Why do boys have their bottoms down when they wake up in the morning?

When men wake up in the morning, they notice that their penis is hard. This symptom is related to the change of hormones in the body, which makes many men feel very embarrassed and afraid to show this situation in front of their relatives. So, why do boys have hard penises when they wake up in the morning? Let's discuss the explanation below. I hope that men who have this normal situation but feel hesitant can understand it.

Why do boys have hard penises when they wake up in the morning? This is because of morning erections. In the morning, the growth hormones in men's bodies are more abundant, especially testosterone. Once the growth hormones are abundant, they will immediately cause nerve excitement and capillary dilation, which makes it easy to have morning erections.

Morning erection is a normal physiological phenomenon. It means that the penis will naturally become hard between 4 and 7 a.m. without being affected by external stimulation, sexual excitement, psychological disorders, etc. The most typical manifestation is that the penis is hard when you wake up in the morning. There are many reasons for morning erection, which may be due to bladder retention at night, or due to the influence of female hormones in the body. In addition, the reflex function of the human body's internal organs can also cause morning erection. Morning erection has no direct relationship with men's sexual function.

The reason why men get an erection when they wake up in the morning may have to do with the fact that we usually wake up from REM sleep. Testosterone is at its highest level in the morning, and this substance has also been shown to increase the frequency of erections at night. Interestingly, biologists have not found that male hormones have a significant impact on erections caused by visual erotic stimulation or imagination. This is because these erections are mainly driven by the "reward effect" of the human brain that secretes dopamine.
