Have to admit it’s a good question
Classic nature versus nurture debate. Assuming identical male twins, anyway. Anything else and the answer is far more likely to be “no”. Bob probably has a bigger D than his twin sister Sally. Probably.
But once you narrow it down, well, they really ought to be the same unless something significant happened to one and not the other. Note that the significance of that thing might not at first appear to be significant, however.
e.g. Maybe one time and only one time, Mom or Dad fed one of them twice by accident when the twins were infants and then had to the feed the hungry one “again” when he wouldn’t stop crying (if they realised the error or not).
That one extra bottle of milk with no other differences might have made for a lifetime of difference between the two. And you still can’t be sure which one would end up better endowed. Maybe something latent in the twins’ genes would gives a hungry baby the advantage later in life, so to speak.
ETA: If this sort of thing is your cup of tea, you might find pictures out there on the internet. If it isn’t, you might want to perform the same experiment using women’s attributes instead. I understand certain forms of twin “art” are quite popular.
She’s mad because she doesn’t know the answer
Welp…I went down an NSFW image search rabbit hole and, although far from being conclusive, my opinion is that yes, the penises are pretty much the same on identical siblings (saw a few triplets).
Beggs the follow up question do identical female twins have the same breast size if they are approximately the same body weight
From being a female twin
Yeah, close enough. Personally I’m like 6 inches taller and weigh more because birth trauma, but we are identical. Twin is shorter in general, but just imagine shrunk a bit but proportionate. However you spell that.
Points to smaller twin I want a girl like her, but Supersized.
“Funny you should say that…”
They do a shared Tinder and then when someone swipes to accept, then they prompt for “would you like to supersize”, so they know which sister gets the match.
Unfortunately for them, I am married and have been for awhile now. And my twin is asexual!
At least it wouldn’t be the guys who want both of us together, always hated that.
Twins are identical, and mirror twins are identical in every way except their features are swapped.
What about evil twins?
Ah, mirror universe twins? One dresses more provocatively.
And tend to be a bit campy

Can you provide these images … for science?
I can actually answer this one. I’m a fraternal twin. I can confidently say that my dick is bigger than my twin brother’s. As for how I know that… As kids we had no issues bathing together… And later in life we just never cared about either being nude. Nothing sexual just a straight up lack of feelings one way or the other.
Also I lived with him and his gf for a bit and she accidentally walked in on me as I was getting out of the shower and her exact words were “I hooked up with the wrong twin”… Unfortunately for her I’m gay.
Some twins have different size of boobs so not necessarily?
Aren’t breasts mostly fat so they’re more affected by nutrition?
Not really. There are plenty of skinny girls with large breasts.
Well I didn’t mean to say that nutrition is the only factor, just one of them
Mind if I borrow that line?
I mean, most individuals have different size boobs.
Most boobs are different sized, even when they’re attached to the same singular person
Well, I thought that’s what I was saying.
Sorry, my reading comprehension is terrible when boobs are involved

Single vs multiple eggs twins, I assume?
Sometimes. Once out of the hatch, environmental factors change each individual potentially in a different way. So while the template might be the same at start, further mutations can branch out in other aspects.
I have a science question. What factors contribute to growing a bigger dick?🤔
Estrogen/testosterone balance probably. There are certain dietary factors that can change this. Tofu for instance has a chemical pretty analogous to estrogen, hence the term “soy boy”
Plant estrogens, especially in the instance of soy, have been overwhelmingly shown to have no effects on our endocrine system. If growing breasts were as easy as eating tofu, a lot of transfem people would’ve been doing that over prescription meds
That logic makes a lot of sense. I only read this one scientific article which took a compilation of other findings, but it seems the short answer is: we don’t know yet and more research is needed, but if there are effects they are likely quite minimal.
If this was true then every Asian man and woman would have tig ol biddies which is obviously untrue.
maybe one had undersized tighty whiteys and the other had boxers.
More testosterone during the growth phase. So in theory, if one is leading a life that produces more or less testosterone, then they could be different.
Good question. For serious answers, try asking here https://lemmy.world/c/askscience or other similar communities.
On my part, I can vaguely extract some theories from memory.
One suggests some kind of insufficiency or excess during the growth phase can result in abnormal size of one or more organs, whether larger or smaller and usually accompanied by circulatory problems.
Another suggests it a remnant of evolution, whether specific to a type of environment or early societal development.
Of course, there’s also the chemical imbalance issue caused by unchecked industrial exploitation and pollution that causes the entire biological chain to mutate uncontrollably.
But at their base, it’s usually hormones that are directed in some way by something either to grow or to stunt.
You gotta get the right kit. Ever grown crystals?
Where’s the hidden mouse in this one? I just can’t find it.
it’s very well hidden
The quality that my app is loading this image is terrible - is that it within the hair on the woman’s shoulder?
yeah he’s very shy but he’s there
Up the interviewee’s butt. It brings him confidence.
Hermione is mad at him. Maybe since she’s with Ron, she suppresses all her naughty thoughts about Fred and George.
Malfoy suppresses his rage. He knows for sure that Fred had a bigger dick, but has to settle with George’s piece.
Which begs the follow up question: are all Slytherins bottoms?
Follow up, follow up: Was Voldemort a bottom?
This thought is supported by the little known fact: his nickname was He Who Must Not Be Bottomed
Do twins look the same naked? Do siblings? Do sisters have the same boobs? Do brothers have the same balls?
This is incredible!
Beautiful, just beautiful. This! This is why we’re spending all that effort unwrapping those scrolls that Vesuvius tried to bury for some reason all those millennia ago.
brothers have one identical ball and one unique ball.
I don’t have any actual brothers but I do have friends who might as well be brothers. Are my balls both unique or is one of them identical to that of my bros?
Plato says we all have imperfect copies of the ideal testicles, but Aristotle says you shouldn’t rely on theorising but test scientifically. Only by a thorough mutual examination of all your friends’ testicles can you really know.
yeah when men spend a lot of time with one another their testes synchronize
Thanks to the power of the internet…you can definitely answer this for yourself.
