Scientists have predicted what penises could look like in the future and it sounds like something straight out of a sci-fi movie.
The topic of one's manhood is a sensitive one, with studies on the matter certainly shady as you can easily lie about the size of your, erm, downstairs.
Science buffs have even gone as far as to declare that something 'powerful is happening to our bodies' after releasing their findings.

Recent research has indicated the penis size is in fact growing to the point where the average could reach 8.5 inches before the end of the century.
But that's not all - and this is where things take a bit of strange turn.
Experts reckon the likes of built-in contraception and automated implants could also be on the agenda. See, told you it was like a movie.

Simon Underdown, professor of biological anthropology at Oxford Brookes University, told the Daily Mail: "If there is enough demand, driven by fashion or societal trends, for tweaking bits of the body then we’re probably not that far away from being able to genetically do that.
"That’s what makes humans really interesting — we’re close to the point at which we can mess about with biological processes because we want to rather than there being a strong biological selective pressure."
Researchers found the average erect penis size has jumped 25 percent in length from 1992 up until 2021.
Back in the early 1990s, the average erect penis size was 4.8 inches.

Dr Michael Eisenberg, who is the lead author on the latest study, said: "If we're seeing this fast of a change, it means that something powerful is happening to our bodies."
While this study is all about the male reproductive system, experts have said an increase in penis size could see changes to the vagina too.
Kris Kovarovic, a researcher at Durham University's department of anthropology, told the Daily Mail: "That would definitely have a negative impact on reproductive success – and smaller penises would likely be selected for."

Dr Emily Willingham, who worked on 'Phallacy: Life Lessons from the Animal Penis' as its main author, has also been speaking about the intriguing findings.
"We went our separate evolutionary, genetic and behavioral ways from our closest living relatives at least six million years ago.
"We are on our own and are our own lonely species, but what's clear is that in shaping us, nature favored our brains over ... well, a lot of other things."
