What causes morning erections?

I believe that every man has encountered such a situation, that is, in the morning, he will obviously feel his penis erection, and it happens without any stimulation. This makes many men feel very curious, what is the reason why men get hard in the morning?

In addition to external stimulation, the penis of a normal man can also become erect due to the reflex function of internal organs.

The most obvious is the common penis erection before waking up in the morning. This is a normal physiological condition, medically known as morning erection.

The reasons why the male penis becomes hard in the morning are: first, the concentration of testosterone in the male's blood reaches its highest value in the morning, which has the effect of stimulating penis erection; second, the frequency of urination is relatively reduced at night, urine increases blood flow to the bladder, and the pressure in the bladder increases. In addition, there are some other inducements, such as sexual dreams and some sleeping postures, the stimulation of bedding, etc., which can also make the male penis reflexively hard.

The exact mechanism of the penis getting hard in the morning has not been scientifically studied. Doctors sometimes need to use this as a reference when diagnosing changes in male sexual function, but it is not the only indicator of male sexual dysfunction. There are individual differences in the morning erection of the penis, so there is no need to generalize, otherwise it will be stressful and harmful.

It is normal for a man's penis to be hard at night, and men don't need to worry too much. If you think there are other problems with your penis, don't be afraid to go to the hospital, but you should take the initiative to ask the doctor to check it. If you are not sick, it's good. If you are sick, it's no big deal to take the initiative to treat it.
