To increase their chances of becoming a father, men should go to bed before 22:30, according to a Danish study. A lack of sleep would have a damaging effect on Fertility, say the researchers.
Sleep earlier to improve fertility. This seems to be the case, according to researchers at the University of Aarhus (Denmark). They have shown that the early birds are four times more likely to have “good quality” semen than those who go to bed later. Their results were presented at the annual conference of the European Society of Human Reproduction and Embryology (ESHRE) which was held from 23 to 26 June in Vienna (Austria). They are relayed by the British newspaper The Independent.
The scientists studied the sleep patterns of a hundred male volunteers attending Danish fertility clinics. In total, 48 had “good quality” semen, while 56 had “poor quality” semen. And finally, men who went to bed before 10:30 pm were four times more likely to have healthy sperm than night owls. The figure was 2.75 times compared to those who went to bed at a “normal time”, that is to say between 10:30 and 11:30.
But it seems that the lack of sleep is all the more prejudicial. Men who slept less than seven hours a night were six times more likely to have “poor quality” semen. Because nights play a key role in the production of hormones. The stress associated with sleep deprivation can lead to inflammation, a reaction of the immune system and thus an “attack” on the spermatozoa. The reasons could also be “psychological, because sleep-deprived men suffer from lifestyle stress, which can have an impact on fertility,” said Professor Hans Jakob Ingerslev, co-author of the study.
If it has not been published yet, it can provide advice to individuals who have difficulty conceiving, said independent experts present at the conference. Male members “should think about what keeps them awake and try to change their habits, whether it’s binge-watching Netflix or sending emails at night,” said Dr. Raj Mathur, consultant in gynecology at Manchester University NHS Foundation Trust interviewed by The Independent, going to bed early with one’s partner can also increase the chances of having sex, improving their chances of success.”
