There is a saying on the Internet that the larger the men's sperm quality, the relatively worse.Some netizens listed the research situation of the University of Aberdeen in the United Kingdom. The research team analyzed the sperm of more than 5,000 adult men in Scotland.Divide these men into different groups.BMI is normal weight between 20 & mdash; 25, 25 & mdash; 29 is overweight, and 30 or above is obese.
The results showed that men with BMI in 20 & mdash; 25 have a higher level of normal sperm, while overweight and obese people not only have a small amount of semen (sperm quantity), but also the number of normal sperm is not large.Obesity men have less than 60%of the less sperm, and the chance of abnormal sperm is also more than 40%.The overweight is about the same situation as the obese man.Researchers excluded other factors that may affect sperm count, such as smoking, drinking, abuse of drugs, and age, which confirmed that obesity did affect sperm count and sperm quality.
The saying on the Internet is that the rumors of netizens are indeed scientific basis.
Under the same case, obese men's sperm quality is poor than that of physical fitness men
Experts said that for men, the generation of sperm is like a factory processing a product.Sperm materials are protein, sugar, nucleic acid, etc., and testosterone is a additive that must be added during processing.The testosterone is mainly supported by the cell secretion on the sperm tube. The testosterone secreted by men has a range, which is a relatively fixed range."Testosterone will flow as the whole body flows, and the greater the size of a person, the larger the testosterone concentration in the blood at the level of the same testosterone hormone.
In addition, human temperature also has a great impact on sperm production.The normal body temperature of a person is about 37 ° C, and the best temperature generated by sperm is 34 ° C. The male genitals are exposed outside the body, which is conducive to sperm production.Experiments have proved that every 1 ° C rose, the survival rate of sperm decreased by 15%. "Medically, there are high temperatures to kill Xiongxiong." Experts said that obese men have more fat, which is not conducive to its heat distribution. Their temperature is better than normal than normal than normal.People are higher.The high temperature of the scrotum part will directly affect the sperm ability of the testicles, causing sperm production to reduce; at the same time, the sperm quality will also be affected.
Scientifically eat a strong "seed"
Nicotine in tobacco has the effect of lowering sex hormone secretion and killing sperm.Long -term alcoholism can also cause damage to the sperm cells of the testicles and affect sperm production.He suggested that unprecedented men are best to stay away from tobacco and alcohol. In addition, celery and cottonseed oil also have fine substances, and men who are not fertilized are also best to eat.In addition, some foods can also help sperm, but experts do not agree with everyone to eat male health products.
Seafood: contain a variety of unsaturated acids, which can block the human body's response to cigarettes and enhance the body's immunity; zinc and selenium content is also high, which is conducive to sperm production.
Lysine: lysine is a necessary component for sperm.Foods with high Fenate are: catfish, loach, squid, yam, tofu skin, etc.
Zinc: Trace element zinc is known as "husband and wife harmonious". Men lack zinc and reduce sexual desire and sexual function. The number of sperm decreases by 30%to 40%, and even makes people lose fertility.Zinc is mainly existing in seafood and animal organs.
Nucleic acid: Nucleic acid is the core material for dominating life activities. It is not only the basis of protein synthesis, but also provides genetic information, which plays a key role in the growth, development, reproduction, and genetic activities such as human body growth, development, reproduction, and genetic activities.Foods rich in nuclear acids include beef, animal liver and kidney, shrimp, oysters, mushrooms, nuts, etc.
Vitamin E: Vitamin E is a favorable sperm generation and improvement of sperm.It mainly exists in egg yolk, beans, peanuts and vegetable oils.
