Talk:Nocturnal penile tumescence

Urination?
Is there any corrilation with morning wood and the urge to urniate? I thought I remembered something from anatomy and phys years ago in highschool about how an errection somehow inhibits the passage of urine, and therefore sometimes if one has a full bladder the body will get an erection to prevent urination.

The prostate gland also achieves tumescence during an erection. The urge and capability to urinate is lowered because the urethra is squeezed by the swollen prostate. It is still possible to urinate with an erection but lean forward a lot and try not to hit yourself in the face... —Preceding unsigned comment added by 71.139.185.218 (talk) 08:31, 27 December 2007 (UTC)
 * I don't think it is the main cause. IF people have urinary catheters, where the urine flows into a bag during the night, they may still have morning wood. But they always have empty bladders. This is a really good control and I am baffled that this speculative idea has not had people with bladder catheters as control, as they have empty bladders all of the time. 212.97.251.178 (talk) 15:10, 7 July 2024 (UTC)

Does the photograph add relevant content?
I submit that the photograph should be removed as not adding relevent content to the entry. Are there any objections? Will someone post reasoning why the photograph should be part of the entry?

 * I'm not sure. In general images are good, and Wikipedia does have a content disclaimer that explicitly notes Wikipedia's use of images depicting human anatomy that some might find objectionable or offensive; but even so, I'm not generally a fan of such images except when it seems that they contribute quite a bit to the article's informative content, and it doesn't seem that this image does so for this article (especially since you can't actually tell from the picture that the tumescent penis belongs to a sleeping person). —RuakhTALK 20:08, 29 December 2006 (UTC)


 * O.K., since no one has posted in defense of the image, I've commented it out. —RuakhTALK 18:54, 5 January 2007 (UTC)

Anybody got a source?
Anybody got a source that connects NPT with the cooler temperatures one experiences at night? Gotta be Anon (talk) 10:44, 15 February 2008 (UTC)

This isn't a "List of euphemisms for NPT"
References to "colloquialisms" were way out of place. I deleted them as unencyclopedic. Sure, the euphemisms are fun, but this isn't them place for them I think.

Agree, they are an open invitation. Anyone needing to look up these will find plenty of references elsewhere. Danmux (talk) 23:09, 30 June 2012 (UTC)

NPT as evidence against physiologically caused ED
WP:Reference_desk/Archives/Science/2011 November 20 questions the uncited assertion in this article that the presence of NPT in ED patients indicates a psychosomatic cause, and provides a reference which contradicts that. I will try to find some more references on this. -- 110.49.227.5 (talk) 03:32, 1 January 2012 (UTC)

Requested move

The result of the move request was: not moved. Favonian (talk) 10:32, 18 February 2012 (UTC)

Nocturnal penile tumescence → Morning wood – Per WP:JARGON, terms should be readily accessibly to all. I doutb anybody uses "Nocturnal penile tumescence" in real life. Therefore per wikipedia policy it should be changed to "morning wood". Pass a Method  talk  22:40, 10 February 2012 (UTC)
 * Support per WP:COMMONNAME. Powers T 19:34, 11 February 2012 (UTC)
 * I do note, however, that Morning wood was the location of the disambiguation page until PassaMethod moved it to Morning wood (disambiguation) coincident with this move request. It would have been better to consider those two moves together as one request.  If this move is rejected, we should consider whether or not this article is the actual primary topic.  Powers T 19:36, 11 February 2012 (UTC)


 * Oppose – none of the article's cited sources even mention that slang term. And moved the disambig page back, too.  Dicklyon (talk) 22:07, 12 February 2012 (UTC)


 * Oppose – not only for the article title, but also for the inclusion of the two slang terms "morning wood" and "morning glory" in the lede unless it can be demonstrated that these two terms are particularly prevalent, including among WP:ENGVAR. Apparently these two terms are relative neologisms, and I understand that an older generation of G.I.s would much more readily recognize "piss hard-on". Urbandictionary.com includes a number of such slang terms for the phenomenon. Ref This isn't a "List of euphemisms for NPT", above.
 * This article is a classic example of what WP:REDIRECT is for. In any event, Dicklyon's point is dispositive as to the article title. Milkunderwood (talk) 07:26, 14 February 2012 (UTC)
 * Thanks to Skinsmoke, below, for confirming in essence that the movant's slang terms are not only recently derived from popular music but are also limited geographically. There's a similar problem at Erection, with the sentence
 * "Erections during sleep or when waking up are known as nocturnal penile tumescence, informally called morning wood ".
 * This statement is referenced to http://h2g2.com/dna/h2g2/A12219374, which in fact discusses the Oasis slang term "morning glory" and not "morning wood". And, there's a vast difference between "informally called" as opposed to slang. (These are just two of a number of problems on that page, including a photograph of an engorged but not erect penis labeled as "flaccid". Flaccid properly refers to a penis that is not at all engorged: http://medical-dictionary.thefreedictionary.com/flaccid. Erection and apparently a few other pages could benefit from editing by a qualified urologist.) Milkunderwood (talk) 07:53, 16 February 2012 (UTC)


 * Oppose I can see no reason why the technical term should be changed to an American term that is practically unknown in other parts of the English speaking world.  Morning glory we may comprehend here in the United Kingdom (mainly thanks to the Oasis album), though it would need to be disambiguated as the normal use of the term would be the flowering plant.  Here, the "common" term for the condition is piss proud.  Skinsmoke (talk) 05:53, 16 February 2012 (UTC)

No Evidence of Beneficial Effects
As pointed out by User:MangoldOrganizer in the edit: https://en.wikipedia.org/w/index.php?title=Nocturnal_penile_tumescence&oldid=889919770

There is reasonable evidence that a full bladder can cause an erection and that an erection does inhibit urination, but there is no evidence that this is a reason why NPT may have evolved.

I have edited the page to make this clear and cited a reference but only as an example of the common belief, not evidence that the belief is common, so this citation may be un-necessary / poor. I have also added a citation giving some evidence to the point that an erection does inhibit urination, but a better reference would be good.

I suggest removing most of this paragraph as it is effectively 'original' (I added this some time ago) and In many years of occasionally looking for good evidence or references, have failed. Danmux (talk) 09:02, 29 March 2019 (UTC)


 * I have added a suggested edit in my sandbox User:Danmux/sandbox if there is no feedback I will make this edit soon. Danmux (talk) 09:28, 29 March 2019 (UTC)

Changes to introductory paragraph
I think it would be appropriate to change the sentence 'All men without physiological erectile dysfunction experience nocturnal penile tumescence, usually three to five times during the night, typically during rapid eye movement sleep.[1] Nocturnal penile tumescence is believed to contribute to penile health.[2]' as A. some men don't have penises and I don't think that is included in the phrase 'physiological erectile dysfunction' nor do I think they experience nocturnal penile tumescence (please correct me if I'm wrong) B. some people who identify as men have never had penises, and some people who have penises don't identify as men and C. sleep doesn't need to occur during the night time for nocturnal penile tumescence to occur. I think something like 'three to five times during a period of sleep' would be more accurate. — Preceding unsigned comment added by Charleshpeckhamv (talk • contribs)


 * Reverted the "genetically male" piece as not needed. I think it's clear we're talking about men with penises. And the Erection article is also about those men; it's not about clitoral erection.


 * On a side note: Per Talk page guidelines, newer sections go at the bottom. So I moved your post down. Also, you should sign your posts. See WP:Signature. I added a signature tag to your post. Flyer22 Reborn (talk) 22:56, 18 July 2019 (UTC)
