A study of Spain shows that even in young men, sperm concentration decreases at an average per year on average.In the long run, the sperm level will be reached soon.
In this new study, researchers at the University of Murcus in Spain compared the results collected from 273 men from 2001 to 2011.These volunteers are between 18 and 23 years old and live in the town of Almeia near Murcian.They compared these results with the samples collected from 215 Murcian university students 10 years later.These researchers ensure that the two sample groups have the same age and similar characteristics.They found that compared to men living in Almeia, the sperm number of volunteers living in Murcia was significantly reduced.
A French study carried out in December 2012 showed that sperm numbers and quality have fallen sharply since the 1990s.Researchers believe that this trend and diet, lifestyle, chemicals used for transgender or even tight underwear.From 1989 to 2005, the average sperm number of 26,000 men participated in such a study dropped by one -third, which increased the risk of infertility.In addition, the number of health sperm also decreases at a similar proportion.
This research is very important because it has 26,600 men's participation, which may be the largest research sample in the world.These discoveries also confirmed that the number of sperm in many countries in the world has declined over the past 20 years.Researchers said that the decline trend has been gradually carried out in the past 17 years, indicating that the problem is still on.A well -known expert in Britain said that the decrease in sperm number will inevitably affect men's fertility, and it is necessary to use research to find out the reason.
"Optimize" sperm quality nine tricks
1. Participate in exercise.
Studies have shown that the excessive obesity of men's body will cause the temperature at the groin to rise and damage the growth of sperm, which will lead to infertility.Therefore, weight control can improve the quality of sperm within the standard range.However, the intensity of exercise should be moderate, and severe exercise, such as marathon and long -distance cycling, will still increase the temperature of the testicles and destroy the cool environment required for sperm growth.Cycling will also cause the fragile testes to be dangerous. Therefore, it is recommended to wear shorts with pads when cycling and choose a bicycle with good shock absorption.
2. Go to the sauna and steam bathroom.
High -temperature steaming bath directly hurts the sperm and also suppress sperm production.
3. Quit smoking.
Data show that 44%believe that smoking is the most important factor in the decline in the number of sperm, so quitting is imperative.
4. Drink in moderation.
Drinking a large amount of alcohol can cause sperm quality to decrease. Men should strictly follow the recommended amount of women's halves in strict accordance with 14 & mdash; 28 standard cups (including alcohol 8 & mdash; 9 grams).
5. No.
Anesthesia, drugs, etc. are also very harmful to sperm, and it will continue for a long time.
6. Relax.
Excessive mental stress also has a negative impact on the growth of sperm.Therefore, men should do something that can relax themselves, such as walking, bathing, etc., and then enjoy sexual life.
7. Put your mobile phone in a pocket.
Put your mobile phone in pants pocket, laptop on your knees, and wearing tight pants to increase the temperature of the scrotum and harm the sperm, so you should put your phone in a jacket pocket.
8. Eat more green vegetables.
Green vegetables contain ingredients such as vitamin C, vitamin E, zinc, selenium, etc. conducive to sperm growth.Nuts and fish are rich in Omega 3 fatty acids, which should also be eaten more, which is conducive to sperm cell growth.
9. Frequent medical examinations.
Bacterial infection is also an important factor in male infertility. He should often go to the physician and receive related examinations of chlamydia and prostate.
