One more reason why you should get enough sleep. Researchers from Denmark found that lack of sleep can lower testosterone levels and reduced sperm count. This was due to the size of the testicles are shrinking, especially in men who are sleep deprived.
In an era of fast-growing industries like the last ten years, the number decreased sperm join. The decline may be due to an unhealthy lifestyle such as diet and lack of moving on.
In a study conducted by a team from the University of Southern Denmark, the researchers conducted a survey of 1,000 men, average age 20 years. They asked participants about the schedule, disorders, and sleep habits of participants. The researchers also take measurements of testicular size and sperm count. In addition, the quality of sperm analyzed.
Men with sleep disorders such as insomnia, like staying up late, did not have a definite schedule of sleeping through the night, and often wake up recorded a decline in sperm count by 29 percent. They are also reported to have about 1.6 percent of sperm defects and testicular size smaller than men who get enough sleep.
Theory associated with unhealthy lifestyles, the researchers acknowledge that men with poor sleep quality is also usually an unhealthy lifestyle than those who have a good quality sleep.
The researchers said that men who sleep less are more likely to be overweight, drink more alcohol and smoke more than those who get enough sleep.
The study, published in the American Journal of Epidemiology has not been able to decide, whether the lack of sleep or unhealthy lifestyles that lead to decreased quality and quantity of sperm. The researchers said that further studies need to decide it.
