In another study of healthy older people published in 1988, frequency and duration of nocturnal penile tumescence decreased progressively with age independent of variations in sleep. Study subjects had at least four REM periods per night and at least three tumescence episodes. Tumescence episodes during REM averaged 30.8 min in duration, whereas episodes which occurred when no REM was present averaged 11.75 min. Study subjects averaged 6.85 tumescence episodes/night, and, of these, 5.15 occurred during a REM sleep period. Average simultaneous REM sleep and penile tumescence per night was 102 min. In a study published in 1972, during puberty, the average tumescence time per night was 159 min average REM sleep time was 137 min. However, given females have a similar phenomenon called nocturnal clitoral tumescence, prevention of nocturnal enuresis (bed-wetting) is not likely a sole supporting cause.

The possibility of a full bladder causing an erection, especially during sleep, is perhaps further supported by the beneficial physiological effect of an erection inhibiting urination, thereby helping to avoid nocturnal enuresis. A full bladder is known to mildly stimulate nerves in the same region. Evidence supporting the possibility that a full bladder can stimulate an erection has existed for some time and is characterized as a 'reflex erection'. The nerves that control one's ability to have a reflex erection are located in the sacral nerves (S2-S4) of the spinal cord. (2003) recognizes that in particular the spinal regulation of the cervical cord is critical for nocturnal erectile activity. Bancroft (2005) hypothesizes that the noradrenergic neurons of the locus ceruleus in the brain are perpetually inhibitory to penile erection, and that the cessation of their discharge that occurs during rapid eye movement sleep may allow testosterone-related excitatory actions to manifest as nocturnal penile tumescence.

Parasympathetic branches extend from the sacral plexus of the spinal nerves into the arteries supplying the erectile tissue upon stimulation, these nerve branches release acetylcholine, which in turn causes release of nitric oxide from endothelial cells in the trabecular arteries, that eventually causes tumescence. In a wakeful state, in the presence of mechanical stimulation with or without an arousal, erection is initiated by the parasympathetic division of the autonomic nervous system with minimal input from the central nervous system. The cause of nocturnal penile tumescence is not known with certainty.

Nocturnal penile tumescence is believed to contribute to penile health. (Colloquially, the term morning wood (or less commonly, morning glory) is also used, although this is more commonly used to refer specifically to an erection beginning during sleep and persisting into the period just after waking.) Men without physiological erectile dysfunction or severe depression experience nocturnal penile tumescence, usually three to five times during a period of sleep, typically during rapid eye movement sleep. Along with nocturnal clitoral tumescence, it is also known as sleep-related erection.

Nocturnal penile tumescence is a spontaneous erection of the penis during sleep or when waking up. Spontaneous erection during or after sleep
