Erectile dysfunction rates have increased from 5% in 1999 to 34% in 2018.

勃起功能障礙率從 1999 年的 5%上升到 2018 年的 34%。

The most intense part of this data is this is all for men under 40.

最重要的是，這些數據都是 40 歲以下男性的數據。

I repeat, men under 40 are suffering from increased erectile dysfunction at rates we have never seen before.

我再說一遍，40 歲以下男性勃起功能障礙的發病率正以前所未有的速度上升。

A recent study found that by 2025, this year, 322 million men are expected to have erectile dysfunction, up from 152 million men in 1995.

最近的一項研究發現，到 2025 年，也就是今年，預計將有 3.22 億男性患有勃起功能障礙，而 1995 年的患者人數為 1.52 億。

Another study found young men are buying boner medication like Cialis and Viagra at the highest rates we've ever seen.

另一項研究發現，年輕男性購買西力士和萬艾可等壯陽藥的比例達到了我們所見過的最高水準。

So what is the reason that, in general, penises are softening?

那麼，一般來說，陰莖變軟的原因是什麼呢？

It's hard to wrap your head around, or should I say soft to wrap your head around?

你很難理解，或者我應該說你很難理解？

好了，讓我們來了解一下科學的原因。

Erectile dysfunction is defined as the inability to achieve or maintain a sufficient erection to engage in sexual intercourse.

勃起功能障礙是指無法達到或維持足夠的勃起以進行性交。

To be honest, getting an erection is hard.

我不會再開任何難聽的玩笑了。

It requires complex coordination between your endocrine system, your nervous system, the vasculature of your body, and your penis.

這需要內分泌系統、神經系統、身體血管和陰莖之間的複雜協調。

Therefore, many things can go wrong along the way.

是以，一路上可能會出現很多問題。

In general, there are two specific types of erectile dysfunction.

一般來說，勃起功能障礙有兩種具體類型。

Physiological ED, this can be due to damaged or aged vasculature in the penis, hormonal issues, drug-induced, et cetera, or you can have psychological ED.

生理性 ED，這可能是由於陰莖血管受損或老化、荷爾蒙問題、藥物誘發等，也可能是心理性 ED。

This is the most common type for young people right now.

這是目前年輕人最常見的類型。

Let's start with some fascinating reasons for physiological ED.

讓我們先來看看生理性 ED 的一些迷人原因。

One shocking reason is due to decreased smooth muscle growth and arterial insufficiency in the penis and gooch due to biking.

其中一個令人震驚的原因是騎自行車導致陰莖和陰囊平滑肌生長減少和動脈供血不足。

A survey of 160 cyclists on a Norwegian bicycle tour found 21% had penile numbness with 13% experiencing temporary impotence.

一項針對 160 名挪威自行車旅行者的調查發現，21% 的人陰莖麻木，13% 的人出現暫時性陽痿。

A more recent cross-sectional study found that men who ride bikes more than three hours per week have an increased risk of developing physiological erectile dysfunction.

最近的一項橫斷面研究發現，每週騎自行車超過三小時的男性患生理性勃起功能障礙的風險會增加。

As someone who bikes about an hour a day, that's seven hours a week, that's more than three hours a week, I'm a little bit worried about this information.

作為一個每天騎一個小時自行車的人，一週騎七個小時，也就是每週騎三個多小時，我對這些資訊有點擔心。

I'm gonna choose to live in ignorance, continue to pedal, and slam my gooch against that bike seat.

我要選擇活在無知中，繼續蹬車，用我的 "小弟弟 "撞擊自行車座。

Physiological ED can also be caused by smoking or vaping.

吸菸或吸食毒品也可能導致生理性 ED。

I found five large studies on how smoking is a risk factor for developing physiological ED.

我發現有五項大型研究表明，吸菸是導致生理性 ED 的危險因素。

And when it comes to vaping, one reason why young men are having more erectile dysfunction, some scientists think, is due to the trend in young men vaping.

說到吸菸，一些科學家認為，年輕男性勃起功能障礙增多的原因之一就是年輕男性吸菸的趨勢。

This is because vaping can mess up the vasculature of your dick.

這是因為吸菸會擾亂雞巴的血管。

尼古丁是一種強烈的血管收縮劑。

Therefore, it can significantly reduce blood flow to the male and female genitals during sexual activity.

是以，它能大大減少性活動時男性和女性生殖器的血流量。

This may also be why young women are suffering from lower libido rates as well.

這可能也是年輕女性性慾低下的原因。

For example, a survey found 32% of women aged 18 to 29 had a lack of sexual desire, 26% were unable to achieve orgasm, and 19% had trouble lubricating.

例如，一項調查發現，在 18 至 29 歲的女性中，32% 的人缺乏性慾望，26% 的人無法達到性高潮，19% 的人潤滑困難。

Some scientists think this could be linked to the increased consumption of nicotine in younger people.

一些科學家認為，這可能與年輕人尼古丁攝入量增加有關。

And then there's the weed smoking, scared.

One study found a 70% prevalence of ED in those using cannabis.

一項研究發現，在吸食大麻的人群中，ED 的發病率高達 70%。

That's an extremely high number, also a very small study, gonna choose to live in ignorance again.

這是一個非常高的數字，也是一個非常小的研究，要選擇再次生活在無知中。

I'm not gonna live in ignorance, this is serious information.

我不會生活在無知中，這是嚴肅的資訊。

It does show that high doses of cannabis can cause vascular erectile dysfunction because there are cannabinoid receptors in the hypothalamus of your brain, which THC binds to.

研究確實表明，大劑量大麻會導致血管勃起功能障礙，因為大腦下丘腦中存在大麻素受體，四氫大麻酚與之結合。

But this is also a part of the brain involved in regulating erectile dysfunction.

但這也是大腦參與調節勃起功能障礙的一部分。

These receptors being affected during the consumption of weed may lead to a change in regulation of erections.

這些受體在吸食大麻時受到影響，可能會導致勃起調節發生變化。

There is a lot of research happening into cannabis and erectile dysfunction right now because again, we see young men are having ED and young men are also consuming more cannabis than ever before.

現在有很多關於大麻和勃起功能障礙的研究正在進行，因為我們再次看到年輕男性患有 ED，而年輕男性的大麻消費量也比以往任何時候都多。

One study found that lower consumption of fruits and vegetables increased the risk of ED.

一項研究發現，水果和蔬菜攝入量較低會增加罹患 ED 的風險。

With some studies showing the rise in young men partaking in keto or all meat diets causing increased erectile dysfunction.

一些研究表明，參與酮類或全肉飲食的年輕男性增加，導致勃起功能障礙增加。

In order to lower your risk of ED, one study found that consuming at least 150 grams of vegetables, 300 grams of fruits and 30 grams of nuts per day can lead to a decrease in erectile dysfunction.

為了降低勃起功能障礙的風險，一項研究發現，每天至少攝入 150 克蔬菜、300 克水果和 30 克堅果可以減少勃起功能障礙。

The reason for this is that these foods are more likely to contain nutrients that reduce endothelial dysfunction and inflammation.

原因是這些食物更有可能含有減少內皮功能障礙和發炎的營養素。

Another study found that men who partake in the Mediterranean diet are more sexually active.

另一項研究發現，參與地中海飲食的男性性生活更活躍。

Although there aren't really any ways to understand if this diet is exactly the reason for the sexual activity, there's a lot of other variables involved.

雖然還沒有辦法確切瞭解這種飲食是否是導致性活動的原因，但這其中還存在很多其他變數。

Drugs such as ecstasy and ketamine can lead to physiological ED as well.

搖頭丸和氯胺酮等藥物也會導致生理性 ED。

And opioid users are eight times more likely to get erectile dysfunction compared to non-users.

而阿片類藥物使用者患勃起功能障礙的機率是非使用者的八倍。

This is because opioids can block gonadotropin releasing hormone, decreasing testosterone in men.

這是因為阿片類藥物會阻斷促性腺激素釋放激素，從而降低男性的睪丸激素。

In general, lower testosterone levels can be linked to erectile dysfunction.

一般來說，睪酮水準降低可能與勃起功能障礙有關。

And this could be part of the reason why as you age, you're more likely to get ED.

這可能是隨著年齡增長，更容易患上 ED 的部分原因。

One study found there was a four-fold increase in ED in men in their 70s compared to their 20s with 52% of men between the ages of 40 to 70 having erectile dysfunction.

一項研究發現，與 20 多歲的男性相比，70 多歲的男性勃起功能障礙患者增加了四倍，40 至 70 歲的男性中有 52% 出現勃起功能障礙。

As you age, testosterone levels can decrease, sometimes to the point that you need androgen replacement therapy.

隨著年齡的增長，睪酮水準會下降，有時甚至需要進行雄激素替代治療。

It's important as you age to get your hormone levels checked, especially if you're feeling lethargic, depressed, you have low libido.

隨著年齡的增長，檢查荷爾蒙水準是很重要的，尤其是當你感到嗜睡、抑鬱、性慾低下時。

These are reasons you could talk to your doctor and get your hormone levels tested.

是以，您可以諮詢醫生並檢測自己的激素水平。

To deal with erectile dysfunction as you age, androgen therapy and Cialis and Viagra, erectile dysfunction meds like that can work together to get your boner back.

為了解決隨著年齡增長而出現的勃起功能障礙，雄性激素療法和西力士、萬艾可等勃起功能障礙藥物可以一起發揮作用，讓你重新勃起。

Alcohol is also a significant contributor to ED, but there's a curvilinear effect to moderate drinking.

酒精也是導致 ED 的一個重要因素，但適度飲酒會產生曲線效應。

One drink per day or less than seven drinks a week had a lower prevalence of erectile dysfunction compared to non-drinkers.

與不喝酒的人相比，每天喝一杯或每週少於七杯的人勃起功能障礙的發病率較低。

This may be linked to alcohol's positive impact on the psychological aspects of erectile dysfunction.

這可能與酒精對勃起功能障礙心理方面的積極影響有關。

So now let's talk about the elephant in the room.

現在，讓我們來談談房間裡的大象。

The other reason why people are getting erectile dysfunction at younger age is due to psychological issues.

人們年紀輕輕就患上勃起功能障礙的另一個原因是心理問題。

Psychological ED is more common in younger men.

Usually these men are able to get erections in the morning, they can get self-stimulated erections throughout the day, and even get erections at the beginning of sexual intercourse with a partner.

通常，這些男性能夠在早晨勃起，他們可以在一整天中自我刺激勃起，甚至在與伴侶開始性交時勃起。

But the issues come when having to maintain that erection throughout the duration of sex.

但是，如果要在整個性愛過程中保持勃起，問題就來了。

Essentially psychological ED is more likely to occur when you can get an erection at the start of sex with a partner, but it goes away and you can't get it back.

從根本上說，當您在與伴侶開始性生活時可以勃起，但勃起後又無法恢復時，就更有可能出現心理性 ED。

Most psychological ED cases are attributed to anxiety or depression and the psychological etiology that comes with both.

大多數心理性 ED 病例都歸因於焦慮或抑鬱，以及這兩種情況帶來的心理病因。

It is likely that the stress from anxiety and depression raises cortisol levels, increasing vascular resistance, and leading to erectile dysfunction in this younger population.

焦慮和抑鬱帶來的壓力很可能會提高皮質醇水準，增加血管阻力，導致這些年輕人出現勃起功能障礙。

There also could be other reasons as well.

Some researchers trace the pattern of increased erectile dysfunction since the 1990s to the increased use and access to pornography online since the 1990s as well.

一些研究人員認為，自 20 世紀 90 年代以來勃起功能障礙增加的模式，也是由於自 20 世紀 90 年代以來人們越來越多地使用和接觸網上色情製品造成的。

One paper from 2015 found erectile problems may occur when real life sexual stimulation does not match the broad visual sexual stimuli of online pornography.

2015 年的一篇論文發現，當現實生活中的性刺激與網絡色情中廣泛的視覺性刺激不一致時，可能會出現勃起問題。

Essentially when porn becomes your main source of sexual stimulation, when you end up having sex with someone in real life, you're not able to maintain an erection because it doesn't match your normal sexual stimuli.

從根本上說，當色情片成為你的主要性刺激來源時，當你在現實生活中與某人發生性關係時，你就無法保持勃起，因為這與你正常的性刺激不符。

A study in China also found that early porn use was associated with changes in reproductive hormone levels and semen quality.

中國的一項研究還發現，過早使用色情片與生殖激素水平和精液品質的變化有關。

There's a lot of other psychological studies, less like hard science studies, about the impacts of culture, the internet, social media on young people's ability to feel validated and sexually fulfilled.

關於文化、互聯網、社交媒體對年輕人獲得認同感和性滿足能力的影響，還有很多其他的心理學研究，不像是硬科學研究。

That's a much more complicated psychological concept.

這是一個複雜得多的心理學概念。

You can go to our podcast, Side Note by AsapSCIENCE, to see our episodes more on that.

您可以訪問我們的播客 "AsapSCIENCE的側記"，查看更多相關內容。

But it turns out that cohabiting with a partner is actually a good way to help with psychological ED.

但事實證明，與伴侶同居其實是一種有助於治療心理性 ED 的好方法。

The exact reasons are unsure, but one meta-analysis and large survey found that men who do not cohabitate with a romantic partner are more likely to have psychological ED.

確切的原因尚不清楚，但一項薈萃分析和大型調查發現，沒有與戀愛伴侶同居的男性更容易出現心理性 ED。

It's hard to read Nature magazine right now without reading about this increase in erectile dysfunction.

現在閱讀《自然》雜誌，很難不讀到有關勃起功能障礙增加的報道。

Also, as a millennial biker who slams my gooch all day, I really needed to understand that information.

此外，作為一個整天 "砰砰 "作響的 "千禧一代 "摩托車手，我真的需要了解這些資訊。

But this is important that we talk about this, this sexual health.

但我們必須討論這個問題，討論性健康。

It could be an awkward share, but also it doesn't have to be.

這可能是一次尷尬的分享，但也不必如此。

There's a lot more science happening right now in the realm of this area, so we'll make more videos as it comes in.

在這一領域，目前正在發生更多的科學事件，是以我們會在收到消息後製作更多視頻。
