Laofushaoqi child really is more clever?

Society, a kind of popular - Laofushaoqi children born more intelligent, and even cases show that the reason why some big celebrity wise, that is, because of their father, mother, older than many.



Laofushaoqi Most kids really clever?



Congenital smart kids or not, the final analysis, fertility quality problems, that is, sperm and eggs must be tough, only high quality embryos.





Let me talk about the egg.

All along, the medical profession has reached a consensus that women over 35 years old, not only the decline in fertility, and chromosome increases with age, the possibility of mutations increased risk of birth defects in the fetus will increase. Therefore, women 35 years of age is a relatively clear time limits section of older mothers is also based on the so-called "35 years old" as the definition.



Revisit the sperm.

U.S. Male Reproductive Center at Columbia University, New York, director of Harry believed that men over 30 years of age, the average every passing year, the amount of testosterone secretion but dropped 1 percent, which means that men's fertility decreases with increasing age; the other Some researchers say that, the number of sperm will reduce after the age of 50, but this decrease is not statistically significant clinical importance, it does not affect male fertility, even if it only generates a sperm of men, as long as It can become pregnant, then men also have a reproductive capacity.



Zhejiang Institute of Science and Technology of family planning, said Professor Yao Kangshou, with his clinical experience and research, men generally in the 40 years of age, the amount of testosterone secretion began to decline, sperm quantity and quality to decline.



Decline in the quality of sperm, then the next generation of hereditary diseases likely to increase, such as Down's syndrome (also known as Down's syndrome), which is a kind ofFeeblemindednessThe most common chromosomal disease, which previously thought to be diseases caused by older mothers, and now with her father's age was found to have a great relationship. Studies have found that women over 40 years of age, while men over the age of 35 years of age, if their child suffering from Down's syndrome, about 50% of its responsibilities related with the sperm.



From reproductive studies, said that older men, poor sperm quality, more and more genetic variation is also "a child born Laofushaoqi smarter" was unscientific. However, from sociological point of view, this argument has some truth. Provincial Family Planning Research Institute of Science and Technology Professor Yao Kangshou that Laofushaoqi Most of the households economic stability, quality of life high, pregnant women during pregnancy, nutrition, mood will be better, so that the basis of fetal congenital better, another children's education acquired culture conditions than the average family is good, clever also normal
