Healthy and wise might not be the sole advantages of early to bed and early to rise. Men who go to sleep before 10:30 pm are nearly four times more likely to have normal sperm count than men who call it a night at 11.30 pm or after. This is according to a new study that looked at sleep patterns of approximately 100 male volunteers who had been attending fertility clinics in Denmark.
Researchers Aarhus University, Denmark, also found men who went to bed early before 10.30 pm were 2.75 times more likely to have a normal sperm count than those using a more regular bedtime between 11 pm and 11.29pm, according to the Daily Mail. The researchers asked the men what time they’d typically gone to bed within the last month, and then a physician determined if they had regular or a low sperm count.
Professor Hans Jakob Ingerslev, the co-author of this analysis from Aarhus University, noted that these were guys who were looking to father baby for around two decades and an early bedtime was likely to be significant because it enabled them to get more sleep. The reasons could be emotional as sleep-deprived men suffer more anxiety which can affect fertility.
Dr Raj Mathur, a consultant gynaecologist at Manchester University NHS Foundation Trust, who wasn’t involved in the study, told Daily Mail that the analysis suggests that men that are looking to father a baby should be going to bed early and getting a fair amount of sleep. They ought to think about what is keeping them up and try to change their habits, whether it’s binge-watching Netflix or sending emails. Going to bed earlier with their spouse may also increase their chance for sex, improving their odds of success further.
