How old do men start to have high fertility risk
With the continuous development of society, more and more couples choose late childbearing. However, men will also face the risk of elderly childbearing after a certain age. So, at what age do men begin to be at risk of having an older child? This article will elaborate from physiological, psychological, genetic and medical aspects.
Physiological aspects
From a physiological point of view, male reproductive function will change with age. The study found that the number and quality of men's sperm will gradually decline, and the older the man, the higher the probability of abnormal sperm. In addition, with the increase of age, the testicular function and hormone level of men will also change, affecting the production and quality of sperm in the testis.
In a study of more than 10000 couples, it was found that the fertility of men in the age group of 40 years and above was reduced by more than 30% compared with men under 30 years old. This is because with the growth of age, male sperm DNA is vulnerable to oxidative stress and other environmental factors, leading to fertility disorders.
In addition, the increase of male age is also related to the decline of fertility rate, the increase of abortion rate and the rise of fetal abnormality rate. Therefore, after the age of 30, men will gradually face the risk of elderly childbearing.
Psychological aspects
Men also face psychological pressure in terms of elderly childbearing. Compared with women, men's reproductive capacity can remain relatively stable for a longer period of time, but as they grow older, they may feel the pressure of time and fear that they cannot meet their own and their partners' reproductive needs.
In addition, the elderly male childbearing will also lead to some psychological problems, such as anxiety, depression and inferiority complex. Men may worry about their fertility and whether they are competent for the role of father, and even worry about their partner's physical condition and the health of the fetus.
Therefore, men should fully communicate with their partners before giving birth at an advanced age, understand each other's needs and psychological pressure, and jointly cope with the psychological challenges brought by the advanced birth.
Genetic aspects
There are also genetic risks in male elderly childbearing. Research shows that the increase of father's age is related to the increase of some gene mutations and the incidence of genetic diseases. These genetic variations may lead to an increased risk of congenital diseases at birth, such as Down syndrome, autism and mental illness.
A study of more than 50000 children found that children whose fathers were over 40 years old were six times more likely to suffer from autism than those whose fathers were under 20 years old. In addition, the older the father, the higher the risk of children suffering from genetic diseases.
Therefore, men should pay attention to the genetic risk when considering elderly childbearing. They can carry out relevant gene testing before pregnancy to understand their own genetic status and discuss the possible risks with doctors.
Medical aspects
Men also need to consider medical factors when giving birth at an advanced age. As men grow older, they may suffer from some chronic diseases, such as hypertension, diabetes and heart disease. These diseases may affect male reproductive function and increase the risk of pregnancy and childbirth.
In addition, men also need to pay attention to the health of their partners when giving birth at an advanced age. The fertility of women will also decline with the increase of age, and they are more likely to have pregnancy complications and fetal abnormalities when they are in the advanced age.
Therefore, when deciding to give birth at an advanced age, men should consult with doctors in detail to understand the medical risks of themselves and their partners, and make cautious decisions according to the specific circumstances.
Summary
After the age of 30, men begin to have the risk of elder childbearing, which is related to many factors in physical, psychological, genetic and medical aspects. With the increase of age, male reproductive function will change, sperm quality and quantity will decline, and sperm DNA is vulnerable to damage. At the same time, men will also face psychological pressure and genetic risks, affecting fertility and fetal health. Medical factors also need to be considered. Chronic diseases of men and women may affect the safety of childbirth. Therefore, before giving birth at an advanced age, men should carefully consider their own physiological and psychological conditions, fully understand the genetic risks, and consult and make decisions with doctors to ensure the safety and health of childbirth.
