A research result in the United States may be able to give more sufficient reasons for male compatriots who do not want to do housework: the electromagnetic field produced by home appliances such as vacuum vacuum cleaners will affect male fertility.
Researchers from Stanford University in the United States selected 148 volunteers.Among these people, 76 people have problems such as lack of activity, irregular shapes, and insufficient quantity of sperm, and the sperm quality of 72 people is better.
These volunteers come from all walks of life, but do not include people who have been in high temperature or chemical pollution environment for a long time, thereby excluding the possibility of volunteers being damaged by sperm damage due to external environmental influence.
According to the requirements of the researchers, volunteers carried measuring instruments with them in a day when they thought they were representative, and this instrument automatically recorded electromagnetic radiation data every 4 seconds.
Researchers have found that half of the volunteers have exceeded 0.16 Micro Tesla, and the low probability of sperm quality of these people is twice the other half of the volunteers.
Studies also show that the longer the time when it is in high -intensity magnetic field radiation, the greater the possibility of sperm quality decrease.
Researchers say that refrigerators, microwave oven hair dryers and vacuum vacuum cleaners, such as common electrical appliances equipped with motor, can generate high -frequency and high -intensity electromagnetic fields.
U.S. researchers said at the 62nd annual meeting of the American Reproductive Medicine Society held in October that mobile phones may also affect sperm quality, and the degree of influence depends on the daily use of mobile phones.
Researchers studied 364 men's information and found that the number of sperm in men who did not use mobile phones was 86 million, of which 40%were normal and 68%activity was normal.However, the average number of sperm in men's sperm per milliliter of semen with mobile phones for more than 4 hours a day is 66 million, of which 21%of which are normal and 48%activity is normal.
Researchers say that the specific reasons for the effect of mobile phones need to be further studied.
Earlier studies have shown that excessive smoking, drinking, poor diet, drug absorption, and obesity may also lead to a decline in sperm.
