It is a major event that human beings can continue.In the past, people's eyes were basically locked on their wives. In fact, the husband was also a pivotal party, so it is necessary to understand the fertility knowledge of some men.To this end, this article introduces some new claims of scientists, are you interested in?
Men's fertility life is not capped
There is a saying that you are familiar with: 41 men, and women's forty soybean dregs.Female friends are definitely uncomfortable when they listen, but if you refer to reproductive ability, it really makes sense, you have to convince it.The mystery is that women have strict reproductive biological clocks. Once they are over 35 or 40 years old, they will not only have a landslide of fertility, but also the risk of defective fetuses (such as congenital stupidity) will also increase.Caused by mutations.As for the 50 years of age, menstruation is broken, ovulation stops, and it becomes a factual fact that if it is not known as fertility.
What about men?But it is another "landscape line", and the possibility of fertility is less likely to be limited.Jun did not see the news of the age of 90 or even a centenarians.In Chinese ancient books, there are long records of "eighty old people". In modern times, there are also alive examples. For example, a Shousan, who was nearly 90 years old 20 years ago, liked his father.Foreign abroad is not uncommon. For example, there is a 120 -year -old man in Sweden. He married again at the age of 85 and gave birth to 8 children. A former Soviet Union was called Ahamr?The peasants in Bhanania were married and had children at the age of 112. This is probably the Guinness record for older men in the world.
It is not difficult to understand that men's fertility life is not capped.Is there any scientific evidence?Munich experts in Munich, Germany, were observed with 20 elderly men aged 60 to 89 and 20 to 33 -year -old men, each tested their semen and compared them. The results showed that the sperm of elderly men was not aging, andThe density of sperm (average of 120 million semen per milliliter) is also high (an average of only 78 million semen per milliliter semen).It seems that to describe the fertility of elderly men with old age, it is not too much.
Men also have reproductive biological clocks
Although men's fertility periods are much longer than women, and they are almost lifetime, from the perspective of eugenics, there are still the best age groups.Taking the quality of sperm as an example, although the sperm of the elderly men is not aging and the density is also high, the activity ability has been significantly reduced.After the decline, many wastes have been produced after metabolism, which can be imagined on the adverse effects of future generations.
In addition, the man is 35 years old, and the male hormones in the body are also attenuated, and the amount of testosterone secretion is reduced by 1%every year after a year.Therefore, like women, men also have reproductive biological clocks, but men's reproductive biological clocks are more flexible.
According to the law of men's reproductive bells, when is the best for men to be a father?A French professor named Xielitz investigated 2,000 soldiers in the country and found that children born in the age of 30 to 35 are the highest in the intellectual test.His conclusion is that men aged 30 to 35 have the most powerful vitality and are the most suitable for fertility.
This statement was verified by French geneticist Merisia.Research by Morice shows that children born in the age of 30 to 35 are the best children.The explanation is that the quality of men reached the highest peak at the age of 30, and then for 5 years to 35 years old, and then the quality declined.
Bi Hua, an obstetrics and gynecologist in the United States, also determined that men in their 30s are "best dads."Because of this time, in addition to the advantages of physical fitness, there are also characteristics of stable career, good economic conditions, and superior conditions for raising children.
Take a reality example, you must know that Mrsachel, who has been re -elected as the three British Prime Minister and enjoys the iron lady of politics.Intersection32 years old, just in the best age group of men!
