Staying up late to watch Netflix and reading e-mails affects the number of sperm cells for men and damages their chances of having children, investigates finds
- Men who go to bed early are almost four times more likely to get a good night's sleep
- Scientists asked men what time they had gone to bed in the course of a month
- Those who went to bed before 10.30 p.m. were nearly four times more likely to have normal sperm than men whose bedtime was 11.30 p.m. or later
Men trying to have a baby can increase their chances of making their partner pregnant if they go to bed before 10:30 am & # 39;
Men who go to bed early, have good quality semen almost four times as often, according to a study.
Scientists asked men what time they usually went to bed last month, and whether a doctor had determined that they had normal or low quality sperm.
Those who went to bed before 10.30 p.m. were nearly four times more likely to have normal sperm than men whose bedtime was at 11.30 p.m. or later.

When most men trying to start a family start working early every day, experts say that adequate sleep is essential.
Evidence suggests that sleep deprivation can cause the immune system to overreact and affect sperm, while going to bed too late can see that couples no longer have time to have sex.
Professor Hans Jakob Ingerslev, co-author of the study at the University of Aarhus, said: & # 39; These were men who had been trying to have a baby for two years and going to bed early was probably important because it offered them more sleep.
& # 39; The reasons can be psychological, because men who are sleep deprived suffer from excessive stress and can have an impact on fertility. & # 39;
Dr. Raj Mathur, a gynecologist at the NHS Foundation Trust in Manchester, who was not involved in the study, said: & The study suggests that men trying to get a baby should go to bed early and get a fair amount of sleep.
& # 39; They should think about what is in their hands and try to change their habits, whether it's watching Netflix shaking or sending emails.

& # 39; Going to bed earlier with their partner can also increase their chances of having sex, further increasing their chances of success. & # 39;
Researchers found that men who asked & # 39; asked & # 39; went to bed before 10.30 pm, 2.75 times more likely to have normal sperm than people with more & # 39; normal & # 39; bedtime between 11 p.m. and 11.29 p.m.
Sperm bank could be set up in space, research suggests
Women could be sent to space with a selection of sperm cells ready to populate other planets, researchers say, testing the effects of zero-gravity on sperm.
Frozen semen can be transported to the space to open & # 39; the opportunity to create a human sperm bank outside the earth & # 39 ;, say researchers from the Dexeus women's health center in Barcelona.
This may mean that male astronauts are being replaced by teams for all women to reproduce in space.
Dr. Montserrat Boada, of Dexeus Women & # 39; s Health in Barcelona, said: & # 39; Some studies suggest a significant decrease in the motility of human fresh sperm steel.
& # 39; But nothing has been reported about the potential effects of gravity differences on frozen human gametes, in which state they can be transported from Earth to space.
& # 39; It is not unreasonable to start thinking about the possibility of reproduction outside the earth. & # 39;
Men who slept between seven and a half and eight hours longer normally had sperm, which naturally increased their ability to have a baby.
The results suggest that they were six times more likely to have good quality sperm than those who slept less than seven hours a night on average.
The Danish study, presented as a poster at the annual conference of the European Association for Human Reproduction and Embryology (ESHRE) in Vienna, asked men how many hours of sleep they got, as opposed to the number of hours they spent in bed.
Participants in the study, who were on average 34 years old, also received a score on sleep quality based on their total answers in a questionnaire.
The sleep quality was poor, for example if they had to get up at night to use the bathroom or had trouble sleeping within half an hour.
However, this overall sleep quality score was found to be unrelated to sperm quality, which the men and their partners both reported based on their test results from a fertility clinic.
The authors state that their study was small and further research is needed.
But Dr. Christopher Barratt, professor of reproductive medicine at the University of Dundee, said: “Telling men trying to get pregnant to get more sleep is a very sensible message, although this is a small study.
& # 39; If you do not sleep enough, it influences the metabolism, which has a negative effect on the quality of the sperm.
& # 39; It's a fairly simple advice, but lack of sleep is closely related to feeling stressed and stressed men are also less likely to have sex once a day, as we recommend when trying for a baby. & # 39 ;
