【射精】男性的射精頻率:真的越高越好嗎?
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。

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。
Outlines
😲 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。
🧐 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。

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
come with the help of that special
