[[ADateWithRosiePalms Masturbation]] portrayed as being bad for you, possibly making you go blind[[note]]There is some slight truth to this, as both ocular humor and ejaculate contain zinc, thus chronic masturbation could, in extreme cases, lead to a zinc deficiency that could harm the eyes. Nobody's known to have actually gone blind from it, though.[[/note]], go deaf, or grow hair on your palms.

Another supposed result of masturbation was that it would make you go mad, though there was at least some reason for thinking this; asylum doctors would notice that many mentally disturbed people masturbated a lot, and reasonably ([[FalseCause though]] [[ScienceMarchesOn incorrectly]]), concluded that the madness was caused by masturbation.

Mostly a DiscreditedTrope we have [[OutgrownSuchSillySuperstitions outgrown]]. While certain Jewish and Christian groups still do frown on male masturbation because of the story of [[http://en.wikipedia.org/wiki/Onan Onan]] in the Old Testament, the idea that masturbation could cause actual, physical harm came from VictorianBritain and the Second Great Awakening in the US. These were the days of MoralGuardians like U.S. postmaster Anthony Comstock and Boy Scouts founder Lord Baden-Powell, who believed that children indulging in "Secret Practices" would waste away their youth and vigor, and scores of ministers whose most lasting innovations in hygiene turned out to be [[http://www.snopes.com/food/origins/grahamcrackers.asp Graham crackers]] and Kellogg's Corn Flakes.

The bitter irony? All those old wives' tales and warnings have been turned on their ear in recent years, particularly for male masturbation. Separate studies in 2003, 2004 and 2006 suggested that men who ejaculate regularly have a ''reduced'' risk of prostate cancer. The theory is that keeping the stores of seminal components from getting stale clears out carcinogenic impurities. It also probably helps preserve men's fertility (because if sperm are left in place to be reabsorbed, the body stops producing as much).

One of the reasons [[UsefulNotes/{{Pornography}} pornography]] has such a bad stigma connected to it is because it "[[OneThingLedToAnother incenses the mind to masturbate]]".

Not to be [[IThoughtItMeant confused with]] SelfHarm.

[[folder: Anime]]

* It may have been unintentional, but Nina Einstein's storyline from ''CodeGeass'' has echoes of this trope. Early in the first season, she's shown masturbating to a picture of [[spoiler: Princess Euphemia]] [[CargoShip using the edge of a table]]. Then [[spoiler: Euphemia dies]], starting Nina on a downward spiral in which she [[spoiler: threatens to blow up her school, pushes away her old friends, is manipulated into creating a FantasticNuke that kills 40 million people,]] and [[ArsonMurderAndJaywalking makes some truly grotesque facial expressions]]. While Nina's masturbation isn't stated to have caused her SanitySlippage, it helped characterize her as a PsychoLesbian, as well as one of CG's many [[TheScrappy Scrappies]].

[[folder: Film ]]

* In ''PoliceAcademy 2'', the disgruntled prankster recruit Mahoney swaps the overbearing [[DrillSergeantNasty man in charge of recruit training]]'s shampoo with fast-curing helmet repair epoxy. This has the desired effect of Supergluing the victim's hands to his head. When he finally manages to get his hands free, they are naturally covered with hair. When he asks a group of recruits if anyone can explain how this happened, Mahoney replies, "I can, sir. And if you don't stop, you'll go blind."
* ''{{Film/Avatar}}'' includes Dr. Augustine's blink-and-you'll-miss-it line as Jake is examining his new body's neural queue (in his hair, as a ponytail): "[[ParentalBonus Don't play with that, you'll go blind.]]"
* In ''PiratesOfTheCaribbean: Dead Man's Chest'', when the other crew members see the hairy black spot on Jack's hand (the mark of a curse), he's quick to say that his eyesight's as good as ever.
* In ''FullMetalJacket'', a story is told relating how one marine was going to be discharged on a Section 8 for his uncontrollable urge to masturbate, even in public. His nickname? [[ExactlyWhatItSaysOnTheTin Hand Job]].
* In ''SaintRalph'', the characters literally refer to it as "self abuse," a reflection of the 1950's Catholic school setting. However, since the title character is 14, the concept that it's bad for him does not stop him.
* Another Catholic school movie, ''HeavenHelpUs'', features a compulsive masturbator who's also pallid, twitchy and socially awkward.
* Referenced in ''[[AmericanPie American Wedding]]''.
-->'''Jim:''' Maybe Stifler can be nice, and nothing will go wrong.
-->'''Michelle:''' ...aw, sweetie. You've gotta stop masturbating. It's melting your brain.
* In TheLoveGuru, the protagonist is told by his severely crosseyed teacher that if he masturbates, it will make him crosseyed.
* Referenced in the titles of two R-rated sketch comedy films (basicaly ''LoveAmericanStyle'' with naked chicks): ''If You Don't Stop It You'll Go Blind'' and its sequel ''Can I Do It 'til I Need Glasses?''
** The latter is famous for [[OldShame being the much-regretted first movie]] of RobinWilliams.

[[folder: Jokes ]]
* There are plenty of jokes about how parents will lecture their children about masturbation and its negative consequences. One gem we heard a lot in school was about a dad who tells his son to stop masturbating or he will go blind... and his son then tells him that he is looking in the wrong direction and that he is standing over here.
* Variations on the theme of "Masturbating'll make you go blind, you know!" "Who said that?" and "Masturbation'll go make you go deaf!" "What? Speak up!" are always popular in junior high.
* Comedian Adam Ferarra claims to have renounced his Catholic faith at 14 years old for this reason.
-->(as priest) "Masturbation is a sin!"\\
([[BeatPanel beat]])\\
(as himself) "See ya!"\\
(as priest) "No, my child! You must repent!"\\
(as himself) "I'll apologize all you want, but... I'm doing it again!"\\
(as priest) "If you keep doing it you'll go blind!"\\
(as himself) "S'All right, I can still find it!"
* This point of view is hilariously mocked by Creator/MarkTwain in an 1879 speech he gave to a private club called [[http://www.textfiles.com/etext/AUTHORS/TWAIN/onanism.txt "On the Science of Onanism"]].
* BillCosby brilliantly lampooned the hypocrisy inherent in this trope in his "For Adults" album, with this exchange:
--> Father: Son, that'll cause blindness.
--> Son: Dad? <{{Beat}}> I'm over ''here''.
* Arnold Schwarzenegger stars in...''[[Film/TheTerminator The Masturbator]]''. Half man...half blind.

[[folder: Literature ]]
* Doctor Crombie, eponymous character in Graham Greene's short story, expounds that cancer is a result of masturbation... More accurately, he claims it is a cause of "playing with oneself", the euphemism giving rise to humour. The central theme of the story is to demonstrate the folly of conflating correlation and causation: "Almost one hundred per cent of those who died of cancer had practised sex".
* This is discussed in the memoirs of the real-life Casanova when he makes friends with a Turkish Muslim and they compare attitudes toward sex in their respective religions/cultures. Casanova subscribes to the view that too much masturbation will make you sickly and weak (of course, his solution is to deal with horniness by sleeping with everything that moves and relying on the sacrament of confession to keep you out of hell) while Yusuf says that obviously "too much" of anything is bad by definition, but there's nothing wrong with masturbation per se, and that anyway it's a completely unenforceable rule. They also talk about male vs. female masturbation, with Casanova saying that girls don't run the same risk as boys because they're not losing a bodily fluid every time they do it.
* Used sarcastically in ''Literature/AuntieMame'' when Patrick's roommate gets suspicious (what he's really doing at night is sneaking out to help Mame with a ZanyScheme she's suckered him into):
-->"...Say, what's the matter with you lately, anyways? You're always tired and I never see you at gym and you've got terrible circles under your eyes. You're not ''doing'' anything at night are you?"\\
I gulped. "Well, gosh, Junior..." Then I saw what he meant. "Yeah, sure I am, Junior. Six or seven times a night. It'll drive me crazy and no nice girl will marry me and all my kids will be idiots. Be sure to tell your old man that for me next time you write." I snatched up my towel and stalked off to the showers.
* Discussed in Creator/NealStephenson's ''Literature/{{Cryptonomicon}}''. Avi's of the opinion that masturbation takes the passion out of life.
* Unhappily married Samad in ''Literature/WhiteTeeth'' tries to cherry-pick the ambiguities in Islamic writings as to whether masturbation is okay or not- the imam tells him that he knows the answer- to 'stay away from his right hand!' That's fine with Samad: [[ExactWords his right hand is paralysed anyway]].

[[folder: Live Action TV ]]
* PlayedWith in an episode of ''Series/{{Supernatural}}''. Sam and Dean wind up in a town where all the old wives tales - like "your face will stick that way" - actually come true, and Dean realises it's affecting them when he ends up with hairy palms. Sam is not amused.
* ''Series/MysteryScienceTheater3000'', "Body Care and Grooming": "And remember, when you touch yourself, the saints cry. Good night."
* On ''MadMen'', a ten- or eleven-year-old Sally experimentally masturbates to ''TheManFromUNCLE'' while staying over at a friend's house. The friend's mother catches her, freaks out, takes her home, and tells her mother, who threatens to cut off her fingers if she ever does that again.
* In an episode of ''Series/TheGoodies'', Graeme is training rabbits in preparation of sending them into space.
-->'''Graeme:''' Now, I've left this one alone for six months to prepare him for the isolation. Let's see what he's--don't do that!
-->'''Tim:''' ''(laughing)'' He probably can't hear you.
-->'''Graeme:''' ...Pardon?
-->'''Tim:''' ...Oh, I'm so sorry.
* In ''StarTrekDeepSpaceNine,'' Ferengi ears are a source of FantasticArousal when touched (and thus, grabbing them when pissed is analagous to a GroinAttack.) There's a form of ear massage called "oomox." Naturally, there's a reference to an old wives tale giving yourself oomox too much making you go deaf.

* In England, a common rumor is that it causes deafness. In a Christmas episode of ''Radio/HelloCheeky'', it's mentioned that Denis King and his trio spend the winter hibernating under the couch with a copy of ''Playboy''. Thus:
-->'''Denis:''' What is it? I was--don't do that, Don, you'll go deaf!
-->'''John:''' He can't hear you, Denis.
-->'''Denis:''' ...What?
-->'''John:''' ...Right.

[[folder: Religion]]
* The Roman Catholic Church officially considers masturbation to be a grave sin. It's explicitly written in the Catechism (the big book of doctrine) that "deliberate stimulation of the genitals for sexual pleasure" is a grave matter that is capable of sending one directly to hell.
* However, the story as actually written in Literature/TheBible doesn't have a "masturbation is evil" moral: Onan (in Genesis 38) was told to - in accordance with the duty of a brother-in-law as per the rules of the time/place - have a child with Tamar, [[RomancingTheWidow the wife of his dead brother Er]]. He didn't want to give her a child that would not be considered truly his so (we'll ''try'' to make this as un-graphic as possible while preserving the meaning, which isn't easy) he had sex with her, pulled out, and 'spilled the seed' instead. God was displeased and struck Onan down. It seems pretty clear what God had a problem with - and Onan's intent was ''explicitly spelled out,'' even.
* Unlike Christianity, Islam is somewhat divided on masturbation. Some scholars consider it disliked by God but not considered a sin. If someone avoids a disliked action they would be rewarded by God. The more fundamentalist scholars see it as forbidden, full stop. There is a middle ground that states you can masturbate without porn to avoid immoral sexual desires and adultery. It's been shown that the Prophet's companions had masturbated while travelling, and during wars when their wives weren't present to give them much-needed gratification.

[[folder: Theatre]]
* In ''Theatre/TheBibleTheCompleteWordOfGodAbridged'', an Angel of the Lord is auctioning off God's favors to the greatest sufferer. The first bidder says, "I will suffer self-abuse and spill my seed on the ground." "Onan, that's not suffering," the angel tells him. "Well, it made me go blind," Onan says.
* Referenced by name in TheHistoryBoys:
-->'''Timms''': You've got crap handwriting, sir!
-->'''Irwin''': It's your eyesight that's bad, and we know what that's caused by.
-->'''Timms''': Sir! Is that a coded reference to the mythical dangers of self-abuse?

* ''LunarSilverStarStoryComplete'' for the PS1 had a part where the lights go out and leave the party blind. Kyle says "I can't see! I'm blind! But I thought that was only a myth!" to which Nall replies "What do you mean? The cave went dark!" Jessica says "Trust me, Nall, you DON'T want to know what he's talking about."

[[folder: Web Comics]]
* The "Mike's Left Hand" strips of ''Webcomic/SexyLosers'' are based on a RunningGag about a guy who's addicted to masturbation to the point of a {{Fetish}} -- he apparently can't get off any other way. He does it in all kinda of inappropriate situations and even passes up opportunities for actual sex in favour of it. A YetAnotherChristmasCarol parody strip has him warned that his death will be masturbation-related... somehow.
* In ''Webcomic/QuestionableContent'', Claire joked that her brother Clinton has a robotic hand because he masturbated his own off (according to Clinton, it got blown off in a fireworks accident).

* One episode of ''WesternAnimation/AmericanDad'' features Stan showing his son, Steve, an [[CrowningMomentOfFunny admittedly hilarious]] anti-masturbation propaganda film that ends with a boy screaming "[[BigNo NOOOOO!]]" as he's growing hair on his palms and his eyes melting out. The kid turns up (in a deleted scene) later in Stan's head and says something along the lines of "It was worth it."
