The survey shows that the work that a man is engaged in may affect his fertility status, but the researchers said that such findings need further research to reach a definitive conclusion.
It has been noted that there are many reasons for male infertility, but recent research data show that some lifestyle is indispensable.
The research team of the National University of Singapore found that men engaged in engineering technology, financial analysis, corporate and computer management and teachers were more likely to be infertile than men engaged in other professions. The research results were published in the November issue of the Journal of Occupational and Environmental Medicine.
In order to find out whether men's occupation affects their fertility, the Singapore research team queried 640 men whose spouses were unable to conceive or who were undergoing infertility treatment. They screened 218 men from these men who could not find out the cause of infertility, and compared these men with 227 men whose wives were pregnant now.
The survey results show that the four kinds of professionals are easy to be infertile.
Category I: The probability of male infertility in the teaching profession is 7 times higher than that of the average male
By comparison in the form of survey paper, the questions that men need to answer include smoking, occupation, chemical and radioactive work, etc., and then they were tested for sperm.
Category 2: The probability of male infertility engaged in financial analysis is five times that of ordinary male
The survey results show that the probability of male infertility is the lowest among those engaged in service and clerical work.
Category III: The probability of infertility in engineering technology is three times that of ordinary men
The research team could not correctly explain the reasons for the difference in infertility, but they pointed out that psychological stress, high work requirements and possible electromagnetic field working environment were the main factors of male infertility.
Category 4: The probability of male infertility managed by computer is three times that of ordinary male
At present, the number of male infertility patients engaged in IT industry has increased significantly. Although there is no specific statistical data, preliminary conclusions can be drawn from the usual diagnosis. The above doctors can see that the probability of IT male infertility is high.
In addition, the probability of infertility of men who regularly smoke is three times higher than that of non-smoking men
The medical research team of the National University of Singapore, after analyzing the semen samples of men with normal fertility and infertility, reached the conclusion that smoking reduces the number of sperm.
