Firstly, morning erections are a common occurrence and there is nothing to worry about. Most experts will tell you that an erection first thing in the morning is not be due to any kind of sexual stimulus, but a few erotic thoughts through the night could also be the reason. But why do men have this peculiar problem? Well, we tell you exactly why.
Reason #1: A man’s REM sleep cycle: In a study published in the Achieves of General Psychiatry [1] researchers found that men characteristically have about five erections every night that is linked to the REM (Rapid Eye Movement) cycle of sleep. It is believed that at this time the brain shuts down a particular pathway to prevent a person from acting out their dreams. Also known as the pathway led by the noradrenergic cells, when these pathways are shut down it leads to the increase in activity of testosterone dependent activities in the body which then leads to an erection.
Reason #2: Release of Nitric Oxide: Also tied to the REM sleep cycle, it is believed that when a man is in this stage of sleep, it triggers a cascade of events, and one of those is the release of NO or Nitric Oxide. This compound, causes smooth muscles to relax and blood vessels to dilate which in turn increases the amount of blood that flows into a man’s penis — causing an erection.
Reason #3: Higher testosterone levels in the morning: The amount of testosterone in a man’s body in the morning is far greater than any other time in the day[2]. This surge of testosterone is also one of the leading reasons for a morning erection.
Reason #4: The repair and restore activity of the body: Scientists also believe that night time or morning erections are the body’s way of maintaining, repairing and restoring the health of the penis. When a man has an erection it causes the erectile tissue of his penis (also known as the corpora cavernosa) to swell, which helps in oxygenating the tissue. It also helps prevent conditions like cavernous fibrosis (formation of thick fibres within the tissue) that can eventually lead to erectile dysfunction.
