Swole From Sperm? Here’s How Much Protein is Actually in Sperm

Can swallowing sperm get you swole?! If you’re on a fitness journey and checking out the nutritional facts of semen, well, first off you sound fascinating. Second, you're probably wondering, “Does sperm have protein?”

The short answer is “yes," but that is just the tip of the nut nutrient iceberg. These little swimmers are loaded with micronutrients. But should you bother adding a shot or two to your post-workout shake? Let’s take a look at the nutritional makeup of jizz, why folks are asking about it, and whether or not it will give you the eye of the tiger.

The Nutritional Content of Semen

While a load contains plenty of nutrients, don’t get too excited. Let’s start with the king of macros: Protein. 

Studies have shown that in 100ml of semen, a bit above 3fl oz, you get about 5g worth of protein. Considering that the average cumshot is about 5ml, you’re only getting around .25g every time you swallow. So, unless you know someone who normally fires off enough baby gravy that the TSA would confiscate their balls, you're not getting a lot of muscle building potential out of swallowing semen. 

So, how much protein does sperm have compared to other sources of protein? Again, not much. Even if we stick to 100ml, or convert it to 103g (thanks, Google), it doesn’t stack up that well to much easier to acquire protein sources. 

100ml of whole milk would give you about 3.5g of protein, less than sperm but much easier to find. 103g of beef would give you 27g, with chicken offering 28g. Which would you rather have? A burger or a travel-sized bottle of cum?

Sperm does contain an insane amount of nutrients — zinc, iron, B vitamins, and many other beneficial ingredients — for its volume but not enough to have any real effect on you. Swallowing semen for health benefits is like expecting to get wasted off of a sip of light beer. 

Is swallowing sperm bad for you?

Swallowing semen is perfectly safe as long as the semen in question is safe. 

Getting back to basic sex safety, ingesting bodily fluids can always carry a risk of STIs. So, make sure you and your partner are tested regularly and keep an open line of communication when it comes to sexual health, as well as health in general.

There could be benefits of swallowing sperm, but not from any secret component or special nutrients in jizz. If you enjoy swallowing semen or it's part of your spiritual practice (i.e. witchcraft and sex magick), then go for it and enjoy!

Anything safe and consensual that makes you feel good and relieves stress is beneficial for your mental health, and consequently, your physical health. 

Other Frequently Asked Questions about Sperm

Here are a few more common questions about the nutritional content of sperm:

Does sperm have calories?

Yes, but a very small amount. About 5-25 calories per shot. So, swallowing definitely won't ruin your diet.

Does sperm have Vitamin D?

Again, yes, but not enough to make a difference. Stick to sunlight, supplements, or Vitamin D rich foods like like eggs or mushrooms.

What is the difference between sperm and semen? 

Sperm are the actual reproductive cells you see swimming around under a microscope — or the opening of Look Who’s Talking.

Semen is the fluid they swim through. It has its own nutrients, like amino acids, but semen is more of a transportation vessel for sperm. 

The Bottom Line

So, does sperm have protein? Yes, but there's so little in each cumshot that the juice ain’t worth the squeeze, literally. Stick to a diverse and balanced diet full of animal and plant-based proteins. 

Always practice safe oral sex and be sure the semen you swallow is safe. Even if there are no real nutritional benefits to swallowing semen, there’s no real harm either. If you enjoy a shot of spooge and it makes you feel good, the bottom’s up!
