Under the correct circumstances, there are a lot of sperm, and the number is staggering. If you are not careful, you will be [caught] and [killed].
However, sperm is also very fragile. Legend has it that smoking, drinking, environmental pollution, work and psychological pressure, obesity, aging, even drinking cola and coffee can affect the quantity and quality of sperm, and even cause male infertility.
Today, let’s see if those spermicidal legends are true.
Six Legends of Spermicide
1. Smog Kills Sperm?
Yes.
Persistent environmental pollutants (POPs) contribute to the decline in male reproductive capacity. Such pollutants include household and industrial emissions, automobile exhaust, sewage and pesticides. Severe smog, especially PM2.5, can also affect people’s reproductive capacity.
2. Drinking can kill sperm?
Yes.
Alcohol not only affects liver function, but also affects your [upper body], causing memory loss, and also affects your [lower body] and damages sperm quality.
3. Smoking can kill sperm?
Yes.
Smoking will not only reduce the number of sperm and slow down their movement, but also cause sperm deformation and DNA damage. Some studies have shown that the number of sperm in men who smoke frequently is 22% less than that in men who do not smoke.
The greater the amount of smoking, the less the number of sperm, the higher the malformation rate of sperm and the lower the motility of sperm.
4. High temperature can kill sperm?
Be vigilant. To be precise, the testicles should be afraid of high temperature.
High temperature environment, varicocele, sperm quality will be affected, sperm concentration in semen will also decrease. Therefore, to avoid wearing tight pants (underpants), avoid long-term sauna and work in high temperature environment.
5. Can Coke Kill Sperm?
False.
There was once a [secret recipe] circulating among the people, that is, after sex, one does not need to take emergency contraceptives, but rinses them with cola afterwards.
However, this [secret recipe] has long been rejected by clinical experiments: [various soft drinks have been used to study sperm motility. Compared with the control group that was not washed with soft drinks, sperm still has 70% normal speed and motility. Among them, although cola has the greatest spermicidal effect, the spermicidal effect can be ignored compared with spermicidal products.]
6. Can coffee kill sperm?
No evidence.
It has long been suspected that drinking coffee in men will affect the DNA of sperm and lead to a decline in reproductive ability. However, unfortunately, so far, clinical epidemiological studies have found no evidence that drinking coffee in men will lead to a decline in reproductive ability.
Always suspected, never proved.
The horse runs, the dance dances and the coffee drinks.
Sperm is abundant, and sperm is also very fragile.
Human beings reproduce both sexes, but men and women are unbalanced: many sperm, few eggs, very small sperm and very large eggs.
Every time they have sex, men can excrete about 20-60 million sperm, while women usually only excrete one egg per month.
The whole cycle of male sperm from development to maturity is about 64 days.
Although the cycle of sperm regeneration is very long, fortunately, the number of sperm produced in human beings within 24 hours per gram of testis tissue is large, about 3-7 million, and the maturation of sperm is continuous and uninterrupted.
Among the many factors causing infertility, the proportion of male factors is about 10% ~ 15%, and some literatures think that this proportion is even higher, up to 20% ~ 30%.
Among the factors of male infertility, oligospermia, asthenospermia and azoospermia are the most common.
According to domestic and foreign literature reports, in the past few decades, the number and quality of male sperm have decreased significantly. The total number of sperm has decreased by about 50%, and continues to decline at a rate of 1% per year.
There are many reasons for the decline in sperm quantity and quality, mainly related to environment and living habits.
There are a lot of sperm, and sperm is also very fragile. There are many legends of spermicidal, but fortunately there is no need to quit cola.
