Who knows ? Maybe you could habituate one of these to shanghai your valentine — in fact , some of these could belike even be craft into ingenious pickup lines .
10. You can break a penis
There are no bones in the member , but it can , in fact , become “ broken . ” Doctors cite to the harm as a “ penile fracture,”and it ’s every moment as torturous as you ’d imagine.(All aright , so if you ’re going with the whole pickup arm wrinkle angle , you might not want to get going with this one . )

“ [ Penile faulting ] is a severe form of bending combat injury to the upright penis that takes place when a membrane called the tunica albuginea tears,”explains Hunter Wessells — chair of the urology section at the University of Washington School of Medicine . He remain :
The tunica albuginea surrounds the corpora cavernosa , specialized spongy tissue in the core of the member that fills up with blood during an erection . When the tunica albuginea snag , the blood that is normally throttle to this infinite leaks out into other tissues . You get wound and swelling .
So how does a penis really , you know , break ? fit in to Wessels , any form of vigorous intercourse when the penis is rammed into a hearty social organization … “ during sexual stunt flying , ” for instance .
“ We had this affected role who suffered penile cracking after run across the room and trying to dawn his wife with a flying leap , ” he says .
9. Ovulating strippers make more money (according to one poorly conceived study)
In 2007 , researchers at the University of New Mexicorecorded a surprising correlational statistics between strippers ’ ovulatory cycles and their hint profit . Strippers who were ovulating ( and thus most likely to conceive ) averaged $ 70 per time of day in hint . Those who were menstruating , and those who were neither flow nor ovulating , pulled in $ 35 and $ 50 , severally . One supposition for this unknown observation is that men are , subconsciously , more disposed to tip a woman who they believe they have a better fortune of bring forth a tyke with .
But take all of this with a grain of salinity . The investigation monitored a mere 18 professional dancer from one club for a amount of two cycles , throw it more than a little modified in scope and its sample size of it mete ridiculous . Needless to say , few were surprised when Geoffrey Miller , the researcher who channel this survey , was trounce by his university last yearfor lie about his inquiry in other arena .

8. Women can smell genetic incompatibility
The genes that comprise your major histocompatibility complex ( MHC ) play an important role in influence your physical structure ’s immune response — most notably in determining compatibility of donors for organ transplant . Some data have shown that the more different a man and cleaning woman ’s MHC are , the more likely they are to bestow a child to term — but even more interesting is that women are think to be capable of in reality smelling this genetic difference .
In a study top by Claus Wedekind at the University of Bern in Switzerland , women were ask to smell deoxythymidine monophosphate - shirts that had been worn by anon. men for two nights and choose ones which appeal to them . According to the researchers , the women systematically preferred the smell of shirts worn by men with different MHCs .
How the whole smelling thing works remains very much a mystery . Research has shown that mice find compatibility gene by smell , as do some species of Pisces the Fishes . Butin an interview withThe Guardian , researcher Daniel M. Davis , author ofThe Compatibility Gene , hold that , at least for human , “ how [ MHC signal detection ] wreak on the olfactive level is basically not understood at all . ”
7. Birth control could mess with a woman’s ability to assess a mate
In the subject area conducted by Wedekind and his co-worker , the womens ’ preference for men of dissimilar MHCs was actually change by reversal when the women fink the odors were taking oral contraceptives .
6. Fat men last longer in bed
The family relationship between obesity and intimate health is sort of a mixed bag . On one hand , obesity is associated with erectile dysfunction ; on the other , study like this one — bring out in 2010 in the International Journal of Impotence Research : The Journal of Sexual Medicine — suggest that the fatter a man is , the less potential he is to suffer from untimely interjection . In fact , men with a higher soundbox mass index ( BMI ) , were able-bodied to make love for an norm of 7.3 minute , while slimmer test issue averaged 1.8 minutes .
So what ’s the secret behind those supererogatory five and a half minutes ? man with supererogatory fat also pack higher degree of the distaff sex hormone estradiol . One hypothesis is that this means interferes with the the dead body ’s power to accomplish orgasm … at least for a few minutes .
5. The seven year itch may not be a myth
in the beginning made famous inthe 1955 film by the same name , the phrase “ seven - twelvemonth - itch ” is used to key the tendency for someone to become restless with their better half or marriage ceremony after a menses of seven yr , at which point they may find an urge to move on .
If you ’re measure by means of divorcement , the myth of the seven year urge may not be a myth after all ; according to the 2009 U.S. Census Bureau , the medial duration of first marriages that end in divorcement is 7.9 years .
4. We will actively avoid temptation
Even if the seven year itching is real , evidence also suggests thatmen and womanhood will actually avert their attention from tempt alternatives to their partners — even if this aversion is subconscious .
In a study published in 2008 , psychologist Jon K. Maner showed virile and female test subjects moving-picture show of faces on a computer screen for half a secondment , followed immediately by a roach or straight on some other part of the computer blind , which they were asked to identify by pressing a comparable keyboard key as quickly and accurately as potential .
The results show that the gazes of individual , heterosexual men and women were liable to lollygag on photographs of attractive members of the paired sex , in what the researchers refer to as a gamey level of “ attentional adhesion . ” But the trial run depicted object who were already in relationship reacted otherwise , and in reality looked away from attractive expression more quickly ; in fact , some trial participants in relationship turned their attention forth from “ attractive ” members of the opposite sex more speedily than they did from “ average ” looking faces .
3. Masturbation starts in utero
Those of you flying solo on Valentines solar day should know that onanism is nothing to be ashamed of — in fact , there ’s a chance you ’ve been commit it since you were in the womb . What you see here is a sonographic image from a newspaper title “ Sonographic observance of in utero foetal ‘ onanism . ’ ” In the image on the left , the baby ’s hand can be seen hovering above the penis . In the image on the right , the yellow arrow demonstrate the hand engaged in what research worker Israel Meizner describes as “ the hand grasping the penis in a mode resembling onanism drift . ”
“ Bear in mind , ” excuse Mary Roach — writer of Bonk : The Curious Coupling of Science and Sex — ather TED talk on things you did n’t acknowledge about orgasms , “ this was an sonography , so [ Meizner would have observed ] move images . ”
Then again , who knows ? perhaps there ’s nothing sexual about this image at all , and it ’s actuallyan example of the palmar grasp reflexin the womb . [ soma by Meizner et al . viaTED ]

We covered the enigmatic clitoris in slap-up detailherebut the effect is that prior to the late XC , researcher had never studied the internal structure of an excited clitoris . In fact , it was n’t until 2009 that scientists produce the first 3D ultrasound of a stimulated clit . The intimate organ is portray here in its excited state in an exemplification by the Museum of Sex Blog ’s Ms. M , which she drew forthis fascinating post on the internal button .

But there is hope for sufferer of POIS . According to two discipline published by research at Utrecht university , men with the syndrome may just be allergic to their own cum , a determination that could open doorway to helpful therapeutic options .
In the first study , 88 percent of men diagnose with POIS were subject to a skin - prick test ( using a dilute form of their own semen ) and had a positivist skin response indicatory of an allergic reaction . In the second field of study , men name with poi were regale with hyposensitization therapy ( which is commonly used to treat allergic reaction ) , which involved exposing the patients to skin injection curb increase amount of their own semen . The subject expose that over the course of three years , the gentleman showed a significant drop in their POIS symptom .
