Researchers at University of Southern Denmark have found that disturbed sleep among young men may affect their ability to produce sperms with their sperms counts being as much as a quarter lower than those who slept more.
The researchers conducted their study on a group of 950 men aged around 18 years old, asking them to fill out a questionnaire and took sperm samples.
On comparing their responses with their sperm counts, the researchers found that those who had trouble sleeping for at least six hours every night had lower sperm counts compared to those who slept more than six hours. The researchers suggested that lack of sleep interfered with the body's ability to produce sperms. The study has been published in the American Journal of Epidemiology.
"Men with a high level of sleep disturbance had a 29 percent lower adjusted sperm concentration. This appears to be the first study to find associations between sleep disturbances and semen quality", lead researcher Tina Kold Jensen said.
