new research finds the size and shape of your balls may explain more about you than you think.

新研究發現，你的睪丸大小和形狀可能比你想像的更能解釋你。

So today we are going to explain the shocking science behind human testes.

所以今天我們要來解釋人類睪丸背後的驚人科學。

Unlike an elephant, where the testicles are deep within the body cavity, us primates have ours hanging outside of us in a sack.

和象類不同，牠們的睪丸深藏在體腔內，而我們靈長類則是將牠們掛在體外的一個囊袋裡。

And compared to dolphins, whose testicles are huge and make up around 4% of their body weight, the equivalent of human testicles weighing roughly 9.9 pounds or 3 kilograms, you might think in general, ours are small.

相較於海豚，牠們的睪丸巨大，佔體重的 4% 左右，相當於人類睪丸重約 9.9 磅或 3 公斤，你可能會覺得，總的來說，我們的睪丸很小。

But to understand more about our human testicle size and how your junk stacks up, we shouldn't be looking at other species like dolphins, but

但要更瞭解我們人類睪丸的大小，以及你的陽具如何，我們不應該看海豚這類其他物種，而是

Relative to body weight, the human testicle is triple the size of a gorilla, but

相對於體重，人類睪丸的大小是銀背大猩猩的三倍，但

The variation in testicle size amongst primates has to do with two scientific pre mating and postmating sexual selection.

靈長類之間睪丸大小的差異，與兩種科學的婚前性選擇和婚後性選擇有關。

Pre mating sexual selection in primates involves badges of status.

靈長類的婚前性選擇涉及地位標誌。

These are physical traits that signal social dominance and the potential for mal reproductive success.

這些是能顯示社會支配地位和男性生殖成功潛力的外觀特徵。

Essentially, badges of status are physical appearances that help male primates get laid.

基本上，地位標誌就是能幫助雄性靈長類成功交配的外觀特徵。

Examples include the larger noses of the proboscis monkeys.

The larger the nose, the more likely to get laid.

Other examples include the redder the patch of the galates or the larger the cheek flanges of orangutans.

其他例子包括狐猴較紅的斑塊，或是紅毛猩猩較大的臉頰瓣。

Some studies indicate that the thickness of beards in Homo sapiens could be a pre mating badge of status.

有些研究指出，人類的鬍鬚厚度可能是婚前地位標誌。

Since my badge of status, y', all, is it working?

因為我的地位標誌，你們，它有效嗎？

Post mating sexual selection has to do with the sexual selection that happens after the primates have gotten laid.

婚後性選擇，就是指靈長類交配後發生的性選擇。

For example, the quality and amount of sperm production happening within the testicles themselves.

舉例來說，就是睪丸本身製造的精子品質和數量。

Male success relies on a combo of pre mating success and post mating success.

男性的成功，是靠婚前成功和婚後成功的組合。

What is fascinating is that research has found the showier the badge of status, the smaller the testicles.

有趣的是，研究發現地位標誌越華麗，睪丸就越小。

AKA large flange, Small balls, large nose, small balls, redder the patch, smaller the testes.

也就是說，臉頰瓣越大，睪丸越小；鼻子越大，睪丸越小；斑塊越紅，睪丸越小。

This led researchers to do more studies, including one on howler monkeys.

這讓研究人員做了更多研究，包括對吼猴的研究。

And again it was found howler monkeys with the most developed thyroid and larynx, AKA the ones who could broadcast the loudest low formant frequency vocalizations used to attract mates had the smallest balls.

結果又發現，甲狀腺和喉部最發達的吼猴，也就是那些能發出最響亮、吸引配偶的低頻聲音的吼猴，牠們的睪丸是最小的。

And even study on human male testicles found correlations to voice pitch.

甚至對人類男性睪丸的研究，也發現了與聲音音調的關聯。

Men with lower more attractive sounding voices tended to have lower sperm counts.

聲音較低沉、聽起來較有魅力的男性，其精子數量往往較少。

It's most likely due to the evolutionary trade offs between pre mating and post mating sexual selection, AKA the energy needed to maintain these physical badges of status versus the energy needed to maintain testes mass.

這很可能是因為演化上的權衡取捨，也就是婚前性選擇與婚後性選擇之間的取捨，也就是維持這些地位標誌所需的能量，與維持睪丸大小所需的能量之間的取捨。

It's been found that the larger the testicles, the more sperm produced, and

研究發現，睪丸越大，產生的精子越多，

this has been well established in human males too.

這在人類男性身上也得到了充分證實。

Men with larger testicles generally produce more sperm, and

睪丸較大的男性通常會產生較多的精子，

that's likely due to the simple fact that larger testicles contain more seminiferous tubules, which is the sperm producing tissue in the animal kingdom.

這很可能是因為較大的睪丸含有較多的生精小管，而生精小管是動物界中產生精子的組織。

The males that invest increased energy into badges of status have more access to females, therefore decreasing their need to invest in testicular size.

投入更多能量於地位標誌的雄性，能有更多機會與雌性交配，是以降低了牠們在睪丸大小上投入的必要性。

Because there's less sperm competition between males, the big nose gets them laid, so they don't need bigger balls to produce more sperm.

因為雄性之間的精子競爭減少了，大鼻子讓牠們能順利交配，所以牠們不需要更大的睪丸來產生更多精子。

So increased investment by males into badges of status decreases sperm competition, which then relaxes the selection pressure of sperm production, ultimately decreasing ball size.

是以，雄性對地位標誌投入的增加，減少了精子競爭，進而減緩了對精子生產的選擇壓力，最終導致睪丸大小縮小。

Extrapolating to humans here, maybe men who can grow the thicker beards do have the smaller crown jewels.

套用到人類身上，也許鬍子比較濃密的男性，他們的「寶貝」反而比較小。

There is no adequate studies on this, but

這方面的研究還不夠充分，但是

one survey and study found men with larger testes spent less time doing childcare, less time changing diapers and less time looking after their family compared to men with smaller balls.

有一項調查研究發現，睪丸較大的男性，陪伴孩子的時間較少，換尿布的時間較少，照顧家人的時間也比睪丸較小的男性少。

This does kind of link to other studies on primates.

這似乎也跟其他關於靈長類的研究有關聯。

These fine gorillas and kolobos monkeys have smaller balls because they are more likely to mate exclusively, whereas apes who have sex with lots of partners, like macaques, have larger balls due to sperm competition.

像這些漂亮的紅毛猩猩和長鼻猴，牠們的睪丸比較小，因為牠們比較可能進行單配偶制；而像獼猴這類與許多伴侶交配的猿類，則因為精子競爭而擁有較大的睪丸。

Maybe the men with big balls are bad dads because they're less likely to want to be monogamous and are therefore less caring towards their families.

也許睪丸大的男性是壞爸爸，因為他們比較不可能想要單配偶制，是以對家人比較不關心。

Tis an extrapolation, but maybe if you are looking for a committed partner.

這是一種推論，但或許如果你正在尋找一個忠誠的伴侶。

但他有又大又鬆弛、垂下來的睪丸。

There are no valid studies on that, but what about the droop?

沒有關於那方面的有效研究，但那下垂呢？

如果一個比另一個垂得更低呢？

Human scrotal descent is likely linked to the fact that sperm production and storage is maxim at cooler temperatures.

人類陰囊下降很可能與精子產生和儲存的最佳溫度較低有關。

It's why the skin on our scrotal sac is so thin and why the arteries that supply blood to the scrotum are right beside the veins.

這就是為什麼我們的陰囊皮膚這麼薄，以及供應陰囊血液的動脈為何緊鄰靜脈。

Another cooling and heating exchange mechanism to keep the balls cooler.

另一種冷卻和加熱交換機制，用來讓睪丸保持涼爽。

In general, scrotal temperature is 2.5 to 3 degrees Celsius lower than body temperature, which is most efficient for the creation of sperm.

一般來說，陰囊溫度比體溫低攝氏 2.5 到 3 度，這對精子製造最有效率。

It's also why when it's cold outside, the scrotum shrinks and pulls closer to the body to use its warmth and keep the testicles at the correct temperature.

這也是為什麼外面冷的時候，陰囊會收縮並靠近身體，利用體溫來保持睪丸在正確的溫度。

There are muscles called cramiscaric muscles which serve to retract when it's cold and relax when it's warm to regulate that temperature.

有一種叫做提睪肌的肌肉，在天冷時會收縮，天熱時會放鬆，來調節溫度。

The interesting thing is that each testicle moves in its own orbit as a way of maximizing the available scrotal surface for cooling.

有趣的是，每個睪丸都會在自己的軌道上移動，以最大化陰囊表面積來散熱。

So for this reason, there's a lot of lopsidedness in the balls as the testicles try to cool themselves independently.

所以因為這個原因，睪丸在試圖獨立冷卻時，會有很大的傾斜。

Also, the sac will tighten and the balls will move closer to the body upon arousal, likely to help the sperm warm up and prepare for ejaculation into the warm vagina.

另外，在興奮時，陰囊會收緊，睪丸會靠近身體，這可能是為了幫助精子預熱，並準備射入溫暖的陰道。

But it also has another added evolutionary advantage, keeping the sac and the balls closer to the body during the vigorous thrusting of sex as to not damage or hurt them.

但這還有另一個額外的演化優勢，就是在性行為劇烈抽插時，將陰囊和睪丸靠近身體，以免損傷或傷害到它們。

And as for the droopiness of the ball sack, this will vary from one man to another.

至於陰囊的下垂程度，這會因人而異。

Just like some people have different sized hands, some people have different sized spermatic cords, or a scrotum with more surface area and looser volume.

就像有些人手的大小不同，有些人精索的大小不同，或陰囊的表面積較大且體積較鬆。

Okay, this can sometimes lead to a droopier default position.

好的，這有時會導致預設位置比較下垂。

I don't know what else to tell you, except that one thing is for certain.

我不知道還能說什麼，但有一件事是確定的。

Everyone will age and the skin will lose elasticity and collagen throughout your body.

每個人都會老化，全身的皮膚都會失去彈性和膠原蛋白。

So, yes, as you age, your balls will become droopier.

所以，是的，隨著年齡增長，你的睪丸會變得更下垂。

That's an exciting thing to look forward to.

And if you've ever noticed that one ball is larger than the other, that's completely normal, too.

如果你曾注意到一顆睪丸比另一顆大，這也很正常。

In fact, for most men, the right testicle is slightly larger than the left, whereas the left testicle is more likely to hang lower.

事實上，對大多數男性來說，右邊的睪丸會比左邊稍微大一點，而左邊的睪丸則比較容易下垂。

Again, this all links back to your personal anatomy.

這一切都跟你的個人生理結構有關。

At the end of the day, if your balls hang low, if they wobble to and throw, if you can tie them in a knot, if you can tie them in a bow, if you can throw them over your shoulder, you likely have a goodness world record and should probably contact someone.

說到底，如果你的睪丸下垂，左右搖擺，你可以把它們打結，綁成蝴蝶結，甚至甩到肩膀上，那你很可能創下了世界紀錄，應該聯絡一下相關人士。

But truly, as primates, our testicles, shape and size and droopiness are a fascinating part of our evolutionary history.

但說真的，身為靈長類，我們的睪丸、形狀、大小和下垂度，是我們演化史上一個引人入勝的部分。

There's even some recent research on sexual selection proving that our ball size, compared to other parts of our body, is likely to change more due to evolutionary pressures.

甚至有近期的性選擇研究證明，相較於我們身體的其他部位，我們的睪丸大小很可能會因為演化壓力而有更多變化。

Therefore, in the future, our balls might shrink or grow.

是以，未來我們的睪丸可能會變小或變大。

And looking into the past, they've had many different sizes and shapes leading up to our pre ancestors.

回顧過去，在我們祖先出現之前，牠們已有過許多不同的尺寸和形狀。

Thank you so much for watching this video.

Honestly, we found this information fascinating.

說真的，我們覺得這些資訊非常引人入勝。

Your balls are very intricately linked to evolutionary history in primates, which you are.

你的睪丸跟身為靈長類的我們，演化史有著非常緊密的連結。

Thank you so much for watching and we will see you soon for a new science video.

非常感謝收看，我們很快就會在新的科學影片再見囉。
