A new study has found that staying up late to watch movies or catch up on emails could affect men’s sperm count and damage their chances of fathering children.

Men trying to have a baby could increase their chances of getting their partner pregnant if they go to bed before 10.30 at night. The study also found that men with an early bedtime are almost four times more likely to have good-quality sperm.

It’s been discovered that sleep deprivation can cause the immune system to overreact and attack sperm, while going to bed too late may see couples run out of time to have sex.

Scientists asked men what time they’ve been going to bed over the past month. Those who went to bed before 10.30pm were almost four times more likely to have normal sperm than men whose bedtime was 11.30pm or later.

Professor Hans Jakob Ingerslev, co-author of the study from Aarhus University, said: “These were men who had been trying to have a baby for about two years and an early bedtime was likely to be important because it allowed them to get more sleep.

“The reasons could be psychological as sleep-deprived men suffer mores stress and that can have an impact on fertility.”

Dr Raj Mathur, a consultant gynaecologist at Manchester University NHS Foundation Trust, who was not involved in the study, said: “The study suggests men who are trying for a baby should be going to bed early and getting a decent amount of sleep.

“They should think about what is keeping them up and try to change their habits, whether it’s binge-watching Netflix or sending emails.
