Nocturnal penile tumescence is a spontaneous erection of the penis during sleep or when waking up. Along with nocturnal clitoral tumescence , it is also known as sleep-related erection , morning glory or morning wood . [1] Men without physiological erectile dysfunction or severe depression [2] experience nocturnal penile tumescence, usually three to five times during a period of sleep, typically during rapid eye movement sleep . [3] Nocturnal penile tumescence is believed to contribute to penile health. [4]

The cause of nocturnal penile tumescence is not known with certainty. 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. [5] 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. 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. [6] Suh et al. (2003) recognizes that in particular the spinal regulation of the cervical cord is critical for nocturnal erectile activity. [7]

The nerves that control one’s ability to have a reflex erection are located in the sacral nerves (S2-S4) of the spinal cord . [8] Evidence supporting the possibility that a full bladder can stimulate an erection has existed for some time and is characterized as a 'reflex erection'. [9] A full bladder is known to mildly stimulate nerves in the same region.
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 [ citation needed ] . However, given females have a similar phenomenon called nocturnal clitoral tumescence , prevention of nocturnal enuresis (bed-wetting) is not likely a sole supporting cause. [10]

In a study published in 1972, [11] during puberty, the average tumescence time per night was 159 min; average REM sleep time was 137 min. Average simultaneous REM sleep and penile tumescence per night was 102 min. Study subjects averaged 6.85 tumescence episodes/night, and, of these, 5.15 occurred during a REM sleep period. 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 had at least four REM periods per night and at least three tumescence episodes.

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. In contrast to younger age groups, the majority of those above age 60 did not have full sleep erections even though they and their partners reported regular intercourse. [12]

Unlike physiological penile tumescence, sleep-related painful erections (SRPE) and stuttering priapism (SP) are much rarer pathological erections, resulting in poor sleep and daytime tiredness, and long term cardiovascular morbidity. [13] SRPE, though also occur predominantly during REM sleep, without an apparent underlying illness are painful and thus interrupt sleep. On the contrary, stuttering priapism can occur spontaneously at any time of the day, but more commonly so during REM sleep. SP is a subtype of ischemic priapism that is characterized by recurrent, self-limiting, painful erections that often require maneuvers (compression, cold packs or a cold shower, voiding, or exercise, etc.) to aid detumescence. In ischemic priapism, most of the penis is hard; however, the glans penis is not. Much rarer priapism is secondary to blunt trauma to the perineum or penis, with laceration of the cavernous artery, which can generate an arterial-lacunar fistula resulting in a high blood flow state, hence the tumescence. Tumescence lasting for more than four hours is a medical emergency. [14]

The existence and predictability of nocturnal tumescence is used by sexual health practitioners to ascertain whether a given case of erectile dysfunction is psychological or physiological in origin. [3] A patient presenting with erectile dysfunction is fitted with an elastic device to wear around his penis during sleep; the device detects changes in girth and relays the information to a computer for later analysis. If nocturnal tumescence is detected, then the erectile dysfunction is presumed to be due to a psychosomatic illness such as sexual anxiety; if not, then it is presumed to be due to a physiological cause. [3]

Regularly, those who experience erectile dysfunction are given a nocturnal penile tumescence (NPT) test, usually over a three-day period. Such a test detects the presence of an erection occurring during sleep using either:

The goal of nocturnal penile tumescence testing is to determine whether one can experience an erection while sleeping after reporting that they are unable to experience an erection while awake. On average, one has 3–5 episodes of NPT each night, and each episode lasts 30–60 minutes, although the duration is reduced with advanced age. [15] If one does obtain an erection while sleeping, but cannot obtain one while awake, a psychological cause or a medication side effect is usually suspected. Otherwise, if one does not obtain an erection in either state, a physiological cause is usually suspected.

How to Deal with Stretch Marks on the Penis: Causes and Treatment Measures
Almost everyone feels better after a good night’s sleep, and many men report that feeling tired or fatigued can sometimes impact their sexual performance, but is there a reason for lack of sleep to impact penis health? Several studies have indicated that the answer is affirmative; now some animal studies are looking more closely into specific reasons why penis health might have a connection to sleep or the lack thereof.
One such study is in the January 2019 edition of the Journal of Sexual Medicine . Entitled “Impact of Sleep Deprivation on the Hypothalmic-Pituitary-Gonadal Axis and Erectile Tissue,” it used male rats as its subjects. (Animal studies are typically used in order to test initial hypotheses or better understanding learnings from basic science.)
A total of 56 rats were used, but they were treated in segments. The first 16 rats were deprived of sleep for 72 continuous hours (three days); a second group of 16 rats were chosen as controls, and their sleep patterns were not interfered with at all. Various markers associated with hypogonadism were measured. (Hypogonadism is the term used to describe a situation in which the body doesn’t produce sufficient sex hormones. Hypogonadism may result due to a problem with the gonads themselves, or because the hypothalamus and/or the pituitary glands, which control the gonads, aren’t working.)
In addition, another 24 rats were divided into 3 groups of 8. One group was a control group; one group was sleep deprived and one group was sleep deprived and was also given testosterone supplementation.
Essentially, the study showed that sleep deprivation in rates did indeed bring about hypogonadism. Those rats in the control group had normal markers; those who were sleep deprived were severely lacking in testosterone. (The group that was both sleep deprived and given testosterone supplementation did have testosterone levels similar to the control group.) The lack of sleep also dampened the production of nitric oxide, which is needed to keep penile blood vessels expanded during sexual phases.
These results back up results from earlier studies that looked at sleep deprivation and sexual issues in rats. One, “Effect of sleep deprivation on the male reproductive system in rats,” found that lack of sleep greatly decreased sperm motility (that is, how well and quickly sperm move and swim) in rats.
All of these studies are looking at actual sleep deprivation – going without sleep for 3 days. Clearly, such results would likely not occur in the same way in a subject who gets sleep, but not enough – say, only 3 or 4 hours of sleep each night. But the studies do suggest that cumulatively and over time, getting too little sleep can result in decreased testosterone and in subsequent penis health issues.
Men who get insufficient sleep should take steps to correct this issue. In some cases, there are some simple lifestyle changes that can help such as:
– Limiting intake of caffeine in the latter part of the day
– Avoiding computer use near bedtime
– Making the sleep space inviting (appropriate temperature, sufficient darkness, comfortable mattress, etc.)
– Being consistent with bedtimes and wake-up times
– Getting an appropriate amount of exercise during the day
In some cases, a person may need the help of a medical professional in assessing sleep issues and determining possible solutions.
Lack of sleep is not the only cause of penis health issues, so to be better prepared, a man should regularly apply a first class penis health creme (health professionals recommend Man 1 Man Oil , which is clinically proven mild and safe for skin) to his manhood. The most effective cremes will include L-arginine, an amino acid which helps produce nitric oxide, which in turns keeps penile blood vessels open. The crème should also include moisturizers such as shea butter and vitamin E to keep penis skin healthy; itchy penis skin can disrupt a good night’s sleep.

This is what happens to your penis when you sleep with boxers on

Medics have presented a strong case for going commando
In case there were any doubt, sleep is amazing.
While we're getting our shut-eye, our bodies are using this crucial time to restore and rejuvenate themselves.
During the night, incredible physical feats are occurring - muscle is growing, tissue is being repaired, and our hormones are being synthesized.
On the downside, if you're a man, you may also be basically cooking your swimmers and damaging your fertility.
In a strong case for going commando of a night, Dr Brian Steixner, Director of the Institute for Men’s Health at Jersey Urology Group in the US, advised men against sleeping in boxers or briefs.
Dr Steixner is also the ray of sunshine who told us what the ageing process does to the penis .
So what's so bad about boxers or briefs?
Urging men to go commando in bed for the good of their health, Dr Steixner explained the quality of sperm can be affected by men's crotches overheating at night.
He said, as The Sun reports, "Your nether regions need to be just the right temperature in order to optimise sperm production."
Not only that, but there's a risk of infection too.
"More bacteria makes for a higher likelihood that any chafed or irritated skin down there becomes infected."
This is not the first time the benefits of sleeping naked have been brought to our attention.
The summer's short-lived heat wave may seem like a dim and distant memory, but as a result of it, we learned how going commando in bed keeps our cortisol in check, boosts the metabolism and may make us feel more fresh in the morning.
It just doesn't seem that appealing while we're in the freezing depths of winter.

Yes! A woman that really likes this, and I know you know what you are doing because perpendicular scissors is absolutely correct. I do this twice a week, but have never been able to cum. Sometimes it is extremely tight, and I stay hard for hours. At 53, that's not bad.

The best way to stay in side her is to hold of cumming. Stay hard by going very slow. she will wonder what the hell Your up to but she will catch on soon enough. You can stay hard with a lot of practice. Dr, Phil
