Hello,

Nocturnal penile tumescence (NPT), sometimes called morning wood, is a type of random erection. The main symptom of NPT is waking up with an erect penis. NPT is a common occurrence for many boys and men.

Waking with an erect penis is a sign of healthy blood and nerve supply to the penis. Boys and men with NPT are likely to be able to maintain an erection while awake.

NPT is more common in younger men, though adult men can experience this. As men reach the ages of 40–50, natural testosterone levels begin to fall.

As this level decreases, episodes of NPT may decrease as well. On average, men experience up to five erections while they are sleeping, and each erection lasts about 30 minutes.

Many factors are thought to cause NPT. One cause is physical stimulation, which your body can sense even while you sleep.

This means your bedsheets brushing against your skin could trigger an erection.

Hormonal shifts may be the culprit, as testosterone is highest in the morning after waking.

Brain relaxation may also be a factor, as the body releases hormones to suppress erections during waking hours, but less of them during sleep.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Regards,
