The answer is yes, men who stay up late for a long time will have reduced sexual performance. Modern medical research confirms the importance of quality sleep in maintaining men’s sexuality. 1, from the physiological point of view, the night erection is actually the process of the penis filling up the sexual organ by increasing the perfusion of oxygenated blood in a stretching manner. In other words, this is a kind of self-charging of men’s sexual organs, reserve sexual energy to facilitate the process of fighting again. Therefore, staying up late for a long time is actually an artificial interference with this self-recovery process. In the long run, it is bound to directly cause a decline in sexual function. This decline is not supplemented by daytime sleep. 2, in addition to stay up late for a long time, will cause endocrine dysfunction, the body’s immune system decline, etc., will affect sexual function. A scholar has done a large number of surveys and found that men who have had enough sleep to get an erection and hold on to it for a longer time than men who have not had enough sleep for a long time. So in order to keep your male masculinity long, please do not stay up late and make sure you go to sleep before 11:00. No matter how busy you are, do everything you can to get a good night’s sleep and give your nocturnal erections plenty of time and opportunity. For the sake of your “sexual” well-being. Please cherish the time that God has given you to sleep and rest.
