According to the latest research, men who drive cars professionally are more likely to experience infertility. Researchers have found that driving can cause an increase in scrotal temperature, which can have adverse effects on sperm formation in the testes.
The research team conducted experiments on 9 adult men. They fixed the thermometer on the surface of the subject's scrotum. The subjects walked first and then drove for 160 minutes. During the first 20 minutes of driving, the average temperature of the subject's scrotum increased from 34.2 ℃ to 35.5 ℃. Within the next two hours, the scrotal temperature reached as high as 36.2 ℃. The average temperature during driving is 2.2 ℃ higher than when walking.
Previous studies have found that men who drive for a living have a lower sperm count and a higher proportion of abnormal sperm. Their wives may need a longer time to conceive after marriage, but the reasons for these problems are unclear. Dr. Miochet, who led the study in France, said that the increase in scrotal temperature during driving may be one of the important reasons for the reduced fertility of professional drivers.
People already know the importance of keeping the scrotum cool, for example, two years ago Australia produced a type of "air-conditioned underwear" to prevent the scrotum from getting too hot. In fact, the size and thickness of the inner and outer pants have a more important impact on the temperature of the scrotum, and drivers should pay attention to it.
