Breeding a child is a kind of instinct for human beings.Every family and couple want to have a healthy, smart and beautiful child.This is eugenics.Eugenics is undoubtedly the common responsibility of both couples.So, as a male, how should "prospective dad" go according to the scientific method, improve the innate quality of normal fetuses and prevent the birth of the disabled, and ensure that the quality of the descendants is excellent?Guarantee "good breeds".
As the saying goes: "Planting melon, soy beans." This is the genetic phenomenon of creatures.If you want to be eugenics, you must have an excellent "seed" first.For men, this "seed" is a sperm with a large number and good quality.
Refusing tobacco and alcohol hazards
According to research, in male semen that smoke for more than one year, the deformed rate of sperm is more than 20%, and the longer the smoking history, the more the number of deformities sperm.For more than 30 smokers a day, the survival rate of its sperm is only 40%.Alcohol is a kind of gonad toxin. Drinking a lot of alcohol for many years will leave a regret that it is difficult to recover for men's sexual function. After the germ cells are "drunk" by alcohol, they will randomly produce some sub -sperm.Once these "disabled" sperm are combined with eggs, they must have deformed fetuses.
Keep the scrotum suitable for temperature
Sperm is particularly sensitive to the high temperature environment. According to clinical statistics, a considerable part of the men's infertility is caused by the testicular temperature higher than the normal temperature.In general, when the temperature is higher than the normal temperature of 2 ℃ ～ 3 ℃, the sperm cannot survive.
Avoid body obesity
Male obesity will affect the development of reproductive systems such as testicles and penis.Its pathogenesis is: adipose tissue has the characteristics of transformingrogestyls into estrogen, reduces male androgens in men, increases estrogen relatively, hinders sperm production and affects sperm quality.Obesity can also induce hypertension and diabetes, which can cause such diseases.
