Summary

TLDR本视频脚本探讨了男性生殖系统的奥秘,特别是精子的生成和存储。男性每天可产生高达3亿精子,这些精子在附睾中成熟并储存。如果精子未被释放,它们会逐渐分解并被吸收。视频还讨论了频繁射精可能降低前列腺癌风险的假设,并引用了两项研究,其中一项发现每月21次以上的射精频率与降低20%的前列腺癌风险相关。尽管需要更多研究来确定这一关联,但视频以幽默的方式鼓励观众保持积极态度,并关注健康。

Takeaways

  • 😀 男性每天可以产生大约300万个精子。
  • 🙂 每秒钟大约产生3500个精子。

Q & A

  • 男性每天能产生多少精子细胞?

    -男性每天能产生大约3亿精子细胞。

  • 精子细胞是在哪个部位产生的?

    -精子细胞是在睾丸内的精原小管中产生的。

  • 什么是血睾屏障?

    -血睾屏障是一种屏障,它只允许某些物质从血液进入正在发育的精子细胞,以隔离精子细胞与免疫系统,防止免疫系统将精子细胞识别为外来物质。

  • 精子细胞成熟后储存在哪个结构中?

    -精子细胞成熟后储存在附睾中的附睾管里。

  • 附睾管如果伸直,大约有多长?

    -附睾管如果伸直,大约有6米或20英尺长。

  • 如果精子细胞没有被释放,会发生什么?

    -如果精子细胞没有被释放,它们会在附睾管中逐渐分解或退化,并被其他细胞重新吸收。

  • 男性结扎后,射精液中是否还有精子细胞?

    -男性结扎后,射精液中将不含有精子细胞,但仍然会有前列腺和精囊腺分泌的液体。

  • 频繁的射精是否可能降低前列腺癌的风险?

    -有研究表明,频繁的射精可能与降低前列腺癌的风险有关,但还需要更多的研究来确定这一联系。

  • 前列腺分泌物积累过多可能会怎样?

    -有假设认为前列腺分泌物积累过多可能会变得致癌,从而增加前列腺癌的风险,这有时被称为前列腺停滞假说。

  • 有研究显示,射精频率与前列腺癌风险之间的关系是怎样的?

    -一项研究显示,每月射精21次或以上的频率与较低的前列腺癌风险相关,而另一项研究也发现每周4.6至7次的频率同样与较低的前列腺癌风险相关。

  • 根据视频内容,我们应该如何理解射精频率与健康的关系?

    -虽然有研究表明射精频率可能与降低前列腺癌风险有关,但我们还需要更多的研究来重复这些结果。此外,这些研究考虑的是低风险前列腺癌,并不包括更高风险或更侵袭性的前列腺癌。

😲 男性生殖系统与精子生产

本段视频脚本介绍了男性生殖系统的基本工作原理,特别是睾丸如何每天产生数百万精子细胞。提到了精子是在称为精小管的微小管中产生的,并解释了精子如何在附睾中储存和成熟。还提到了血睾屏障,这是一种保护正在发育的精子细胞免受免疫系统攻击的机制。此外,讨论了如果精子不被释放,它们在附睾中如何被分解和重新吸收,以及这与男性避孕手术——输精管结扎术的联系。

05:00

🧐 射精频率与前列腺癌风险

第二段内容探讨了射精频率与前列腺癌风险之间的关系。介绍了所谓的前列腺停滞假说,即前列腺分泌物的积累可能成为致癌物质,从而增加前列腺癌的风险。引用了两项研究,一项研究了约30,000名46至81岁男性的射精频率,发现高频率射精与较低的前列腺癌风险相关;另一项较小规模的澳大利亚研究也得出了类似的结果。视频强调了这些研究的局限性,并建议在得出明确结论前需要更多的研究数据。最后,视频以幽默的方式鼓励观众根据自己的情况和喜好来决定射精频率。

Highlights

男性每天产生大约3亿精子细胞,每秒钟大约产生3500个。

精子细胞在睾丸中的精曲小管中产生。

存在血睾屏障,以保护精子细胞免受免疫系统的攻击。

精子在附睾中存储和成熟,附睾中的导管伸直可达20英尺长。

如果精子不被释放,它们会在附睾中分解并被其他细胞吸收。

输精管结扎术切断了输精管,阻止精子细胞排出,但不影响前列腺液的释放。

有假设认为前列腺液的积累可能与前列腺癌的发展有关。

一项研究显示,年轻时频繁的射精与前列腺癌风险降低20%有关。

高频率射精定义为每月21次或更多。

另一项澳大利亚的研究也得出了类似的结果。

研究包括性交、自慰和夜间射精在内的所有射精次数。

目前的研究结果并不意味着每个人都需要达到每月21次的射精频率。

研究结果可能存在自我报告的误差,并且需要更多的研究来重复这些发现。

尽管如此,频繁的射精似乎不会造成伤害,并且可能还有其他健康益处。

视频最后鼓励观众分享他们对讨论数字的看法。

Transcripts

play00:00

so the testes produce a lot of sperm

play00:02

cells each day we are talking Millions

play00:04

per day like about 300 million which

play00:07

means if you are a male that has two

play00:09

functioning testes just since this video

play00:11

started you've potentially produced

play00:13

anywhere from 50 to 70,000 sperm cells

play00:16

so where do they all go how do you keep

play00:19

up with such efficient production is

play00:21

there a problem if sperm cells aren't

play00:23

released and of course one of the more

play00:25

interesting questions are there any

play00:27

potential health benefits like reduction

play00:29

in cancer risk from more frequent

play00:31

release of sperm or other reproductive

play00:34

substances these are obviously very

play00:36

important questions that nearly every

play00:38

human male has likely wondered so of

play00:40

course we are going to answer these

play00:41

questions in the name of science so

play00:44

let's do

play00:51

this so just in case you've missed some

play00:53

of our previous male reproduction videos

play00:55

or just need a quick review sperm cells

play00:57

are produced in tiny tubes in each tesus

play01:00

called seminiferous tubules here's a

play01:02

right test or a testicle and if you open

play01:04

it up you can see these string-like

play01:06

seminiferous tubules and again if you

play01:09

average out 300 million per day that is

play01:11

nearly 3500 sperm cells being produced

play01:14

per second but can we also mention

play01:17

another really cool random fact about

play01:19

the testes have you ever heard of the

play01:21

blood brain barrier this is a barrier

play01:23

that only allows certain substances to

play01:26

pass from the blood and into the brain

play01:28

essentially creating this protective

play01:30

filter for the delicate nervous tissue

play01:32

so what does this have to do with the

play01:34

testes well there's also a blood testos

play01:37

barrier now this isn't actually a

play01:39

barrier of blood for the whole testis

play01:41

but just a barrier between the blood and

play01:43

the developing sperm cells the main

play01:45

reason for this is to isolate the sperm

play01:48

cells from the immune system because the

play01:50

sperm cells are actually recognized as

play01:52

foreign to our immune cells so we want

play01:55

to prevent these developing sperm cells

play01:57

from being gobbled up now once the sperm

play01:59

are produced by these seminiferous

play02:00

tubules they are eventually moved into

play02:02

this structure On The Backs side of each

play02:05

tesus called the epidemis and there's a

play02:07

coil tube inside the epidemis called the

play02:09

ductus epidemis and If This Were

play02:12

straightened out it would be up to 6 M

play02:14

or about 20 ft long and this is where

play02:17

sperm are stored and mature prior to

play02:19

being released from the body and this

play02:21

answers the question where do they all

play02:24

go because you can store a lot of

play02:26

microscopic sperm cells in a 20 foot

play02:28

long tube however there are still

play02:30

potential limitations to a 20ft long

play02:32

tube and in theory you could eventually

play02:35

fill this completely up with sperm cells

play02:37

if ejaculation were to never take place

play02:40

or if there was not some other way to

play02:42

deal with sperm that was not released

play02:44

now I would love to tell you some epic

play02:46

story that when there are too many sperm

play02:48

cells they go to war with one another

play02:51

and it's the X sperm cells versus the Y

play02:53

sperm cells strangling each other with

play02:55

their tails and eventually cutting the

play02:57

epid sperm population in half but it's a

play03:00

lot more simple than that as sperms stay

play03:03

longer and longer in the epidemis they

play03:06

start to break down or degenerate and

play03:08

get reabsorbed by other cells lining the

play03:11

epidemis so as new sperm cells are being

play03:13

produced each day older sperm cells are

play03:16

also being reabsorbed now this also

play03:18

explains what happens after the male

play03:20

birth control procedure called the

play03:21

vasectomy a tube that is located after

play03:24

the epidemis known as the vast Defence

play03:27

is cut so that sperm cells cannot exit

play03:30

but during male climax secretions from

play03:32

the prostate seminal glands and bubble

play03:34

urethal glands are still released and to

play03:37

the naked eye would pretty much look

play03:38

identical but under the microscope you

play03:40

would see that it contains no sperm

play03:42

cells so again because sperm cells can

play03:45

be broken down and reabsorbed in the

play03:47

epidemis if they are not released it

play03:50

shouldn't be much of a problem but could

play03:53

there be other potential benefits to

play03:55

consistent or frequent ejaculation like

play03:58

a potential reduction in prostate cancer

play04:00

risk now I can just see all the males

play04:03

out there getting ready to approach

play04:05

their significant other and say as

play04:07

romantically as possible hey it's cancer

play04:10

risk reduction time so is there any

play04:13

reason to have more frequent

play04:15

ejaculations specifically could there be

play04:17

a potential reduction in the risk of

play04:19

prostate cancer which affects about one

play04:21

in eight men during their lifetime and

play04:23

if there is a risk reduction what is

play04:26

this potential correlation between

play04:28

prostate cancer risk and the frequency

play04:30

of ejaculation well earlier I mentioned

play04:32

that the prostate produces secretions

play04:34

that make up part of the ejaculate and

play04:36

these prostatic secretions help to

play04:38

protect and nourish the sperm cells but

play04:41

there is a hypothesis that if there's an

play04:43

accumulation or a buildup of prostatic

play04:46

secretions maybe some of this excess

play04:48

could potentially become carcinogenic

play04:50

thereby creating more opportunity for

play04:52

the development of prostate cancer and

play04:54

this is sometimes referred to as the

play04:56

prostate stagnation hypothesis now to be

play05:00

clear there are multiple factors that

play05:02

contribute to the development of

play05:03

prostate cancer other than just the

play05:05

frequency of ejaculation and a possible

play05:08

prostate stagnation hypothesis but there

play05:11

are two very interesting studies that I

play05:13

think most males will think to be quite

play05:15

positive the first and one of the most

play05:18

prominent studies in this area followed

play05:20

about 30,000 men between the ages of 46

play05:23

and 81 and they looked at their average

play05:25

number of ejaculations per month when

play05:27

they were in their young adulthood years

play05:29

like ages 20 to 29 when they are in

play05:31

middle age ages 40 to 49 and even in

play05:34

more their more recent years and what

play05:36

they found was that a high frequency of

play05:38

ejaculation correlated with about a 20%

play05:41

risk reduction in prostate cancer when

play05:44

compared to the lower frequency of

play05:46

ejaculation now of course everyone is

play05:49

probably wondering what's considered

play05:50

high frequency versus low frequency what

play05:53

does this mean well high frequency was

play05:55

21 or more times per month that's quite

play05:59

the active bunch of individuals whereas

play06:01

low frequency was about four to seven

play06:03

times per month another study in

play06:05

Australia found similar results although

play06:07

this was a much smaller group of just

play06:09

over 2300 men but it found that men who

play06:12

averaged 4.6 to seven times per week

play06:15

were also less likely to be diagnosed

play06:17

with prostate cancer before the age of

play06:19

70 than those that only averaged about

play06:21

2.3 times per week and this effect

play06:24

appeared to be the strongest if the high

play06:26

frequency occurred more in young

play06:27

adulthood now one last thing I do want

play06:29

to clarify is that these studies counted

play06:31

the total number of ejaculations whether

play06:34

it was intercourse self or nocturnal

play06:36

emissions and let's be honest no one is

play06:39

really getting 21 nocturnal emissions or

play06:41

what we called freebies in my teenage

play06:43

years they're just not getting 21 of

play06:45

these per month but nonetheless they

play06:48

included any freebie or nocturnal

play06:50

emission in the totals so what should we

play06:53

do with all the information we've

play06:54

discussed in this video so far well

play06:57

first we know we don't have to worry

play06:59

about buildup of sperm cells because the

play07:01

body will just reabsorb those on its own

play07:03

but more importantly what should we do

play07:05

with this information about prostate

play07:08

cancer risk does this mean that everyone

play07:10

should just strive for 21 times a month

play07:13

or five times per week well there are a

play07:16

couple of things to consider one this

play07:18

was a risk reduction for low-risk

play07:20

prostate cancer this didn't include

play07:22

higher risk or more aggressive

play07:24

metastasizing prostate cancers and

play07:27

although the studies especially the

play07:28

first study were well done and tried to

play07:30

account for multiple variables you have

play07:33

to consider potential errors in

play07:34

self-reporting from the men recounting

play07:36

their ejaculation frequency and even

play07:39

there still just aren't a lot of

play07:40

research studies in this area so I do

play07:42

think it is hard to say that just

play07:44

everyone absolutely needs to strive for

play07:47

this magic number of 21 I think we still

play07:49

need more studies and data repeating

play07:51

these results before we can give a

play07:53

definitive answer like that but it

play07:55

definitely doesn't seem like it can hurt

play07:57

so if you already at 21 or more good for

play08:00

you if you want to strive for more to

play08:02

get closer to that 21 good luck in your

play08:04

journey and let's be honest there can be

play08:07

many other benefits if some of those 21

play08:10

come with the help of that special

play08:12

someone that you just love and adore

play08:14

play08:17

you got some fun information and useful
