Q & A

How many sperm cells are produced by the testes each day?

The testes produce about 300 million sperm cells per day.

What is the purpose of the Blood-Testis Barrier?

The Blood-Testis Barrier isolates developing sperm cells from the immune system to prevent them from being recognized as foreign and destroyed by immune cells.

Where are sperm cells stored after they are produced?

Sperm cells are stored in the Epididymis, specifically in a coiled tube called the Ductus Epididymis, which can be up to six meters long when straightened.

What happens to sperm cells if they are not released through ejaculation?

If sperm cells are not released, they eventually break down or degenerate and are reabsorbed by other cells lining the epididymis.

How does the body handle an accumulation of sperm cells in the epididymis?

The body reabsorbs older sperm cells as new ones are produced, preventing the epididymis from becoming overfilled.

What is the Prostate Stagnation Hypothesis?

The Prostate Stagnation Hypothesis suggests that an accumulation of prostatic secretions could potentially become carcinogenic, creating more opportunities for the development of prostate cancer.

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

The study found that a high frequency of ejaculation (21 or more times per month) correlated with about a 20% risk reduction in prostate cancer compared to a lower frequency (four to seven times per month).

What is the significance of the Australian study mentioned in the script?

The Australian study found that men who averaged 4.6 to 7 times per week of ejaculation were less likely to be diagnosed with prostate cancer before the age of 70 compared to those averaging about 2.3 times per week.

What should be considered when interpreting the studies on ejaculation frequency and prostate cancer risk?

It's important to consider that these studies looked at risk reduction for low-risk prostate cancer and did not include higher risk or more aggressive types. Additionally, potential errors in self-reporting and the need for more research should be taken into account.

What is the conclusion about the relationship between ejaculation frequency and prostate cancer risk based on the script?

While there is some evidence suggesting a correlation between higher ejaculation frequency and reduced risk of prostate cancer, it's not definitive, and more research is needed to establish a clear recommendation.

How does the script suggest we should approach the information about ejaculation frequency and health benefits?

The script suggests that while striving for a high frequency of ejaculation might not be necessary for everyone, it doesn't seem to hurt and could have other health benefits, especially when shared with a loved one.

Keywords

💡Sperm cells

Sperm cells are the male reproductive cells responsible for fertilization. In the video, it is mentioned that the testes produce millions of sperm cells daily, highlighting the high efficiency of sperm production. The script uses the term to discuss the process of spermatogenesis and the potential health implications of sperm cell accumulation or release.

💡Testes

The testes, often referred to as testicles, are male reproductive organs that produce sperm and hormones. The video script discusses the production of sperm cells in the testes, emphasizing the role of these organs in male fertility and the potential for sperm cell buildup if not regularly released.

💡Seminiferous tubules

Seminiferous tubules are the coiled tubes within the testes where sperm cells are produced. The video script describes these tubules as the site of sperm cell generation, with an average production rate of 3500 sperm cells per second, illustrating the intricate process of spermatogenesis.

💡Blood-Testis Barrier

The Blood-Testis Barrier is a selective barrier that separates the developing sperm cells from the immune system within the testes. The video explains its function to prevent the immune system from attacking the sperm cells, which are seen as foreign, thus protecting them during development.

💡Epididymis

The epididymis is a structure attached to the backside of each testis where sperm cells mature and are stored before ejaculation. The video script uses the term to answer the question of where the sperm cells go, explaining that the epididymis can store a large number of sperm cells due to its long, coiled duct.

💡Ductus Epididymis

The Ductus Epididymis is the coiled tube inside the epididymis where sperm cells are stored and mature. The video script mentions that if straightened out, this duct could be up to 20 feet long, emphasizing the capacity for sperm storage.

💡Vas Deferens

The Vas Deferens is a tube that transports sperm from the epididymis during ejaculation. The video discusses the procedure of vasectomy, where this tube is cut to prevent sperm from being released during climax, but other seminal fluids still are, illustrating the separation of sperm from other ejaculate components.

💡Prostate cancer

Prostate cancer is a type of cancer that affects the prostate gland in men. The video script explores the hypothesis that frequent ejaculation might reduce the risk of prostate cancer by preventing the buildup of potentially carcinogenic prostatic secretions, thus lowering the chance of developing the disease.

💡Prostate Stagnation Hypothesis

The Prostate Stagnation Hypothesis is a theory discussed in the video that suggests an accumulation of prostatic secretions could potentially become carcinogenic, thus increasing the risk of prostate cancer. The script presents studies that hint at a correlation between frequent ejaculation and reduced prostate cancer risk.

💡Ejaculation

Ejaculation is the process of expelling semen from the male body, which includes sperm cells and other seminal fluids. The video script discusses the frequency of ejaculation in relation to potential health benefits, such as a reduced risk of prostate cancer, and the natural process of sperm cell reabsorption if not ejaculated.

Highlights

The testes produce millions of sperm cells daily, averaging about 300 million.

In the time since the video started, a male with two functioning testes could have produced 50,000 to 70,000 sperm cells.

Sperm cells are produced in seminiferous tubules within the testes.

The average production rate is nearly 3,500 sperm cells per second.

The Blood-Testis Barrier isolates developing sperm cells from the immune system to prevent them from being recognized as foreign.

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

The epididymis can store a vast number of sperm cells, but there is a theoretical limit to its capacity.

Sperm cells that remain in the epididymis for too long begin to break down and are reabsorbed.

After a vasectomy, the absence of sperm cells in ejaculate is due to the cutting of the Vas Deferens, but other secretions continue as normal.

Frequent ejaculation may have potential health benefits, such as a reduced risk of prostate cancer.

A study followed 30,000 men and found a 20% reduction in prostate cancer risk with high-frequency ejaculation.

High frequency is defined as 21 or more ejaculations per month, while low frequency is about four to seven times per month.

Another study in Australia found similar results, with higher frequencies of ejaculation correlating to lower prostate cancer risk.

The studies included all types of ejaculations, such as intercourse, self, and nocturnal emissions.

While the studies suggest a benefit to frequent ejaculation, more research is needed for a definitive recommendation.

The potential reduction in cancer risk is for low-risk prostate cancer and does not account for more aggressive forms.

The video concludes by suggesting that while striving for high ejaculation frequency may not be necessary, it does not seem to hurt and could have additional benefits.

Transcripts

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.

[Intro]

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 testis called Seminiferous

Tubules.

Here's a right testis or 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 testis?

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 testis?

Well, there's also a Blood-Testis 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 the structure on the backside of each testis called the Epididymis and there

is a coil tube inside the epididymis called the Ductus Epididymis and if this were straightened

out, it would be up to six meters or about 20 feet long and this is where sperm are stored

and mature prior to being 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 20-foot 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

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 epididymal sperm population in

half but it's a lot more simple than that.

As sperm stay longer and longer in the epididymis, they start to break down or degenerate and

get reabsorbed by other cells lining the epididymis.

So, as new sperm cells are being produced each day, older sperm cells are also being

reabsorbed.

Now, this also explains what after the male birth control procedure called the Vasectomy.

A tube that is located after the epididymis known as the Vas Deferens is cut so that sperm

cells cannot exit.

But during male climax, secretions from the prostate, seminal glands, and bulbourethral

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 epididymis, 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."

but before we see if there's any truth to cancer risk reduction, I want to talk about

something else to help us with our health and that is saying thank you to the sponsor

today's video, AG1.

AG1 is a foundational nutrition supplement that I've been drinking every day for years

now.

It's made with 75 high-quality whole-food sourced ingredients including vitamins, minerals,

superfoods, probiotics, and adaptogens.

This is a formulation based on the latest science that maintains the highest quality

of standards and speaking of standards, something that I really like about AG1 is that it is

NSF certified for sport, which means it's tested to ensure that what's on the label

is actually in the bottle.

One of my other favorite benefits of AG1 is that it can help sustain energy levels throughout

the day and since I'm quite selective about my caffeine intake throughout the week, this

has been a definite bonus for me.

It's also ridiculously easy to make.

All you do is take one scoop, add eight ounces of water, shake it up, drink it down, and

carry on with your day and I really do believe the more that you can streamline and simplify

your health routine, the more likely you are to adhere to it and getting so many high-quality

ingredients in one easy scoop certainly helps one to streamline their routine.

So, if you're interested, go to drinkag1.com/humananatomy and they'll give our audience a free one-year

supply of immune-supporting vitamin D3+K2 as well as five free travel packets with your

first purchase.

We'll also include that information and the link in the description below.

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're 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 7 times per week were also less likely to be diagnosed with prostate

cancer before the age of 70 than those that only average 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 of the information we've discussed in this video so far?

Well, first we know, we don't have to worry about a build-up 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 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're 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 someone that you just love and adore with all of your anatomy.
