1
Pornography use has increased every year since 1998.
2
Pornhub website visits have increased 11.6% since the pandemic,
3
making Pornhub the fourth most visited website next to Google, Facebook, and YouTube.
4
Maybe even more shockingly, when you put all porn websites together,
5
they get more visits than Twitter, Amazon, and Netflix combined.
6
At the same time, since the 1990s,
7
there's been an increase in male erectile dysfunction,
8
leading to what some researchers are calling is a crisis in male sexuality.
9
Is male erectile dysfunction and pornography use linked?
10
A recent study found that 82% of people who tried to quit watching pornography failed.
11
So what is porn doing to your brain?
12
Is it making young men unable to get hard?
13
And how can you tell if you or someone you know has a problem with porn?
14
Today we're gonna learn about the updated science on pornography use.
15
It's honestly intense.
16
Wanting to watch porn is related to dopamine,
17
a molecule you've heard a lot about here at ASAP Science
18
as it's involved with you physiologically craving the things you need to survive,
19
like money, food, love, friendship,
20
but importantly in the case of porn,
21
the molecule is involved with our physiological craving of novel experiences and sex.
22
The thing about scrolling porn websites is you're constantly looking at novel videos about sexual stimulation,
23
and this really impacts your meso-lymbic dopamine system.
24
Keeping tabs open
25
and scrolling porn sites actually physically changes the ventral striatum of your brain with two studies finding
26
that your ventral striatum physically grows due to watching porn websites.
27
And it is this physical change in your brain
28
that can over time make it harder for you to restrain from watching porn and even succumbing to dopamine cravings in general.
29
Essentially watching new novel sexual porn videos on websites is such an intense stimulus for your brain that it changes neural connections.
30
The areas in your brain that end up affected by watching porn are related to reward processing,
31
decision making, and emotional regulation.
32
One study found higher amounts of porn use is associated with preferring short-term gains over long-term gains.
33
While other studies show that the change in brain shape from increased porn consumption can lead to irritability,
34
depression, and lower self-esteem.
35
A lot of these physiological responses in your brain might lead you to think that pornography is addictive,
36
but that's still quite a controversial term within the science community.
37
Right now, something known as problematic porn use is considered an impulse control disorder,
38
but pornography addiction does not have a standalone diagnosis.
39
So how can you tell if you or someone you know has problematic porn use?
40
Here is a clear list.
41
Salience, you place pornography watching of high importance in your life.
42
Maybe you stay up extra late to watch it or find that you are prioritizing porn over sleep,
43
hanging out with friends or doing your work.
44
Mood modification, you use pornography to deal with negative emotions.
45
Tolerance, you gradually seem to need more and more pornography to feel satisfaction
46
or are watching more extreme pornographic imagery in order to feel satisfied.
47
Conflict, you have intra or interpersonal problems due to your pornography use.
48
Withdrawal, you feel psychological distress or withdrawal symptoms in the absence of pornography use.
49
And relapse, you experience unsuccessful efforts to reduce or stop pornography use.
50
In the general population of Australia,
51
North America, and Europe, approximately 70 to 94% of adults report lifetime pornography use.
52
Another study listed the countries with the highest number of people with problematic porn use,
53
which was Brazil at number five,
54
number four was Turkey, number three was Malaysia,
55
number two was China, and number one was Taiwan.
56
The thing is that in these studies,
57
you need to self-identify as having problematic porn use in order to show up in the research.
58
Many people probably have it,
59
don't want to admit it,
60
and even in these studies,
61
the results could be skewed.
62
One study found that in general,
63
seven percent of porn users feel they have a problem or self-proclaim that they are quote unquote addicted,
64
but as high as 32% in another study admitted that they wanted help with their pornography use.
65
Now, when it comes to pornography use and erectile dysfunction,
66
the new science coming in right now is fascinating.
67
In recent years, there has been a sharp increase in the prevalence of erectile dysfunction
68
and low sexual desire in men under the age of 40.
69
In a study conducted in Europe in 1999,
70
the erectile dysfunction and low sexual desire rate was 5%.
71
In 2011, ED rates increased to 14 to 28%.
72
Another survey of men under 40 in the US found that 34% claimed to have ED or low sexual desire.
73
This has led some researchers to trace the pattern of increased
74
erectile dysfunction to the increase in pornography access we have had since the 1990s.
75
One paper from 2015 found erectile problems may occur
76
when real-life sexual stimulation does not match the broad visual sexual stimuli of online pornography.
77
In other words, because porn is so prevalent and people might be using it as their main source of sexual stimuli,
78
when they're in the bedroom with someone else,
79
they have a harder time maintaining arousal or staying erect because it's not matching what they're used to doing.
80
A study in China found early porn use was associated with changes in reproductive hormone levels and semen quality.
81
Of course, there could be other reasons for the increase in male erectile dysfunction,
82
stress, world issues, even social media access online,
83
but researchers are not ruling out the trend of increased porn consumption as having an impact on increased male erectile dysfunction.
84
Now, when it comes to having problematic porn use,
85
it's important that you understand that you or the person you know who has it,
86
it's not your fault.
87
Pornography is considered a super normal stimulus and it's new for our brains to have to deal with looking at this content,
88
let alone being on Instagram where you're being fed soft core porn like all the time.
89
We are in an unprecedented time for sexual content on our phones,
90
through social media, and our brains have not adapted to deal with this type of stimulation.
91
In some cases, studies found porn consumption is used to deal with depressive symptoms,
92
loneliness, or even a fear of death.
93
That being said, the increased porn use didn't help these symptoms and ended up negatively affecting people's emotional moods.
94
Three studies I read were on the psychological effects of increased porn use.
95
It can lead to low mood,
96
depression, decreased self-esteem, and in extreme cases, decreases in appetite.
97
People with problematic porn use had increased rates of general anxiety,
98
psychological distress, and decreased bonding with family.
99
It's also important to reflect on when you started to watch porn because the younger you were watching porn,
100
the more impact it has on your brain and the harder it can be to stop watching porn.
101
So what can you do to deal with this?
102
One thing that's really important is to not blame yourself.
103
Again, this is a technological issue.
104
In fact, when you feel guilty about porn use,
105
it can backfire and make you actually consume porn more often.
106
One study on moral incongruence found
107
that being religious is a better predictor of porn-related problems than the actual amount of porn you are watching.
108
This is because of guilt.
109
The guilt of being religious and watching porn may actually lead you to seek it out.
110
Guilt or forced abstinence creates a reward prediction error where your brain has a hard time not focusing on not watching porn,
111
which in a backwards way makes you think about it more.
112
Intrusive negative thoughts can actually end up leading to arousal.
113
The clearest way I found to deal with your porn use was from a study using a diagram with these three words.
114
Liking, wanting, and needing.
115
Ideally, when viewing porn, you want to like it.
116
When the dopamine system in your brain starts to lean towards the area of wanting it,
117
or in extreme cases, needing it,
118
this is when you may need to seek help.
119
Another study on porn use found that the more people watched it,
120
the less they actually liked it.
121
This makes sense when looking at the diagram from this study.
122
When you get towards wanting or needing porn,
123
the reward strength actually decreases.
124
Most of these studies talk about the importance of cognitive behavioral therapy.
125
So if you feel like in your life,
126
you're getting to the point where you are wanting porn or needing porn,
127
then that's when you might need to seek out mental professional help.
128
There is a lot of studies coming out about this right now.
129
We're in unprecedented technological times as we've talked about for pornography access and use.
130
Share this video.
131
It might be an awkward share,
132
but share it with anyone who you think might be struggling with problematic porn use.
133
And make sure you're subscribed for more science videos.
134
We will continue to update you on the science as it comes in.
135
Like, subscribe, the classics, and we'll see you soon for a new video.
136
I'll say peace.

練習建議
在觀看這段影片時，您可以利用shadow speaks的技巧來提高您的英語發音。影片中的內容速度適中，語音清晰，非常適合進行影子跟讀練習。您可以先完整聽一遍，集中注意力在內容理解上；然後，在第二遍時，試著跟隨影片中發言的節奏進行shadow speech。這不僅可以提高您的發音，還能幫助您在雅思口語練習中更自信地表達觀點。
此外，請注意語調和重音，模仿影片中講話者的情感表達將有助於您更自然地掌握語言技巧。通過這種方式，您會更加熟悉如何在真實對話中使用這些詞彙，尤其是在討論如心理健康和人際關係等複雜話題時。
影片中的語法
說話人最常用的結構，並附上影片中的原話：
| 結構 | 影片中的用法 |
|---|---|
| 現在完成時 have/has + 過去分詞 — 過去發生但與現在仍有關聯的事 | has increased · have increased · there's been |
| 被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的 | is involved · is associated · is considered |
| 定語從句 who / which + 從句 — 補充說明人或事物 | people who tried · anyone who you |
什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
