"Older women are not good for the health of babies and mothers"-this is a point that many people are aware of. But for the elderly father, people pay little attention to it.
In fact, behind almost every elderly expectant mother, there will be an elderly prospective father, and men also have a suitable childbearing age. It is not good to be too early or too late.
The golden reproductive age of men
From a scientific point of view, many experimental reports in the United States, Sweden and other countries point out that at the age of 30, the sperm quality of men will reach its peak-about 70 million to 65.438+0.5 billion sperm can be produced every day (about 600 sperm can be produced every second, and hundreds of millions can be produced every day in bilateral testicles), and the sperm reconstruction process can be completed almost every three months on average.
At this time, men will be in a superior state in terms of physical strength, energy, life experience and economic conditions, and even the genetic information contained in sperm is the best, so men of this age can be called "golden men". At this time, pregnancy is also the most appropriate, and the congenital genetic material that children get from their fathers will be the best.
After the age of 30, especially after the age of 35, the number of sperm will not only decrease by 1% on average every year, but also the quality and activity will decrease, and the probability of gene mutation will increase, which may lead to some fertility crises.
Male fertility crisis
1. Male sperm quality is poor and fertility is impaired.
According to the White Paper on the Investigation of Male Sperm Quality in China in 20 12 years, about 20% of the nearly 40 million infertile people in China are caused by poor sperm quality. At present, the male sperm quality is declining at a rate of 1% every year.
2. Male sperm quality is poor, and the rate of fetal malformation increases.
There was once a paper in Nature devoted to the whole genome sequencing of parents and children, which pointed out that the number of new mutations in children came from the father's side higher than that from the mother's side.
If male sperm quality is poor, it may lead to poor embryo quality, and children may suffer from deformities and genetic diseases in the future.
Compared with 20-year-old men, the sperm count of men in their thirties and forties is at least less than 16%, and men can effectively improve their fertility in some ways, thus prolonging their childbearing age.
To improve fertility, men need to do three things well.
1. Insist on physical exercise
Although age has a great influence on fertility, the quality of sperm can be better improved by other means.
First of all, male friends should pay more attention to exercise, improve physical fitness, improve immunity and resistance, so as to improve their vitality and fertility.
Step 2 eat reasonably
If you want to improve the quality of sperm, then the diet is also more critical. Avoid all nervous foods, which are all conducive to sperm development, so as to be conducive to sperm production, such as foods rich in zinc, and protein contains vitamin C.
Learn to decompress
For male friends, if life pressure is very high, it will reduce sperm quality and may even cause sperm variation. If you want to ensure the quality of sperm and improve the fertility of male friends, men should learn to decompress themselves and avoid some negative emotions, thus affecting fertility.
