Pre-cum is the clear fluid that moistens the tip of the penis while a man is sexually excited.
What is pre cum?

Pre-ejaculatory fluid, better known as "pre-cum," is the opening act of the sensational male orgasm.

Though small in quantity, pre-cum plays a big part in men's sexual experience.

Follow along as we explore men's pre-cum and why it happens to the most common mis-cum-ceptions surrounding this fluid!

What Is Pre-Cum?

Pre-cum, short for pre-ejaculatory fluid, is a clear and colorless slippery liquid that men produce before they orgasm.

The bulbourethral glands (also known as Cowper's glands), a pair of pea-sized glands nestled near the base of the penis just beneath the prostate gland, produce this mucus-like fluid.

Unlike semen, pre-ejaculation fluid does not consist of sperm cells. However, pre-cum may have residual sperm mixed in as it is expelled through the penis during ejaculation (more on this in a moment).

How Much Pre-Ejaculate Fluid Is Normal?

Healthy males generally produce up to 4 mL of pre-ejaculatory fluid during times of sexual arousal. Though it's only a few drops, pre-cum plays a crucial role in sexual health for several reasons!

The Purpose of Pre-Cum

You might wonder, “Why do we need one fluid before releasing another?”

Pre-cum is like the starting act of a show, helping to warm up the crowd before the main performance arrives.

It serves some significant roles:

It Lubricates the Penis

Thanks to its sticky composition, pre-cum acts as a natural lubricant during sexual intercourse. This lubrication helps reduce friction with penetration, making sex a lot smoother and more pleasurable for everyone involved.

It Cleans the Urethra

As the first fluid exits the urethra, pre-ejaculate fluid clears any residual urine or foreign particles from the tube. That ensures that semen can ejaculate through the urethra without being stopped or mixed in with any harmful bacteria.

It Protects the Semen

Since both ejaculate and urine use the same path to leave the body, there is a chance that sperm may be affected by the acidic environment. Pre-cum helps neutralize acidic urine, making semen more potent during discharge.

When Pre-Cum Happens

Similar to regular ejaculation, pre-cum only appears when a man is sexually aroused.

As a natural response to excitement and pleasure, pre-cum can be triggered before sexual activity begins, such as during foreplay. That can happen well before your pants come off!

Common Pre-Cum Misconceptions

Pre-cum is a highly debated topic, so let's get honest about pre-cum and clear up the confusion by addressing these three common mis-cum-ceptions.

Misconception #1: Pre-cum contains sperm

People commonly assume that pre-cum contains a high concentration of sperm. Instead, this lubricating pre-ejaculatory fluid is a mixture of mucus and enzymes, making up only <1% of semen.

That said, a small chance exists that pre-cum may mix with sperm cells already in the urethra, leading to their early ejaculation alongside pre-cum (before orgasm occurs).

Misconception #2: Pre-cum won’t make you pregnant

The chances of becoming pregnant from pre-cum are low– roughly 4%. Said that this value relies on executing the pull-out method flawlessly.

For the very reason we described above, there may still be some sperm cells present in pre-cum. While this is rare, it means that pre-cum entering your partner's vagina can potentially lead to unintended pregnancy.

Using a reliable form of contraception not only helps in preventing pregnancy but it will also minimize the risk of spreading sexually transmitted infections (STIs).

Misconception #3: Pre-cum is a form of premature ejaculation

That is also false. While pre-cum is an indicator of sexual arousal, it does not necessarily mean that you will be ejaculating anytime soon.

Many men pre-cum quite early, some even up to 30 minutes before they are ready to finish.

On the other hand, premature ejaculation has everything to do with the actual ejaculatory response associated with an orgasm.

Safety and Health Concerns

Although pre-cum itself is not associated with any significant health concerns, as a bodily fluid, there are specific health and safety considerations to keep in mind.

It’s essential to understand the risks involved in exposing your pre-cum to another person during any sexual encounter.

As mentioned earlier, there are rare occasions where pre-cum coming in sexual contact with a female partner can lead to pregnancy. It is a common occurrence in couples relying solely on the withdrawal method (pulling out) as a form of contraception.

According to National Health Service, millions of sperm can still be found in the pre-ejaculate fluid as soon as the penis becomes erect.

Additionally, there is a risk of exposing someone to STIs while engaging in unprotected sex, as pre-cum may carry infectious materials.

Using a reliable form of contraception is the best method to both prevent pregnancy and the spread of infection. Things like hormonal birth control pills and intrauterine devices (IUD) are great for minimizing the risk of pregnancy. At the same time, condoms are ideal for protecting against STIs.

What is pre-cum?

Pre-cum, also known as pre-ejaculate, is a clear, colorless, and viscous fluid made from the bulbourethral glands and excreted through the urethra.

When does pre-cum happen?

As the name describes, pre-cum shows up before you cum! Pre-cum appears during times of sexual arousal to help lubricate the tip of the penis in preparation for ejaculation.

Is there sperm in pre-cum?

While pre-cum does not contain sperm, it is possible for live sperm to linger inside the urethra to be then mixed into pre-cum while it's on its way out of the penis.

Does pre-cum cause pregnancy?

Yes, it's certainly possible to get pregnant from pre-ejaculate even if the man pulls out before climaxing.
