Here is a transcript of the video: "It is a mistake to ignore morning erections. Morning erections should be present regularly. They should be constant, depending on your age—every day, every other day, or every three days—but it should happen constantly. Some episodes of morning erections should be firm; they should remain so when getting out of bed and hold for some time. The density of the penis should be high. If this does not happen, you should not ignore it. What happens during sleep? The man is in bed sleeping, the parasympathetic nervous system is activated, the blood vessels dilate, the cavernous bodies expand, and blood flows into the penis. All the blood vessels are working; testosterone and other hormone fractions are at work. If this does not happen, what does it mean? First, there is a decreased blood flow to the penis, or the outflow is too fast. Second, there is a low level of free testosterone and possibly high cortisol. The SHBG (Sex Hormone-Binding Globulin) level could be high as well. The third reason, which is very common, is chronic sleep deprivation because nocturnal erections occur during the deep sleep phase. If the deep sleep phase is disrupted, or if the sleep schedule is irregular, or the man does not get enough sleep, then nocturnal erection is impaired, and consequently, the morning erection is impaired as well. These are all important symptoms that should not be ignored. If you do not have regular morning erections, it is better to get checked."
