  • Maybe it was love at first sight, or perhaps it's finally wedding bells for the happy couple.

  • Either way, today is ending only in one way, with sweet marital bliss in the bedroom.

  • That's right, it's time for a bit of how's your father, as our British cousins would

  • say, or to lay one down for Ol' Glory for our American viewers.

  • But what's all the fireworks business about- what exactly is an orgasm, why do we do it,

  • and why does it feel so good?

  • It's time to quit the laughing and snickering in the back row, because Infographics is putting

  • on a sex ed class.

  • Hey, it could be worse, it could be your parents teaching you this stuff.

  • The word orgasm comes from the greek word 'orgasmos', meaning excitement or swelling,

  • and is typically the culmination of sexual intercourse- though not always.

  • For men an orgasm is the grand crashing cymbal, and the older you get the more likely that

  • it will be a one-shot performance for the evening.

  • In males, orgasms come in two stages, the emission of semen and then a refractory period,

  • during which the male must recover before another orgasm is possible.

  • Unlike women, men are physiologically incapable of having a second orgasm until their recovery

  • period is up, as their bodies need time to recover from the physical exertion of the

  • emission of semen.

  • And the male body does indeed come under incredible exertion when it ejaculates, shooting semen

  • at a whopping ten miles an hour- fast enough to get you a speeding ticket in most hospital

  • emergency room zones.

  • That speed, and the orgasm that builds the body up to generating it, are crucial though

  • for the ultimate purpose of making the beast with two backs- pregnancy.

  • Sperm have a long, twisting road ahead of them if they want to fulfill their life's

  • goal of fertilizing an egg, and the extra speed helps propel them along, a goodbye gift

  • from their donor, you.

  • Unlike many women, men are completely unable to halt their orgasm once they begin the process.

  • Once you pull that rip cord, there's no getting back in the plane guys, so you better be sure

  • you've been cleared for a landing.

  • The male orgasm begins seconds before ejaculation, with the testicles and penis contracting powerfully,

  • as the semen races from storage to blast off, and about three seconds later, the inevitable

  • happens.

  • The greater pleasure a man feels during an orgasm, the greater the volume of ejaculate,

  • helping ensure pregnancy by delivering more egg-fertilizing semen to the woman.

  • Female orgasms are both similar, and different from male orgasms.

  • For starters, they're far more complicated affairs, and require a greater amount of stimulation

  • or concentration to achieve.

  • Men might be the wild shooting pistoleros of the wild west, firing off every which way,

  • but women require greater focus and effort to achieve their own orgasm.

  • To even the score though, women are capable of repeated orgasms with no interruption in

  • between, unlike their male counterpart which needs longer and longer periods of rest in

  • between an orgasm the older they get.

  • As long as a woman's stimulation doesn't dip below plateau levels, she can orgasm very

  • quickly after the first, while her male partner may need a long breather.

  • Women may be capable of more frequent orgasms, but achieving an orgasm is typically much

  • harder for a woman than a man.

  • While a man's nerve endings run along the head and shaft of the penis, a woman's vagina

  • has far fewer nerve endings overall, and thus regular penetration may not be sufficient

  • for an orgasm.

  • The most common way for a woman to orgasm instead is through stimulation of the clitoris,

  • which is packed with nerve endings and is very sensitive.

  • Sometimes the clitoris can be stimulated through regular vaginal penetration, but most of the

  • time it must be specifically stimulated.

  • Because it is homologous to the penis, the clitoris is packed with over 8,000 nerve endings,

  • giving it as great sensitivity- or possibly greater- as the male penis.

  • Overall, the interior of the vagina has less nerve endings than the male penis, which makes

  • it difficult for women to orgasm during normal penetrative sex.

  • Some biologists believe that the difficulty in achieving a female orgasm may be due to

  • the fact that it serves a far lesser role in reproduction than the male orgasm.

  • Men, which carry the sperm needed to fertilize an egg, need a physiological process by which

  • to release that sperm only at the proper time.

  • If the process of having an orgasm was easier, i.e. if a man could have an orgasm with far

  • less stimulation, it might lead to orgasms in situations that serve no reproductive purpose,

  • wasting precious sperm and the energy required to produce it.

  • By requiring protracted and pleasurable stimulation of the penis, the body ensures that precious

  • sperm is delivered only under the very specific circumstances of reproduction.

  • In essence, the orgasm is like the safety on a gun, preventing it from going off except

  • for under very specific circumstances.

  • While conserving sperm may not seem like a big deal, producing it is in fact a costly

  • endeavor in terms of precious energy, and evolution always plays things conservatively.

  • When our ancestors were running around the African savannahs and hunting for their next

  • meal, every ounce of energy that could be conserved helped ensure our continued survival.

  • It's exactly because of the nature of the male orgasm though that leads some biologists

  • to posit that the female orgasm is purely vestigal, a leftover trait from when we were

  • a far more primitive lifeform.

  • After all, for the process of reproduction, the female orgasm doesn't seem to have any

  • obvious use, and data on it is both rare and inconclusive- though three theories exist

  • as to the presence of the female orgasm.

  • The first is known as the 'poleaxe' theory, and it states that female orgasms help the

  • woman to relax which in turn encourages her to lie down.

  • Lying down is believed to help semen travel to its destination with greater ease, but

  • the data on this is very inconclusive.

  • The second theory is the 'upsuck' theory, which posits that the contractions involved

  • in the female orgasm helps to hoover up male sperm.

  • In some studies conducted, the amount of male sperm that leaked out of the vagina shortly

  • after sex was less in women who had experienced an orgasm shortly before male ejaculation.

  • This might also help to move sperm deeper into the woman's reproductive system and ensure

  • fertility.

  • The third theory is that the orgasm once served an evolutionary purpose, but does not do so

  • any longer.

  • It is thought that for a woman, an orgasm once kicked open the doors to ovulation, making

  • them prime for reproduction.

  • This after all is true about cats today, as the female will not ovulate if she hasn't

  • copulated yet.

  • Evolutionarily speaking, this would be a major advantage to our ancient ancestors, as it

  • would ensure that fertilization and the ensuring pregnancy would come at a desired time, with

  • a desired partner.

  • As a form of birth control, the orgasm would have ensured that a woman was truly ready

  • to have a child, as it would have required multiple sessions of intercourse to begin

  • the process of ovulation.

  • This would prevent unwanted pregnancies from rape or unsuitable partners, and the female

  • could hold off until situations were optimal for the inevitable pregnancy to follow.

  • With one of the world's longest lasting pregnancies, having a child was an incredible investment

  • of time and energy, and our ancient ancestors may have needed the orgasm to help them control

  • reproduction until the environment and the social situation was suitable for childbirth.

  • This remains only a theory however, as it's unlikely that men, who experience a very powerful

  • evolutionary urge to procreate, would have willingly submitted themselves to extremely

  • long periods of chastity.

  • Another theory is that the female orgasm serves to emotionally bond a woman to her lover,

  • and indeed during both the male and female orgasm the brain releases bonding chemicals

  • that work to make us feel closer to our sexual partner.

  • As a strong family unit was critical for child rearing during our ancient past, this would

  • have been a great boost to ensuring that a male remained with his pregnant partner, and

  • helped provide for her and the child.

  • Likewise, the bonding chemicals released by the female orgasm would make a woman more

  • likely to stick with her partner and increase the odds of his own successful fertilization.

  • In a way, the female orgasm may have been an evolutionary trick to help men by making

  • women more likely to stay with their partner long enough to get pregnant by him.

  • The vagina and penis however aren't the only way to orgasm, and both men and women- though

  • men much more frequently- can orgasm from anal stimulation.

  • For both sexes, nerve endings can be found in great quantities around and just inside

  • the anus, and stimulation of these can lead to orgasm.

  • A male orgasm resulting from anal stimulation is typically longer, more pleasurable, and

  • more widespread than a traditional orgasm.

  • The same can be true for women, though the proximity of the pudendal nerve, which runs

  • via offshoots to the clitoris, can lead to much easier orgasms for women than men.

  • Recently though, doctors confirmed a long-standing rumor that women could achieve orgasms via

  • stimulation of their nipples alone.

  • A study in 2011 using an MRI machine discovered that during stimulation of the nipples, some

  • women were able to achieve an orgasm.

  • The doctors discovered that the pleasurable sensations from nipple stimulation traveled

  • to the same area of the brain that receive sensations from the vagina, clitoris, and

  • cervix, and could thus create orgasms in a small amount of the female population.

  • Evolution is all about one thing and one thing only: creating the next generation and successfully

  • passing one's genes down.

  • For this purpose, the orgasm is both a compelling tool for procreation, and a physiological

  • process to ensure successful fertilization.

  • While most monkeys and apes are believed to orgasm, it's not known if other animals do,

  • and it may be only us and our nearest ancestors that get to experience these happy little

  • endings.
