Mind-blowing simulation shows exactly what happens when semen enters your body

An 'interesting' TikTok video has broken down exactly what happens if someone gives oral sex to someone with a penis and swallows the semen.

The video in question - shared to TikTok by Dr Boogie - reveals what goes on inside your body when 'semen enters' it. Specifically, when semen enters your body via your mouth.

A model of a body without skin can be seen downing what looks like a pint of milk, but is, in fact, meant to represent semen.

The video then shows the semen rushing down the person's throat, the white liquid littered with little shapes representing sperm.

Healthline explains that sperm makes up 'about one-to-five-percent of semen' and its 'seminal plasma fluid, which is mostly water' that 'makes up the rest'.

"When semen is swallowed, it travels down the oesophagus just like any other swallowed fluid, reaching the stomach quickly," the video narrates.

Strong acids in the stomach, like pepsin, 'quickly break down the proteins and deactivate the sperm cells' - so those rumors you heard in high school about getting pregnant from fellatio? You can put them firmly to bed.

But how long does semen stay in your body?

Well, given the 'minimal fiber or bulk,' it 'moves relatively quickly though the stomach, leading to rapid but uneventful gastric emptying'.

The 'processed mixture' then enters the small intestine where digestion continues via additional enzymes shaking up the mix, 'absorbing any small amount of nutrients'.

It's important to emphasize the 'small' here - a mouthful of sperm containing non-significant amounts.

The minimal amount it does have 'may be absorbed into the bloodstream', but offers 'no significant nutritional benefit or change'.

Healthline further echoes that 'you would likely have to consume gallons of semen to see any dietary health benefit'.

So don't start swapping out your protein shakes anytime soon.

Neither does the semen take up much room in your stomach. Before you know it, it's digested quickly and fully out of your body, 'broken down and eliminated as waste'.

Healthline adds 'for the most part' semen is 'safe' to ingest, but in 'very rare circumstances' some may discover they're allergic.

It can also put you at risk of contracting an STI, so make sure to have conversations with your sexual partner and only do what you're comfortable with.
