An “interesting” TikTok video broke down exactly what happens when someone performs oral sex on someone with a penis and swallows their semen.
Video in question – shared to TikTok doctor boogie – Reveals what happens when “semen enters” the body. Specifically, when semen enters the body through the mouth.
A model with a skinless body is seen dripping what appears to be a pint of milk, but is actually meant to represent semen.
The video then shows semen running down the person’s throat, with the white liquid studded with tiny shapes representing sperm.
health line Sperm make up “about 1 to 5 percent of semen,” with “seminal fluid, which is mostly water,” “making up the rest.”

“When semen is swallowed, it passes through the esophagus just like any other swallowed liquid and quickly reaches the stomach,” a voiceover says in the video.
Strong acids in the stomach, such as pepsin, “rapidly break down proteins and inactivate sperm cells.” I mean, what about that rumor I heard in high school that fellatio can get you pregnant? You can lay it down firmly.
But how long does semen stay in the body?
Well, given that it has “minimal fiber or amount,” it “moves through the stomach relatively quickly and can be emptied quickly but without incident.”
The “processed mixture” then enters the small intestine, where digestion continues with additional enzymes that agitate the mixture and “small amounts of nutrients are absorbed.”
It is important to emphasize “small” here, meaning a mouthful containing an insignificant amount of sperm.
In minimal amounts, it “may be absorbed into the bloodstream,” but “there is no significant nutritional benefit or change.”
Healthline further concurs: “You would likely need to ingest several gallons of semen to see any health benefits from the diet.”
Therefore, don’t replace your protein shake right away.

Semen does not take up much space in the stomach. Without us noticing, it is quickly digested and completely eliminated from the body, “broken down and excreted as waste.”
Healthline added that while semen is “safe” to ingest “in most cases,” some people may prove allergic in “very rare circumstances.”
There is also a risk of contracting sexually transmitted diseases, so talk to your sexual partner and only do what makes you feel comfortable.
