To create penile erections, your hormones, nerves, blood vessels, and muscles all work together. Erections happen from childhood through old age, but have you ever noticed having the so-called penile tumescence or night-time erections?
Night erections typically occur three to five times throughout the night. While it is fairly common among men, researchers continue to probe on why they happen.
Here are some possible reasons why night erections occur:
- Erotic fantasies – It could be simple: you’re having sexual dreams, which is why you have a night erection. Your penis may also become erect in anticipation of sex while you’re still in the world of dreams. As a result, a wet dream – a night erection involuntarily creating semen ejaculation – takes place. If you’re interested to know, this usually occurs during rapid eye movement or REM, the phase of deep sleep.
- Release of nitrous oxide – Did you know that blood vessels may enlarge when nitrous oxide is released? This occurrence allows the blood flow to you’re the tissue of your penis, creating an erection. Different areas of your body produce nitrous oxide naturally, and it serves as a crucial presence in the artery walls. NO therefore aids sleep, relaxation, and penis enlargement.
- Highly oxygenated penile tissues – Tissues of your genitals receive large amounts of oxygen when your penis becomes erect, and it is known that oxygen-rich blood is an important part of maintaining your ability to have an erection. At night, the oxygenated tissues cause your penis to swell with blood.
- Bladder control failure – Night erections may also occur due to failure in bladder control. When your bladder swells to capacity when you sleep, urine also fills your penis, and consequently your urine makes your penis erect. When you sleep, it is believed that you possess no control over your system, and this loss of physical and hormonal control also fails to control erectile ability.
