decreased. Therefore, the fertility of older men will be affected.
In addition, the elderly childbearing of men is also related to the increased risk of various reproductive system diseases. For example, prostatic hyperplasia, testicular tumor, spermatogenic cytopenia, etc. These diseases not only have a direct impact on fertility, but also may cause other health problems, thus affecting the success rate of fertility.
2. Sperm quality
The elderly male fertility has a significant impact on sperm quality. Studies have shown that with the increase of age, sperm morphological abnormalities and DNA damage rate will significantly increase, thereby reducing sperm quality. This will lead to a decline in sperm activity, affecting its ability to combine with eggs and fertilize.
In addition, the increase in age will also lead to a decrease in the proportion of normal sperm in semen and an increase in the proportion of abnormal sperm. This will also have a negative impact on fertility. Therefore, the elderly male fertility is often accompanied by a decline in sperm quality, which reduces the possibility of pregnancy.
3. Genetic diseases
With the increase of age, the risk of genetic diseases is also increased by the aging of men. Research shows that when the father is over 40 years old, the risk of children suffering from autism, mental illness and some congenital diseases increases significantly. This is because old men will lead to the accumulation of abnormal genes in their sperm, which will increase the risk of children's disease.
Compared with women, male germ cells divide more frequently, so the probability of abnormal genes is relatively large. The elderly male fertility prolongs the cycle of sperm formation, makes the accumulation of abnormal genes more significant, and increases the risk of transmission of genetic diseases.
4. Fertility success rate
The elderly male fertility will also have a certain impact on the fertility success rate. Research shows that there is a certain correlation between the father's too old age and poor pregnancy outcomes (such as premature delivery, low birth weight, etc.). This is because old men will lead to a decline in the function of the reproductive system, thus affecting the process of fertilization and embryo embedding.
In addition, older men also increase the risk of complications during pregnancy, such as pregnancy induced hypertension and diabetes. These complications will not only affect the mother, but also may affect the development and health of the fetus.
Summary
The elderly male fertility has many effects on fertility. First, it will lead to reproductive health damage, including decreased reproductive organ function and increased risk of reproductive system diseases. Secondly, it will affect the quality of sperm, leading to the decline of sperm activity and fertilization ability. In addition, the risk of genetic diseases will also increase when men are old enough to give birth. Finally, it will reduce the success rate of fertility and increase the risk of adverse pregnancy outcomes and pregnancy complications.
Therefore, it is necessary for men to be cautious about giving birth at an advanced age. When making fertility decisions, men should fully understand their fertility status and consult doctors when necessary to obtain professional advice and guidance.
