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.


Sperm are at no time stored in the seminal vesicles. This information is completely inaccurate. Sperm is stored in the epididymis. Sperm only leave the epididymis during the process of ejaculation by ascending up the vas deferens before then mixing with seminal fluid released from the seminal vesicles. At no stage does sperm enter the seminal vesicles.

Since sperm is absorbed by the body, what is the connection between unejaculated sperm and prostate cancer?

there is no connection between unejaculated sperm and prostate cancer.


What happens when a man does not release sperm after sex? What do this mean.? Is it unheatlhly for him?

What happen to the testes if you are keeping out of your sperm cell ....what happen to the testes the tester become what bigger or not affected by doing ejaculation

I don't think that is correct. I believe sperm are stored in the epididymis until the ejaculation process begins. The seminal vesicle produces (some of) the seminal fluid that combines with the sperm to transport it out of the body. Perhaps a small amount of sperm are stored there, but certainly not the majority of it.

Thank you very much

What happens if we do not release sperm daily ...Does it cause harm, or good?

Sperm that are not ejaculated are resorbed (broken down) within the testes and seminal vesicles. No harm arises through this happening.

Is sperm release only during sex

Phew glad to hear that, as Ive had my prostate removed I dont ejaculate. I still produce sperm though and can orgasm, but no 'mess' I guess lol

Why after not releasing sperm for period of time does it turn brown?

It'll make it's own way out, either tacked onto the end of a piss or when you sleep. Your epididymis can store about a weeks worth of production, anything else comes out the same hole it normally does, just in smaller volume.

I have had a vasectomy with no trouble for five years gradually I have began to experience pain in the build up to evacuation then pulsing pain after sex. Over the past five months this has led to me being less inclined to have sex; sometimes it's so severe that I am curled up in pain from my lower abdomen for four about five minutes. I've been examined and was told not urgent and to wait for a scan... I am frightend I am not being taken seriously. I need this reversed urgently and am considering legal action, please can you help?

No offense buy why in God's name would a man do that to himself? For fear of having children? Makes no sense to me, man.

To answer your question, because vasectomy is one form of contraception and it suits some people. There are no known long term health risks associated with the procedure.
