【射精】男性的射精頻率：真的越高越好嗎？

Summary

This video script delves into male reproductive health, discussing the daily production of sperm cells, their storage in the epididymis, and the body's natural reabsorption process. It also explores the prostate stagnation hypothesis, which suggests a potential link between frequent ejaculation and reduced prostate cancer risk. Studies are cited that indicate higher ejaculation frequency in young adulthood may correlate with a lower risk of prostate cancer, though more research is needed for a definitive conclusion.

Takeaways

• 😲 The human male body produces millions of sperm cells daily, with an average of about 300 million, which equates to nearly 3500 sperm cells per second.
• 🔬 Sperm cells are produced in seminiferous tubules within the testes and are stored and mature in the epididymis, a structure that can hold a significant amount of sperm due to its length of about 20 feet when straightened out.
• 🛡️ The blood-testis barrier protects developing sperm from the immune system by isolating them, as sperm cells are recognized as foreign by the immune cells.
• 🧐 If sperm cells are not released through ejaculation, they do not accumulate indefinitely; instead, they break down and get reabsorbed by other cells in the epididymis.
• 💡 A vasectomy, a male birth control procedure, involves cutting the vas deferens, which prevents sperm from being released during climax, but other seminal secretions are still produced, making the ejaculate appear normal.
• 🧐 There is a hypothesis that frequent ejaculation might reduce the risk of prostate cancer by preventing the buildup of prostatic secretions that could potentially become carcinogenic, known as the prostate stagnation hypothesis.
• 📊 Studies have shown a correlation between higher frequency of ejaculation and a reduced risk of prostate cancer, with one study indicating a 20% risk reduction for those with 21 or more ejaculations per month compared to 4 to 7 times per month.
• 🌏 The findings from studies on ejaculation frequency and prostate cancer risk should be considered with caution, as they account for self-reported data and may not include all types of prostate cancer.
• 🤔 While the studies suggest potential benefits of frequent ejaculation, it is not definitive advice for everyone to aim for a specific number of ejaculations per month, and more research is needed.
• 💕 The video suggests that while the health implications are interesting, the emotional and relational aspects of sexual activity should also be considered, emphasizing the importance of love and connection.

Q & A

How many sperm cells are produced by the human body daily?

The human body produces approximately 300 million sperm cells daily.

How many sperm cells are produced per second on average?

On average, nearly 3500 sperm cells are produced per second.

What is the function of the blood-testis barrier?

The blood-testis barrier isolates developing sperm cells from the immune system to prevent the immune cells from recognizing and attacking the sperm cells as foreign.

Where are sperm cells stored and mature in the male reproductive system?

Sperm cells are stored and mature in the epididymis, specifically in the ductus epididymis, which can be up to 20 feet long when straightened out.

What happens to sperm cells that are not released through ejaculation?

Unreleased sperm cells stay in the epididymis, where they eventually break down or degenerate and get reabsorbed by other cells lining the epididymis.

What is the prostate stagnation hypothesis?

The prostate stagnation hypothesis is the idea that an accumulation or buildup of prostatic secretions could potentially become carcinogenic, thereby creating more opportunity for the development of prostate cancer.

What did the study involving about 30,000 men find regarding ejaculation frequency and prostate cancer risk?

The study found that a high frequency of ejaculation, defined as 21 or more times per month, correlated with about a 20% risk reduction in prostate cancer compared to lower frequencies of ejaculation.

What was the frequency of ejaculation considered 'high' in the Australian study?

In the Australian study, a high frequency of ejaculation was considered to be 4.6 to seven times per week.

How did the studies account for different types of ejaculation?

The studies counted the total number of ejaculations, including intercourse, self-ejaculation, and nocturnal emissions.

What are some limitations or considerations regarding the studies on ejaculation frequency and prostate cancer risk?

Limitations include potential errors in self-reporting from men recounting their ejaculation frequency, the fact that the studies did not include higher risk or more aggressive prostate cancers, and the need for more research to confirm the findings.

What is the conclusion or recommendation based on the information about ejaculation frequency and prostate cancer risk?

While the studies suggest a potential risk reduction with higher ejaculation frequency, it's recommended that more research is needed before giving a definitive answer. It doesn't seem to hurt to have a higher frequency, but individuals should consider their personal circumstances and health.

😲 Sperm Production and Storage Mechanisms

This paragraph delves into the astonishing daily sperm production by the human male testes, which can reach up to 300 million sperm cells. It explains the process of sperm cell development in seminiferous tubules and their storage in the epididymis, a coiled tube that can stretch up to 20 feet in length. The paragraph also touches on the blood-testis barrier, which isolates sperm from the immune system to prevent their destruction. Furthermore, it addresses the concern of what happens to sperm cells that are not released, revealing that older sperm cells break down and are reabsorbed, thus preventing overpopulation in the epididymis.

🤔 The Impact of Ejaculation Frequency on Prostate Cancer Risk

The second paragraph explores the potential health benefits of frequent ejaculation, particularly its correlation with a reduced risk of prostate cancer. It cites two studies that suggest a higher frequency of ejaculation, defined as 21 or more times per month during young adulthood, is associated with approximately a 20% decrease in prostate cancer risk. The summary also discusses the prostate stagnation hypothesis, which posits that an accumulation of prostatic secretions could potentially become carcinogenic. However, it cautions that these findings should be interpreted with consideration of other contributing factors to prostate cancer development, the limitations of self-reported data, and the need for further research before making definitive recommendations on ejaculation frequency.

Keywords

💡Sperm

Sperm are the male reproductive cells necessary for fertilization. In the video, it is mentioned that millions of sperm cells are produced daily, specifically around 300 million, highlighting the high efficiency of the male reproductive system. The script uses the term to discuss the production, storage, and potential health implications related to sperm.

💡Testes

The testes are the male organs responsible for producing sperm and hormones. The script explains that sperm cells are produced in the seminiferous tubules within the testes and that each male has two functioning testes, emphasizing their role in the reproductive process.

💡Seminiferous Tubules

Seminiferous tubules are the tiny tubes within the testes where sperm cells are produced. The video script describes them as string-like structures and provides an average number of sperm cells produced per second, illustrating their importance in sperm generation.

💡Epididymis

The epididymis is a structure on the backside of each testis where sperm cells are stored and mature before being released from the body. The script explains that the ductus epididymis inside the epididymis can be up to 20 feet long when straightened out, indicating its role in sperm storage.

💡Blood-Testis Barrier

The blood-testis barrier is a selective barrier that isolates developing sperm cells from the immune system. The video script mentions this barrier to explain why sperm cells are not recognized by the immune system, thus preventing them from being destroyed.

💡Degeneration

Degeneration refers to the process where older sperm cells break down and are reabsorbed by other cells in the epididymis. The script uses this term to explain what happens to sperm cells that are not released through ejaculation, indicating a natural mechanism of disposal.

💡Vasectomy

A vasectomy is a male birth control procedure where the vas deferens is cut to prevent sperm cells from exiting the body. The video script discusses the procedure to illustrate that even without sperm release, the body can still manage the absence of sperm through reabsorption.

💡Prostate Cancer

Prostate cancer is a type of cancer that affects the prostate gland in men. The script explores the hypothesis that frequent ejaculation might reduce the risk of prostate cancer by preventing the buildup of prostatic secretions, which could potentially become carcinogenic.

💡Ejaculation Frequency

Ejaculation frequency refers to how often a male ejaculates, which can be through intercourse, self-stimulation, or nocturnal emissions. The video script discusses studies that suggest a higher frequency of ejaculation may correlate with a reduced risk of prostate cancer.

💡Prostate Stagnation Hypothesis

The prostate stagnation hypothesis is a theory that suggests an accumulation of prostatic secretions could potentially lead to prostate cancer. The script mentions this hypothesis as a possible explanation for the correlation between ejaculation frequency and prostate cancer risk.

💡Nocturnal Emissions

Nocturnal emissions, also known as 'wet dreams,' are spontaneous ejaculations that occur during sleep. The video script includes these in the total count of ejaculations when discussing the potential health benefits of frequent ejaculation.

Transcripts

so the testes produce a lot of sperm

cells each day we are talking Millions

per day like about 300 million which

means if you are a male that has two

functioning testes just since this video

started you've potentially produced

anywhere from 50 to 70,000 sperm cells

so where do they all go how do you keep

up with such efficient production is

there a problem if sperm cells aren't

released and of course one of the more

interesting questions are there any

potential health benefits like reduction

in cancer risk from more frequent

release of sperm or other reproductive

substances these are obviously very

important questions that nearly every

human male has likely wondered so of

course we are going to answer these

questions in the name of science so

let's do

this so just in case you've missed some

of our previous male reproduction videos

or just need a quick review sperm cells

are produced in tiny tubes in each tesus

called seminiferous tubules here's a

right test or a testicle and if you open

it up you can see these string-like

seminiferous tubules and again if you

average out 300 million per day that is

nearly 3500 sperm cells being produced

per second but can we also mention

another really cool random fact about

the testes have you ever heard of the

blood brain barrier this is a barrier

that only allows certain substances to

pass from the blood and into the brain

essentially creating this protective

filter for the delicate nervous tissue

so what does this have to do with the

testes well there's also a blood testos

barrier now this isn't actually a

barrier of blood for the whole testis

but just a barrier between the blood and

the developing sperm cells the main

reason for this is to isolate the sperm

cells from the immune system because the

sperm cells are actually recognized as

foreign to our immune cells so we want

to prevent these developing sperm cells

from being gobbled up now once the sperm

are produced by these seminiferous

tubules they are eventually moved into

this structure On The Backs side of each

tesus called the epidemis and there's a

coil tube inside the epidemis called the

ductus epidemis and If This Were

straightened out it would be up to 6 M

or about 20 ft long and this is where

sperm are stored and mature prior to

being released from the body and this

answers the question where do they all

go because you can store a lot of

microscopic sperm cells in a 20 foot

long tube however there are still

potential limitations to a 20ft long

tube and in theory you could eventually

fill this completely up with sperm cells

if ejaculation were to never take place

or if there was not some other way to

deal with sperm that was not released

now I would love to tell you some epic

story that when there are too many sperm

cells they go to war with one another

and it's the X sperm cells versus the Y

sperm cells strangling each other with

their tails and eventually cutting the

epid sperm population in half but it's a

lot more simple than that as sperms stay

longer and longer in the epidemis they

start to break down or degenerate and

get reabsorbed by other cells lining the

epidemis so as new sperm cells are being

produced each day older sperm cells are

also being reabsorbed now this also

explains what happens after the male

birth control procedure called the

vasectomy a tube that is located after

the epidemis known as the vast Defence

is cut so that sperm cells cannot exit

but during male climax secretions from

the prostate seminal glands and bubble

urethal glands are still released and to

the naked eye would pretty much look

identical but under the microscope you

would see that it contains no sperm

cells so again because sperm cells can

be broken down and reabsorbed in the

epidemis if they are not released it

shouldn't be much of a problem but could

there be other potential benefits to

consistent or frequent ejaculation like

a potential reduction in prostate cancer

risk now I can just see all the males

out there getting ready to approach

their significant other and say as

romantically as possible hey it's cancer

risk reduction time so is there any

reason to have more frequent

ejaculations specifically could there be

a potential reduction in the risk of

prostate cancer which affects about one

in eight men during their lifetime and

if there is a risk reduction what is

this potential correlation between

prostate cancer risk and the frequency

of ejaculation well earlier I mentioned

that the prostate produces secretions

that make up part of the ejaculate and

these prostatic secretions help to

protect and nourish the sperm cells but

there is a hypothesis that if there's an

accumulation or a buildup of prostatic

secretions maybe some of this excess

could potentially become carcinogenic

thereby creating more opportunity for

the development of prostate cancer and

this is sometimes referred to as the

prostate stagnation hypothesis now to be

clear there are multiple factors that

contribute to the development of

prostate cancer other than just the

frequency of ejaculation and a possible

prostate stagnation hypothesis but there

are two very interesting studies that I

think most males will think to be quite

positive the first and one of the most

prominent studies in this area followed

about 30,000 men between the ages of 46

and 81 and they looked at their average

number of ejaculations per month when

they were in their young adulthood years

like ages 20 to 29 when they are in

middle age ages 40 to 49 and even in

more their more recent years and what

they found was that a high frequency of

ejaculation correlated with about a 20%

risk reduction in prostate cancer when

compared to the lower frequency of

ejaculation now of course everyone is

probably wondering what's considered

high frequency versus low frequency what

does this mean well high frequency was

21 or more times per month that's quite

the active bunch of individuals whereas

low frequency was about four to seven

times per month another study in

Australia found similar results although

this was a much smaller group of just

over 2300 men but it found that men who

averaged 4.6 to seven times per week

were also less likely to be diagnosed

with prostate cancer before the age of

70 than those that only averaged about

2.3 times per week and this effect

appeared to be the strongest if the high

frequency occurred more in young

adulthood now one last thing I do want

to clarify is that these studies counted

the total number of ejaculations whether

it was intercourse self or nocturnal

emissions and let's be honest no one is

really getting 21 nocturnal emissions or

what we called freebies in my teenage

years they're just not getting 21 of

these per month but nonetheless they

included any freebie or nocturnal

emission in the totals so what should we

do with all the information we've

discussed in this video so far well

first we know we don't have to worry

about buildup of sperm cells because the

body will just reabsorb those on its own

but more importantly what should we do

with this information about prostate

cancer risk does this mean that everyone

should just strive for 21 times a month

or five times per week well there are a

couple of things to consider one this

was a risk reduction for low-risk

prostate cancer this didn't include

higher risk or more aggressive

metastasizing prostate cancers and

although the studies especially the

first study were well done and tried to

account for multiple variables you have

to consider potential errors in

self-reporting from the men recounting

their ejaculation frequency and even

there still just aren't a lot of

research studies in this area so I do

think it is hard to say that just

everyone absolutely needs to strive for

this magic number of 21 I think we still

need more studies and data repeating

these results before we can give a

definitive answer like that but it

definitely doesn't seem like it can hurt

so if you already at 21 or more good for

you if you want to strive for more to

get closer to that 21 good luck in your

journey and let's be honest there can be

many other benefits if some of those 21
