What happens to sperm that isn't ejaculated?

What happens to all the sperm that isn’t ejaculated, where does it go and is it still healthy?


Chris - This is a very good question; healthy testes make sperm at the rate of between 1000 and 5000 sperm cells per second. These collect in a long coil of tubes above and behind each testicle called the epididymis, where they are stored until needed. The testes hang external to the body within the scrotum to achieve an optimal temperature for sperm production. This is because sperm are made most efficiently at a slightly lower temperature than body temperature.

In the epididymis the sperm are nourished and make their way to the vas deferens, which is a muscular tube connecting the testis to the urethra up inside the male body. When sperm are ejaculated they are pushed along the vas deferens by rhythmic contractions of the musculature. Once inside the body, secretions from the prostate gland and seminal vesicles are added, producing the semen that is ejaculated from the penis. 

However, although they can survive there for quite a long period within the male anatomy, a fraction of the sperm that are made are never ejaculated. Instead, they will senesce and are broken down. And of course all the things that you take into your body, cigarette smoke, other toxins and things will damage the sperm potentially. So they have a sort of recycle time. And sperm that have reached their sell-by-date get broken down in the same way that, let's say, blood cells get broken down. And, basically, any of the nutrients and goodies in the sperm just get recycled back inside the body, and new sperm are produced to make up for the shortage.

Helen: - So it's a kind of continual, sort of, replacement, really...?

Chris: - Exactly. Those that don't leave the body eventually break down, and their components are recycled.


it will cause strain on your prostate, I know a lot of people do this like reaching a state of orgasm but stopping ejaculation but it causes strain on prostate and nervous system since your emotions send strong impulses to your body and your body starts preparing and u never ejaculate causing the process to b broken, it will also cause Headaches back pain due to stimulation of the nervous system and yeah u may feel weak in legs too.

I often masturbate for hours without releasing sperm. Does the recycled cum increase my testosterone?

No, because testosterone will already been in equilibrium between the seminal fluid and the body fluids, so there will be little net movement between the two.

No. Sitting around masturbating like a creep is decreasing your testosterone.

Does the DNA coding in recycled sperm account for abnormal birth defects if lets say a retarded sperm is broken down and then mixes with a normal sperm to create sperm that retarded and deformed?

Does masturbating help keep the chances of retarded sperm from mixing with normal sperm?

When sperm cells are recycled, like any recycled cell in the body, they are degraded completely, including their DNA, which is enzymically broken apart to its basic building blocks. So no vestige remains.

I had fracture approx 25days ago.since then I Did no have sex with my wife now since the last two days I am having erections during sleep and pressure in the groin I am 63 but still sexually and physically active my wife always tries to abstain from sex .what should I do now to relive the pressure in my groin at night.

Try jerking off before going to sleep.

u should meditate and calm mind before going to sleep this will help u relax body and mind u won't even get wet dreams much less erection.

I'm planning to do nofap in a weird way. One of the benefits of nofap is to assure that the sperm was absorbed back in the body, which is good because the body gets some nutrients. So the plan is, fap right after it was absorbed. By doing so, you have both your nutrients back and you are also decreasing the chance of getting prostate cancer. In other say, what's the optimal time to fap?

does reabsorption of sperm means use of it? does this retention increase our learning and reminding power

I want to point out something and everyone here is welcome to share their own thoughts... If one stops Sex or masturbation so as not to ejaculate the next problem is wet dream which is still ejaculation... so what is the solution? I wonder all these folks who are on nofap and those who don't marry if don't they have wet dream...I'm thinking having sex or masturbating without ejaculation might be better in the case of handling wet dream

You will get tension in the groin

just like commenter above me said "Having sex without ejaculating is the biggest mistake ever it causes pressure in groin" as for wet dream, meditate and calm/relax your mind before sleeping u wont have any if u are sufficiently relaxing.

Since I Started Having Sex, Sperm Never Come Out Of My Panis, Does It Mean Am Impotence Or Does Not Last For Time Needed...Please Advise Needed

To much sex can cause that problem all jokes aside.and there are men im guessing that might be choking their chicken a little much if you know what I mean without saying it the wrong way.but it's not uncommon

Young age may cause this, or too much ejaculation can also cause this. But usually you can cum once you reach age 12-14 ave. But it can take as long as 16-18 even. Ive heard of really late bloomers..(its not a big deal)..but otherwise you could ask a doctor..which wouldn’t be even close to an odd question compared to the things others asked doctors. (Trust me)

What are the effect or cause of low sperm counts?

I want to ask so something , I’m now 20 yo and i never beat my meat before and now when i try to nothing comes out shall i be scared or what should i do?

It was the same for me, first time definately took longer. No reason to be scared just keep at it with a fair amount of lube, spit or even better pre cum.

When i sleep i have sex dream but i got wet sperm when i wake up but if i sex in life i cant se any sperm when i unirate i get small sperm with red blood pleas what can i do

u should go see a doc.

Dear Doctor,

I am married, while doing sex during the time of ejection some 1/2 amount liquid will come out and 1/4th of liquid goes to upper right side kidney and 1/4th right leg nerve..
Kindly advice

Im sorry, but the amount and process of making that much sperm and prostatic fluids In now way is healthy! This Idiot female has not clue about any Male anatomy nor test results to speak of. No , its now Decided by most urologist that not ejaculating regularly can raise prostate cancer risk! its the function of all the glands that producing their parts of semen that do not halt because you stop ejaculating. that would be hard after a period of time anyway yet still the fluid doesnt just recycle. the old stagnating sperm and fluid rots as new is produced which is never good. Females Eggs and lining rot but they leave the body. Theres no recycling to decay!

Why would you call females idiots? Do you really think we are that we don't know what happens to the male body? You are the IDIOT if you think that!

I'm pretty sure he didn't call females idiot. He said, "idiot female," indicating that particular idiot was a female. In no way I believe he called all females idiots. He does seem pretty stupid but I don't think he's sexist. He just said that idiot which happens to be a female "has not clue" xD

Highlighting the word female when calling somebody an idiot indicates that The speaker considers Gender causative of the idiocy. It was insulting and the Female commenting deserves an apology.

It is right to think that females give birth to males. But there is no chance for a female knowing how a male feels inside the body when he is aroused. Because male body build is different from female. And in addition to that they cannot get the same feeling as male arousal is mainly bodily expression and female arousal is a kind of body and also mind . The feelings are different. Moreover a male gets arousal only if a female is attractive particularly to his taste regardless of whether a particular girl is beautful or not. Some girls are beautiful but not attractive. There is subtle differences between beauty, attraction, arousal.

So Chris...where does this recycle process take place and how?can you please ellabourate?

nice question .please answer

I want to know that when a man stopping the sperm by hand so it's going back to their position or not or it's harmful ,and the dopamine is going back to Brain or not

Hi Chris
I'm currently on a nofap journey and many people there in the forum are saying that you get so much energy and have much a healthier life if you don't ejaculate because your body can keep the energy and stuff from sperm which mean that you have a lot more energy for other things.
I really don't believe in that but I'm looking for evidence for on or the other opinion.
Can you reason why or why not the body can have (significant) more energy because of the recycling of sperm? How much energy does it really need to produce sperm? Is it that significant or is a small workout much more strenuous?
Is the body really releasing significant amounts of nutrients during ejaculation?

Don Juan in the Carlos Castenada books takes about the use of energy, and how it needs to be conserved in order to become a man of knowledge. The unique abilities achieved require vast amounts of energy. Creating life during sex is a bestowment of awareness in another being and is not to be taken lightly.

You’ve spoken some real words my man. We need more people like you.

Guys its a fact that approx 32 kgs of food makes 800grams blood and that 800 gm blood makes 20grams of sperm
Means masturbating destroys your energy a lot and if u stop ejaculating definitely you can live a healtheir life
Refer to the ancient indian ''brahmachari jeevan (life)" of those legends who never got married or ejaculate refer to the ancient knowledge of india and china

Can we see the published evidence to support that claim please?

Everything he said was stupid.

"its a fact that approx 32 kgs of food makes 800grams blood"

Because energy from food is measured in weight? So if i ate 32kg of chocolate id be the same as 32kg of apples?

Then he talks about some nonsense after

I just wanna have an erection at any time on n on and I know if I dont ejaculate I be able to do so that's why I wanna no if its harmful

i dont know if its recycled but let me tell u my experience, I was on treatment for tuberculosis for 9months and i was so fatigued(i didn't even have the energy to speak I spoke a lot less at that time and came off as an arrogant guy :P ) after treatment, i dont know why i started nofap may b just to try out, but at first i went 3 days then 8 days then relapsed then 10 days and then i felt my spine,and brain go warm and that warmth was bordering hot and i couldnt sleep at noon because of that ,persisted from day 8 and at 10th day i felt so good and relapsed but this relapse didnt cause much fatigue to me just some pressure on the back of my head but it really cleared my brainfog and fatigue (i won't say its fully gone but yeah i do feel physically stronger than that time)after that I m on off doing like 10 days-15 days and i do realize difference, i think my body is better absorbing nutrients than when i was fapping.

I thought sperm was stored in the epididymis, not in the seminal vesicle. Am I wrong?

you are right bro...no one else noticed the mistake

How many days it takes to recycle the not ejected semen

I once read that the lifetime of sperm is 10 days

But I have read that sperm live for only two days

when making love nd d man decide not to release a sperm what effect does it have?

I think the likely answer is "frustration", but it's not harmful...

How leave expired sperm from our body without sex or ejaculation.

From past two weeks I can't ejaculate . Semen goes to the bledder or testes instead of going out of penis. Is this normal ? How this can be treated?

Are you diabetic by chance? That happens sometimes to diabetics. Doesn't necrssarily mean you are, but you should check it out.

When a man ejaculate either by sex or masturbation dors there any mature sperm left behind in body after ejaculation? Can we go for conceive after ejaculation ? May be after a month or few weeks ?
