It is often considered a taboo subject.
But scientists are finally lifting the lid on the male penis and what it might look like in the future.
For men concerned about their member size, researchers have recently revealed that the male penis is getting longer.
In fact, based on current growth rates, the average penis length could exceed 8.5 inches before the end of the century.
But this may not be the only change that awaits humanity.
An entire global community of science fiction-inspired ‘biohackers’ is already making adjustments to the body using technology such as implants.
And experts predict that the biohacked penis of the future, dubbed ‘penis 2.0’, will have some major changes in store.
From dildo-style vibrations to greater sensitivity and even better sperm, here’s what it could look like.

IMPROVED SEMEN
According to Simon Underdown, professor of biological anthropology at Oxford Brookes University, any substantial changes in penis size and shape over the next few thousand years will likely be due to self-made alterations.
Already in the 21st century there is an entire global community of science fiction-inspired ‘biohackers’ who have implanted DIY cybernetic devices.
In the future, medical improvements could improve the way sperm move (“motility”) or even their shape to improve their ability to penetrate the cell membrane of the egg.
“If there is enough demand, driven by fashion or social trends, to modify body parts, then we are probably not too far away from being able to do it genetically,” Professor Underdown told MailOnline.
“That’s what makes humans really interesting: we’re close to the point where we can alter biological processes because we want to, rather than there being strong biological selective pressure.”
Biologists could also take inspiration from the plant kingdom, specifically the exploding cucumber, to figure out how to make ejaculate travel faster and further.
This peculiar plant expels its seeds at an incredible speed of 70 kilometers per hour, much faster than human ejaculation (around 45 kilometers per hour).

Mark Maslin, professor of paleoclimatology at University College London, says the human penis is “extremely boring” in relative terms. This image shows penises of more complex primates: brown lemur (a), white-bellied spider monkey (b), black-capped squirrel monkey (c), macaque (d, e, f), baboon (g) and chimpanzee (h ).
GREATER LENGTH
The human penis could lengthen sooner than we expect, placing the average size well above that of our closest living relatives.
According to a 2023 Stanford University study, men’s penises have grown on average at an “alarming rate” in just 30 years.
Referring to data from 55,761 men, the researchers found that the average erect penis increased 25 percent in length between 1992 and 2021, from 4.8 to 6 inches.
At this rate, the average length could surpass 8.5 inches before the end of the century.
“If we’re seeing such rapid change, it means something powerful is happening in our bodies,” said lead author Dr. Michael Eisenberg.
According to the authors, environmental rather than evolutionary factors, such as pollutants or inactive lifestyles, may in some way be causing this increase.
And if you think this is good news for women and a confidence boost for men, scientists worry that it’s actually a bad thing.

Researchers found that penis length has increased in men over the past 30 years, from 4.8 inches in 1992 to 6 inches in 2021. While that may seem positive, they fear it is linked to rising levels of infertility.
Kris Kovarovic, a researcher in the department of anthropology at Durham University, said larger penises could, in fact, prevent reproduction without changes in the size of the female vagina.
“That would definitely have a negative impact on reproductive success, and smaller penises would probably be selected for,” he told MailOnline.
VIBRATIONS ON DEMAND
Similar to vibrating love eggs, tiny biohacking implants could make the penis vibrate on demand.
Rich Lee, a Utah salesman who describes himself as the “Elon Musk of sex tech,” is an intrepid biohacker exploring this avenue.
Lee, CEO of a company called Cyborgasmics, is working on a device called ‘Lovetron9000’, which has already been demonstrated as a prototype.
Lovetron9000 can be implanted under a man’s pubic bone to make his penis vibrate, providing a more pleasurable experience for the couple during sexual intercourse.
According to the Cyborgasmics website, the Lovetron9000 vibrating pelvic implant is still “coming soon,” although it was first promised more than five years ago.

INTEGRATED CONTRACEPTIVE
Another improvement could be a built-in birth control system that could be turned on and off depending on whether you are trying to have a baby.
Canadian bioethicist George Dvorsky speculates that future improvements could involve a “switch” that blocks the passage of sperm into the seminal fluid.
This could be done by injecting nanobots (small programmable devices the size of a red blood cell, invisible to the naked eye) into the vas deferens, the channel where semen and sperm combine.
“Or, nanobots could be on the hunt for specific sperm proteins and take evasive action,” Dvorsky wrote for Gizmodo.
Dvorsky also hopes that we can increase pleasure by activating areas of the brain that receive sensory information from the penis.
There could even be internet-connected, Bluetooth-enabled penises that allow people to engage in virtual sex or transmit biometric statistics to an app.
Realistically, biohacking may be the only way for the human penis to change substantially over the next tens of thousands of years, assuming we still exist as a species.

The human penis has not evolved in the tens of thousands of years since the time of the Neanderthals, the extinct archaic human species.
According to experts, the human penis has likely lengthened since our distant ancestors began walking on two legs (about five million years ago).
However, it hasn’t really changed in the last few thousand years since the time of the Neanderthals, our closest ancient human relatives.
Scientists consider the human penis “opaque” because it does not have bumps, ridges, kinks or any other unusual features that other primates such as chimpanzees and lemurs have.
Dr Emily Willingham, author of ‘Phallacy: Life Lessons from the Animal Penis’, said humans have ‘pretty simple penises’ in the animal kingdom.
Thousands of years of human evolution have favored larger brains rather than substantial changes to the human phallus.
“We followed evolutionary, genetic and behavioral paths separate from our closest living relatives at least 6 million years ago,” Dr Willingham told MailOnline.
“We are alone and we are our own solitary species, but what is clear is that in shaping us, nature favored our brains over… well, many other things.”
