Semen: Things to Know About Swallowing Semen

What exactly is semen?

Semen is a “viscous, creamy, slightly yellowish or grayish” substance made up of spermatozoa — commonly known as sperm — and a fluid called seminal plasma. In other words, it contains two separate components: the sperm and the fluid.

Semen, also known as seminal fluid, is an organic fluid created to contain spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize the female ovum. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or “swim”. Semen is produced and originates from the seminal vesicle, which is located in the pelvis. The process that results in the discharge of semen is called ejaculation.

Sperm — about 1 to 5 percent of the semen — are the tadpole-like reproductive cells that contain half of the genetic information to create human offspring. The seminal plasma fluid, which is about 80 percent water, makes up the rest.

Is it actually safe to ingest Swallowing?

This is frequent asked question, especially when you have mistakenly swallowed your partner’s semen. For the most part, yes, the components that make up semen are safe to ingest.

NOTE: Swallowed semen is digested in the same way as food.

However, in very rare circumstances, some people might discover that they’re allergic to semen. This is also known as human seminal plasma hypersensitivity (HSP).

Though rare, this sensitivity is something to be aware of in case you find yourself experiencing an allergic reaction.

Is semen proteinous in nature?

Despite its reputation for being a rich source of protein, you would likely have to consume gallons of semen to see any dietary health benefits.

Although the amount of ejaculate varies from person to person — depending on a variety of factors, such as age and health — protein is only a small part. It’s about one-twentieth of the entire fluid.

Other content of  semen?

Along with the sperm, protein, and water mentioned above, it also contains a variety of other components, including:

  • sugar, both fructose and glucose
  • sodium
  • citrate
  • zinc
  • chloride
  • calcium
  • lactic acid
  • magnesium
  • potassium
  • urea

If it has actual nutrients, does that mean it has calories?

>>Also read this: Is Watery Semen normal or Not?

Yes, but not as many as you might think. Contrary to popular belief, sperm isn’t highly caloric.

Each teaspoon of ejaculate — the average amount of ejaculate produced at one time — is around five to seven calories, which is about the same as a stick of gum.

What does semen taste like?

There’s no single description of what semen tastes like because it can vary from person to person.

Note: To some, it can taste 
bitter and salty, while for others,
it can taste sugary sweet.

Although there isn’t a direct link proving that a person’s diet directly affects the taste of their sperm, there’s some anecdotal evidence.

There are a few foods that could make semen taste more palatable, or less acidic, such as:

  • celery
  • parsley
  • wheat grass
  • cinnamon
  • nutmeg
  • pineapple
  • papaya
  • oranges

On the other hand, many believe that a more intolerant bitterness could be attributed to other foods, as well as drug-like substances, such as:

  • garlic
  • onions
  • broccoli
  • cabbage
  • leafy greens
  • asparagus
  • meat and dairy products
  • alcohol
  • cigarettes
  • coffee

What does Semen smell like?

Similar to taste, the smell of semen can vary quite a lot depending on circumstances like diet, health, and hygiene.

In many situations, it can smell like bleach or other household cleaners. This has to do with its makeup of ingredients, in order to provide a pH level where the sperm can thrive.

Unlike the vagina, which naturally skews more acidic, semen tends to be neutral or slightly alkaline.

It stays around 7.26 to 8.40 on the pH scale — which ranges from 0, highly acidic, to 14, highly alkaline. On the other hand, if semen smells musky or fishy, this could be due to outside factors.

Like taste, a more putrid smell could be attributed to diet, in the same way that asparagus affects the scent of urine. Sweat and dried pee can also make it smell bitter.

Is semen really a mood booster?

Potentially! There’s some research that shows there could be natural antidepressant properties in semen.

These may include:

  • endorphins
  • estrone
  • prolactin
  • oxytocin
  • thyrotropin-releasing hormone
  • serotonin

A 2002 study conducted by the State University of New York at Albany surveyed 293 college-age females to see if exposure to semen, without the use of outside condoms worn on the penis, affected their overall mood.

According to the survey, those who were directly exposed to semen showed significantly better mood and fewer symptoms of depression.

However, this study should be taken with a grain of salt. Although the above study’s findings leaned in favor of semen as an antidepressant, the National Health Service of the United Kingdom points out that engaging in sexual activity in general is linked to a decrease in depression. As with any claims, more research is needed to validate the findings.

What about stress relief?

In the same vein as the studies that show evidence for the natural antidepressant properties of semen, some believe it could also have stress-relieving properties.

This claim is due to the mood-boosting properties of oxytocin and progesterone hormones, the both of which are found in semen.

It’s also thought that vitamin C and other antioxidants found in semen may help reduce sperm impairment by fighting oxidative stress within semen.

Are there any other health benefits ?

Maybe. Similarly to how some studies have shown mood-lifting and anxiety-reducing benefits, semen exposure could help with pregnancy health.

A 2003 case-controlled study found that females who were exposed to sperm for longer periods, both before and during pregnancy, were less likely to develop preeclampsia, a rare pregnancy complication. However, this is only one study, and more research is needed to support these findings.

Why do some people get tired afterward?

Semen contains melatonin, the natural hormone your body releases to regulate sleep cycles.

This may explain why some people feel tired after swallowing it or being exposed to it during intercourse.

There hasn’t been any research on this, so there’s no way to know for sure.

The Volume and Consistency of Semen

The average volume of sperm produced at ejaculation is two to five milliliters. Generally, the volume of ejaculate will increase with the time since last ejaculation (up to some maximum) and with proper hydration.

If it was recently ejaculated, you may expect semen to be a body-temperature, coagulated fluid, with the viscosity of a heavier grade, room-temperature motor oil and with the density of milk.

Can swallowing put you at risk for an STI?

Just like any other form of unprotected sex, swallowing semen can put you at risk for an STI.

Without a barrier birth control method, bacterial infections, like gonorrhea and chlamydia, can affect the throat. Skin-to-skin viral infections, like herpes, can result from contact.

Before you and your partner engage in any unprotected sex, including oral stimulation, make sure to have a conversation about when you were last tested or if you think you should get tested.

Health Benefits of Men’s Semen

Semen Elevates a woman’s Mood

According to a study which analyzed the effects of semen’s “mood altering chemicals”, oral sex makes women feel happier.

Scientists at the University Of New York conducted a study which compared the sex lives of 239 females to their mental health. It was discovered that seminal fluid contained chemicals that elevates a woman’s mood. Strange but true.

Survey results showed that women who were directly exposed to the semen showed significantly better mood behavior and lower symptoms of depression.

Being in a good mood will help you be more positive and productive, it will also reduce stress levels caused by worry.

Give it a try next time you and your man have oral sex, and you’d be “happy” you did!

Semen Helps Women Fight Insomnia

Usually, after a good round of sex, it is very common for both man and woman to fall asleep. You may think it’s all the “hard work” that put you to sleep, but it’s not.

Studies have shown that whether you swallow sperm or it enters your blood stream through your vagina, it will help you fall asleep fast, thanks to the chemical melatonin which is found in semen.

This component of a man’s semen is a form of relaxant that helps women be at ease and fall asleep.

So, if you’re a lady who keeps struggling with sleep, then I suggest you swallow your man’s semen (as long as he is virus free). Thank me later!

It Adds Extra Nutrients To Your Meals

According to the research of Paul Fotie Photenhauer, it adds a world of nutrients to your meals.

As I mentioned earlier, semen is rich in minerals and vitamins, and it has been proven that it adds some “extra value” to your meals. Besides the extra nutrients, it has a great texture so it blends well with food. Next time you want to make dinner, consider adding some semen to it. It goes very well!

Semen Is An Anti-depressant

The chemical components of semen helps fight depression. This may seem strange (or new) to you but it’s true!

Scientific studies have proven that women who swallow their man’s sperm have lower chances of being depressed. This is not to say that it is the sole answer to depression, it is just a statement of fact that it’s components have anti-depressant qualities.

The nerve growth factor found in semen is a vital hormone that’s missing in the brains of those who have been diagnosed with major depressive disorders. This naturally means that increasing nerve growth factor would make women happier.

I heard some people are allergic — is this true?

Yes, but it’s extremely rare.

Although there isn’t a lot of hard data, semen allergies may affect up to 40,000 females in the United States.

That’s a small percentage of the nearly 160,000,000 females living in the U.S.

Symptoms of a semen allergy usually show up 20 to 30 minutes after contact or ingestion and may include:

  • pain
  • itching
  • redness
  • swelling
  • hives
  • difficulty breathing


Seek immediate medical attention if you have trouble breathing or experience other signs of a severe allergic reaction.

Symptoms of allergy will likely vary from one person to the next, as will the duration of symptoms. See a doctor or other healthcare provider if your symptoms persist or worsen.

So is it better to spit or swallow semen?

Whether you choose to spit or swallow is entirely up to you and your personal preferences.

Before making a decision, make sure that you have an open conversation with your partner about their STI status. This will help you evaluate the overall level of risk.
