The risk of male elderly childbearing: How old are men more dangerous to have children?
The elderly male childbearing has always been a topic of great concern. With the change of modern society, more and more men choose to marry later and have children later, but the growth of age is accompanied by the increase of fertility risk. So, at what age is it more dangerous for men to have children? This article will elaborate on the risks of male elderly childbearing from many aspects.
1. Decreased reproductive capacity
With the increase of age, the male reproductive capacity will gradually decline. According to several medical studies, the number, quality and vitality of sperm will be affected by age. A study conducted by the U.S. Department of Health and Human Services found that the number and vitality of men's sperm will gradually decrease after the age of 35. This means that the sperm quality may be low when men are old enough to give birth, thus increasing the risk of birth abnormalities.
In addition to the decline in sperm quality, the elderly men may also face the risk of chromosomal abnormalities. The study found that children born to men over 40 years old have a higher risk of chromosomal diseases (such as Down syndrome) than children born to mothers of the same age.
In addition, the elderly male fertility is also related to low quality sperm DNA, which may increase the risk of some diseases (such as autism and mental illness) in offspring.
2. Increase the risk of children's health problems
Old age childbearing of men not only risks their own fertility, but also affects the health of their offspring. For example, older men's childbearing is related to lower birth weight. A large-scale study in Sweden found that children born to fathers over 35 years old were generally lower in weight at birth than those born to fathers under 30 years old.
In addition, male elder childbearing is also related to the increased risk of children suffering from certain diseases. For example, research shows that children born to men over the age of 40 have a higher risk of autism than children born to young fathers.
To sum up, the elderly male childbirth will increase the risk of low birth weight and certain diseases.
3. Increase the risk of maternal complications
The elderly childbearing of men not only risks themselves and their offspring, but also increases the risk of maternal complications. An analysis of British hospital data shows that mothers of children born to men over 40 are more likely to suffer from complications such as pregnancy induced hypertension, diabetes and placental abruption.
In addition, older male births are also associated with an increased risk of preterm birth and low birth weight infants. A Swedish study found that compared with fathers under 30 years old, fathers over 40 years old are more likely to have premature babies and lower birth weight.
To sum up, the elderly male childbirth will increase the risk of maternal complications, including pregnancy induced hypertension, diabetes, etc., and may lead to premature delivery and the birth of low weight infants.
4. Influence of father's role
Male elder childbearing also involves the role of father. With the growth of age, fathers may face more physical and mental health problems, which may affect their care and education of children. In addition, the age gap between parents may also affect the stability of the family and the growth environment of children.
In general, there are many risks for men's elderly childbearing, including decreased reproductive capacity, increased child health problems, increased risk of maternal complications, and the impact of the role of father. Therefore, when considering the time of childbearing, men should comprehensively consider relevant health factors to reduce risks and give children a better health and growth environment.
