Is penis size hereditary?

Nonsense!

At one time, in physical education in schools and in YMCAs, males swam nude. We also showered together nude and changed clothes in open locker rooms. If you don't believe it, do some google searches, like "YMCA nude swimming" and "school nude swimming".

Many kids are unnecessarily concerned that their endowment is inadequate. They've seen porn stars on the Internet and don't realize that those stars have a penis which is way above average in size. If we still had nude swimming in schools and YMCAs they would know that there is considerable variation in penis size and that they are not deficient.

Males swam nude at school and the Y? Bullshit. When was this? I’m in my 40s and it hasn’t been in my life time. Also, when they were swimming were they rocking boners? Get outta here.

At the YMCA I swam at in the late 1950's clothing was left in a locker we all hit the showers on the way into the pool. The YMCA did not want dirty sweaty bodies in their pool water and we washed the chlorine off our body on the way back to the locker room to dress. The only erections I ever saw was on those that probably soaped their penis somewhat vigorously. There could have been other erections but they were never brought to my attention by any others males swimming. The two lifeguards at the pool were nude as well. I have no idea about swimming at any school as not school I went had swimming to participate by students or a pool.

I am pretty sure if u inject testosterone during puberty and make it so that u have very high levels like 1000-1200 ng/dl that a guy would end up with a big dick anyway.

It's hereditary, in that our physical characteristics are mainly a result of the genes passed down from our parents. However, you aren't just inheriting the determinative genes of your parents but those from your ancestors, all in various combinations.

My cock is much smaller than my father and brothers. Maybe one of my great-grandfathers had a teeny wienie. I do have Native American blood somewhere down the line, and I hear they're on the small side, so that might explain it. Much more believable than that a female ancestor of mine had sex with a chipmunk.

What I would like to know is whether the gene for dick size is in the Y chromosome or not. If that's the case, then a hung guy can only pass on his big dick size to his male offsprings, who in turn, could only pass theirs to their own offsprings.

If for example, Bruce Venture would have a daughter, she won't be able to pass on the big dick size to Bruce's grandsons.

Honestly. Shits weird

I don’t know how genetics work but both of my younger brothers are bigger than me.
We grew up sharing a bedroom so there was nowhere to hide

penis size is genetic, but it’s a little more complex than your parent having a smaller/bigger/hairier peen so yours will turn out like that, too.

Here’s what you need to know.


penis at all.

People assigned male at birth (AMAB) inherit the Y chromosome from a parent who was born with a penis, just like people assigned female at birth (AFAB) inherit the X chromosome from a parent who was born with a vulva.

As far as sex organs go, all fetuses look the same up until the seventh week of development.

After that, testes and all the rest start developing thanks to that Y chromosome.

But the Y chromosome doesn’t necessarily determine the type of penis you’re packing.

Your other parent’s contribution, your own unique genes, and other factors (more on those in a minute) play into your penis size, shape, and other features.

And yes, there are several types of penises.

average-sized penis from the other. It’s basically a crapshoot.

And before you ask: Yes, even twins can have different-looking Ds.

All that said, family members do tend to have similar features. While it isn’t guaranteed, there’s a good chance that you and your siblings share some similarities down there.



[paste:font size="5"]
Masturbation isn’t a factor in penis size either. It’s just a myth that frequent solo sex will make your D smaller or bigger.

Now that we’ve got that out of the way, let’s take a look at some factors that can actually influence size.

[paste:font size="4"]Your genes
We all have traits — or phenotypes — that are individual to us.

For example, you could have a turned-up button nose even though your parents’ noses lean more to the toucan side of the spectrum.

These traits could be the result of what’s called de novo genes. Everyone has these gene mutations, though how many varies from person to person.

These are genes that have changed slightly from your parents’ line and are all your own.

Exactly how these genes are born is still a bit of a mystery, but we do know that they can influence your physical traits — including your penis size and overall appearance.

For instance, you and your parent may share a similar length and girth, but yours could lean left while theirs hangs right.

Hormones
Hormones play a role in your penis size from the start.

Androgens determine penis size during early fetal development. Throughout puberty, testosterone and growth hormone regulate penis growth, including length and girth.

It isn’t just the hormones your body makes that affect penis size, though. The hormones you’re exposed to in your environment while your body is developing also impact penis size.

But instead of making your D bigger, these hormones have the opposite effect — not that penis size matters in bed, but still.

Exposure to environmental estrogens — aka a female sex hormone — during puberty has been linked to shorter-than-average penises.

Chemicals called endocrine disruptors can also have a negative effect on your penis. And the rest of your body, for that matter. These chemicals are found in things like pesticides, plastic containers, and some detergents.

Poor nutrition
Malnutrition in the womb and during the first few years of life can impact hormones and affect your growth and development.

We aren’t just talking your height and weight — organ development, including your reproductive organs, can also be affected.

study found the average growth rate to be less than half an inch per year from ages 11 to 15, but this isn’t set in stone for every peen.

You don’t have any control over it anyway, so try not to stress.

stop growing a year or two later than that, depending on when puberty starts.

For reference, puberty usually begins between the ages of 9 and 14 and lasts up to 5 years or so.

2014 studyTrusted Source, the average penis is 3.6 inches long while flaccid and 5.2 inches erect.

Try not to get too hung up on the number. For starters, the study only looked at a small portion of the world’s penis-wielding population.

Also, most people believe they’re smaller than average when they’re not. In reality, around 95 percent of people with penises do fall within the average range.

Finally and most importantly, size doesn’t make a diff where it matters most, which is in the bedroom… or backseat of a car… or the airplane lavatory…

organ) is the size that it is and there’s nothing you can do to make it bigger or smaller, aside from surgery.

Penis stretching exercises may increase size temporarily, but any evidence of this is anecdotal and doing it wrong could cause damage.

It’s possible to create the illusion of a bigger or smaller dick. Shaving your pubes so your D is on full display can make it appear bigger. On the flip side, a full bush can appear to shrink your D if you’re worried that it’s too long.

Your best bet is to learn to make the most of what your parents — or de novo genes — gave you.

The right sex positions can help you make the most of your size so you and your partner get off right.

[Hakan1]

it can be but not always. so basically I say no

 

[Hakan1]

How do all these guys know the penis size of their fathers, grandfathers, and brothers? Surely they don't have family get-togethers for measuring. This seems very odd.

you never went swimming or took a pee outside with your father or your brother ? It don´t always have to be something sexual. If you have a normal relationship with your father or your same sex siblings it´s very normal to see each other naked sometimes. At least where I come from.

 

[fireman1294]

Hell yeah it is, especially in my family it is. My dad had a big thick cock and handed it down and his brother had a baby dick and handed it down. Lol. At a family reunion skinny dipping gone wrong it was painfully obvious which son and grand son belonged to which brother

 

[53107]

It’s definitely hereditary. I know my bro is 8 + I’m 7.5 or just under 8. My Dads girlfriend said he had a big dick and was fishing to know if we were packing as well. I don’t know how big he is, but apparently really big

 

[deleted1168963]

I never saw my fathers dick but my brother’s dick seems to be on the thing side and average girth (he got up to pee when we were camping and I saw his hard dick as he got out of the sleeping bag. My and I work out together. Unless he is an amazing grower I say he’s a lot smaller than me

 

[pappiepapie]

I havent seen those of my own father and brothers but given that we share other physical traits i wouldnt know how it couldnt be. I have seen dads and sons naked that were incredibly alike, even when of course there are exceptions with some guys taking more after their moms family. But that's genetics all the same.

 

[yng_hung_london]

WHat I can report: My dad was bigger than me, that may be because he had a massive foreskn and i remember it from when i was a kid. But im pretty sure it was bigger than mine.

The cousin on my father side I sucked off is 17cm, which is stil very big and fills my mouth just right.

The other two, I sneaked in the shower they seem much smaller.

 

[Perfectsix]

Genetics must play a part but it’s obviously complex as both my younger brothers are really well hung and I’m…not

 

[Littleone68]

My father was small like I am but my brother is above average. Not sure where my brother got it from, never saw my grandfather nude.
