When do men want children? The golden reproductive age of men.
It is known that it is dangerous for women to have children after childbearing age. So, is there any regulation about male reproductive age for male health care? What is the best reproductive age for men? The guide to men's health helps you reveal the secret.
When do men want their children to have a good baby? Prime time.
Men and women have reproductive biological clocks. Although the reproductive life of men is much longer than that of women, from the perspective of eugenics, the age of men as fathers should not exceed 35.
As we all know, women have a strict reproductive biological clock. Once over 35 years old, not only fertility declines, but also the risk of giving birth to a defective fetus (such as congenital stupidity) will increase. By menopause, menstruation has stopped, ovulation has stopped, and it has become an ironclad fact that there is no reproductive opportunity.
What about men? But it is another kind of "landscape", and its fertility is relatively limited by age.
In life, the news that men are "born 80 years old" has been heard from time to time. Therefore, it is generally believed that in terms of reproduction, the age of the father is not so important as the age of the mother. However, experts remind that from the perspective of eugenics, 25 to 35 years old is the golden childbearing age for men.
American scientists have found that 35 years old is the watershed of male sperm quality. Taking sperm quality as an example, although the sperm of elderly men are not aging and have high density, the genetic variation rate in sperm is greatly increased, the sperm vitality is obviously decreased, and the number of immobile and abnormal sperm is increased by 20%.
Not only that, the speed of sperm metabolism has also decreased, and a large amount of waste has been produced after metabolism, which has a negative impact on fertility.
With the increase of men's age, the ability of sperm to conceive eggs is greatly reduced. At the same time, after the age of 35, the androgen in the body also began to decline, and the secretion of testosterone decreased by 1% every year.
Therefore, like women, men also have a reproductive "biological clock", but the male reproductive "biological clock" is more flexible.
The "Fertility Risk" of Old Men
Decreased sperm quality
Research conducted by scientists among 654.38 million+children found that children born to older fathers are more likely to suffer from congenital defects and related diseases, thus increasing the risk of premature death.
This study, published in the latest issue of European Epidemiology Monthly, is the largest study in related fields in the West. The researchers believe that this result is related to the decline of male sperm quality with age.
The researchers also found that children born to older fathers were more likely to die in accidents than other children compared with fathers aged 25 to 30. Researchers believe that this may be because these children are more likely to suffer from autism, epilepsy and schizophrenia, thus increasing the possibility of fatal accidents.
Most of the scientific research on elderly parents focuses on the risk of the mother being too old. However, this new study reveals the reproductive risks brought by elderly fathers.
It's not good to have children too early.
The study also found that if you become a father too early, for example, if you give birth to a child under 19, the risk of death of the child born is also higher than that of the child born at the normal age of 25-30.
Other studies have shown that older men are four times more likely to give birth to Down syndrome than fathers of normal age. Another study shows that as men get older, their sperm quality will also decline.
There are more than 75,000 children born to fathers over 40 in Britain, accounting for110 of the birth rate in Britain. Among them, 6,000 babies were born to fathers over 50 years old. The average age of fathers in Britain is 32.
Reasonable diet improves male fertility
1, eat a pledge containing magnesium.
Magnesium helps to regulate human heart activity, lower blood pressure, prevent heart disease and improve male fertility. It is recommended that men eat 2 bowls of oatmeal with milk for breakfast. 1 banana. Foods containing more magnesium include soybeans, potatoes, walnuts, oatmeal, macaroni, leafy vegetables and seafood.
2. Arginine is the main component produced by sperm head, and the ability of sperm activity should be improved.
Arginine-rich tokens include sea cucumber, eel, loach, cuttlefish, sesame, yam, ginkgo, bean curd skin, frozen bean curd, peanut kernel, sunflower seed and hazelnut. Sea cucumber, for example, has been regarded as a treasure for tonifying kidney and essence, strengthening yang and treating impotence since ancient times.
3. Sperm is rich in trace element zinc, which plays an important role in maintaining the reproductive function of male political parties.
Because zinc is an essential substance for sperm metabolism and can enhance sperm motility, you should eat more zinc-rich keepsakes, such as oysters, shrimps, clams, shellfish, animal livers, walnuts, milk, beans, bran and lotus seeds. The content of zinc in oyster meat is the highest of all things. Paying attention to the intake of sperm nucleic acid and protein metabolism can improve sexual ability. However, the daily intake of zinc should not exceed 15 micrograms, because excessive use of zinc will affect the role of other minerals in the human body. 120g lean meat contains 7.5 micrograms of zinc.
4. Calcium plays an important role in sperm motility, capacitation, maintaining hyaluronidase activity and fertilization.
If the body lacks calcium, it will slow down sperm movement and reduce the activity of sperm acrosin. Therefore, men should also pay attention to eating more calcium-rich tokens, such as milk, bean products, sushi fish, sparerib soup, laver, shrimp skin, kelp, Undaria pinnatifida, day lily, mushrooms, mustard greens, coriander, sweet almonds, raisins and so on.
5. In addition, the activity of sperm is related to the amount of fructose contained in seminal vesicle.
If the fructose content in semen is low, it is easy to cause azoospermia. Honey and various fruits are rich in fructose, such as pears, apples, grapes, pineapples, sweet oranges, etc., so pay attention to the letter. Products recommended by traditional Chinese medicine in past dynasties, such as river shrimp, sparrow meat, beef, dog meat, swim bladder, walnut, leek and medlar, are also optional.
