What Are Male Ejaculations: Everything You Need to Know

Reading time -

Male ejaculations are something that almost all men experience in their lifetimes. Nature's purpose of ejaculation is to transport sperm from the testes to the vagina to fertilize an egg. Though the process may seem simple, a lot goes into it.

Did you know that the prostate gland produces fluid that helps sperm travel and survive its journey to find an egg? A lot is going on under the hood to facilitate penis ejaculation, and it doesn't always run smoothly.

This article will discuss everything you need to know about male ejaculations!

What Is Male Ejaculation?

Ejaculation is an essential function in reproduction but not something everyone has a deep knowledge of. There's no real reason to question anything when things are working well. But as many men will know, male cumming is not always a guarantee. So what exactly is going on before and during an ejaculating penis?

Male ejaculation is the term given to the act of expelling semen out of the penis. It typically accompanies the male orgasm but can happen on its own. The semen contains sperm, a sticky white fluid that can fertilize an egg, leading to fertilization.

In some instances, such as erectile dysfunction or delayed or absent ejaculation, something stops the penis ejaculating despite sufficient sexual arousal and stimulation. This can be quite concerning, especially when it happens for the first time.

How Does Male Ejaculation Function?

Many things facilitate an ejaculating penis, so it's common to wonder how do you cum? A basic answer is emission and expulsion, which involves many different components in the reproductive system that all work together. The following are the elements involved and the role they play.

  • Testes: Sperm are produced in the seminiferous tubules within the testes.
  • Prostate: The prostate gland produces a thick, white fluid that helps to nourish and protect sperm. The fluid from the prostate makes up about 20% to 30% of the semen.
  • Seminal vesicles: Located behind the prostate, they produce a fluid that helps sperm swim and transports nutrients to the sperm. Fluid from the seminal vesicles makes up around 50% to 65% of the semen.
  • Vas deferens: The vas deferens is a long, coiled tube that transports sperm from the epididymis to the penis.
  • Urethra: The urethra is the tube that carries urine and semen through the penis and to the outside of the body.
  • Cowper's glands: Produces pre-ejaculate that neutralizes the acid in the urethra before ejaculation.


The first thing that happens in male ejaculation is the emission phase which occurs in a fraction of time. It's triggered by your body's autonomic nervous system via nerve signals sent from the reproductive system to the spinal cord. The prostate closes the urethra to prevent urination, and the bladder neck closes to prevent the semen from travelling backwards.

Next, the fluid from the seminal vesicles and prostate coats the urethra providing safe travel for the sperm. Sperm is released from the testes and travels up the urethra, combining with the seminal fluid.

Once these processes have happened, it will be impossible for the expulsion phase to stop.


During this phase, the semen exit the body through the penis. This happens by the muscles in the penis and pelvis contracting multiple times, which causes the semen to move up the urethra at speed.

Expulsion typically occurs in tandem with the male orgasm, the final stage of sexual arousal. It exits the penis at speed but slows down as the volume of semen decreases. Once ejaculation is over, there will be a refractory period where the man will be unable to achieve another erection.

What Is Precum?

Before male cumming the body will produce pre-ejaculate (precum). Precum is a clear, sticky fluid produced by the Cowper's glands. These glands are located just below the prostate. Precum is released during sexual arousal and can contain small amounts of sperm.

It's noticeable as a slight build-up of fluid on the tip of the penis. Precum's function is to lubricate the urethra so the semen can safely leave the body. Small amounts of sperm can make their way into pre-ejaculate as the prostate gland contains low levels of sperm. If there has been a recent ejaculation, there may be trace amounts of sperm in the urethra as well.

Although it's not as common, it is possible for precum to cause pregnancy. This occurs when the precum comes into contact with the vagina, and there is sperm in the fluid. If you're worried about becoming pregnant from precum, you can use a condom or another form of birth control to help reduce your risk.

What Is Nocturnal Emission?

Nocturnal emissions are more commonly known as "wet dreams." They are spontaneous orgasms that occur during sleep without any sexual stimulation. Wet dreams are perfectly normal, and most males will experience them at some point in their lives. While wet dreams are typically associated with puberty, they can occur at any age.

Benefits of Regular Ejaculation

Regular ejaculation is a good indicator of your health. It can help to relieve stress and improve your mood. It also helps to keep your blood pressure low and your heart healthy.

Male cumming requires the coordination of many different body systems, including the nervous and reproductive systems. It is an indication that everything is working as it should be and that the man can reproduce successfully.

Ejaculation can also decrease a man's risk of prostate cancer. A study conducted in 2016 found that males who ejaculated more than 20 times a month had a 20% reduced risk. It's believed that regular ejaculation helps to keep cancer-causing substances from the prostate.

Ejaculation Issues

Ejaculation issues are a common problem that many men face. It can cause embarrassment and frustration and can hurt your relationship. Despite being perfectly natural in most instances, there is sometimes cause for concern if you have long-term issues with ejaculation.

Premature ejaculation

Premature ejaculation is when a male cums too quickly during intercourse. It affects roughly one-third of all men, at least one in their lifetime. It's caused by psychological and biological issues. Problems are often temporary, but they can be treated using medical and behavioural therapies if they persist.

Delayed or absent ejaculation

If ejaculation takes longer than usual or is entirely absent, this could result from psychological issues such as depression and anxiety. It can also be caused by medication or alcohol use.

Blood in semen

Blood in the semen is not always something to be overly concerned about. It's known as hematospermia and usually resolves without medical intervention. For men younger than 40, there shouldn't be any serious problems causing the blood.

Men over 40 should consult a doctor if blood frequently appears in their ejaculate. This could indicate problems with their reproductive organs, such as prostate cancer, inflammation, or trauma.
