An interesting article comes our way detailing how stress may effect the size and growth of a woman’s breasts.
Typically during puberty a woman’s hormones begin to gradually build up, resulting in the development of breasts and other characteristics of sexual dimorphism. More specifically, it stimulates the growth of the subcutaneous fat and mammary glands that make up the breasts.
This is especially the case when a woman becomes pregnant and her hormones become far more vigorous, thus resulting in a sudden increase in breast size.
However, the pituitary gland from which these hormones come from is incredibly delicate in regards to stress.
During puberty, engaging in rigorous club activities or extreme diets can put the utmost amount of stress on the pituitary gland and heavily suppress female hormones.
An example of this pattern is said to be marathon runners, who go through a great deal of stress and then experience a runner’s high afterward, from the endorphins released by the pituitary gland. They are also not known for being well endowed…
Via Otona Magic.
Perhaps a lack of activity is key to large breasts? Or maybe just a lax diet. Curiously, several developed nations with obesity problems also possess large average breast size…
If all else fails, there’s always the surgical alternative.

I'm not sure this makes sense. I mean, Konata doesn't seem to have a stressful life.
If that would be true, I would have enormous breasts and not a flat chest.
please god relax the wemon of this world cause I needs me some big oppai:)
I don't know why everyone is all about big boobs. Personally, I love smaller boobs (oppai?). Give me an A-cup or a nice B-cup and I'm in heaven! More is just wasted.
But that's just my opinion!
amen brother if it doesnt fit in ur hands, excess is waste, i love small boobs, please be proud of ur body's gals, cause flat chest isn't bad, its better big boobs - back ache...
I'm going to start going to the track to look for chicks now.
FUUUUUUUU I can't stop the jizz from exploding in my pants.........
*Right Click-Save* FMFGJ!!!!!
No wonder I'm small-chested.
So it took this kind of article to finally make the girls drop their lurking coat? I'm so happy...
How many commenters announce their gender, except when commenting on such topics? I don't really think it qualifies as lurking...
I'm a girl, and I visit this site about daily.
よろしく!
I also visit here daily, but I'm also a dyke, so it's kind of a win-lose situation for most of you.
Well I'm a Dutch Boy so it's still a win-win for me... :P
It doesn't matter ... welcome, anyway!
I don't usually go out of the way for 2D chicks, much less flat-chested ones (I'm all too aware that I'm in the minority here), but there's something about whoever that is in the headline image that's genuinely attractive.
Well, breasts are essentially lumps of fat. The less body fat, the smaller the breasts. Though I have seen fat women with flat chests.
Just today I was learning how toxins affect hormones, and that girls with high levels of toxins in their body tend to have larger breasts. It could be what the women are doing to deal with the stress that is of importance.
So I just have to stress out a girl to get smaller breasts? That's some good info. Might come in handy.
hm. i started breast development at an early age, currently have C cups, and i was physically active + fairly stressed.. so i guess this research is proving to be a bit of a.. BUST. *ba-dum-pish*
i'm sure breast size is mostly reliant on genes.
It's weird b/c I have a B-38 or C-cup and I do alot of sports since I was a kid and was a tomboy too but now half... Still I have a bit stress like who doesn't and part of my dads side have mostly flat chested & my moms side is a 50% flat N 50% with big ones so I don't belive what their saying b/c they have no prove.. I always wonder why are like 92% of asians have it so small but their are ones that have big ones not conmen no offince >..<
Not all stress is equivalent.
The stress of losing a father can accelerate development of secondary sexual characteristics.
Well, that explains most of japan.
I'm always stressed out. My rack should be hella small.
this explains why in 'futaba-kun change' futaba-chan's breasts have grown bigger after the first time it was measured. lustful thoughts on the mind lol
there was an article in a medical journal in the early 17th century discussing how the author (whose name i don't know) had done extensive testing and he found that chicken increases breast size...
This was pre-America and pre-KFC as well, so i am to assume that the increased breast size was isolated from an increase in any other parts :P
This has obviously been proven false since, as their is no modern scientific basis for such a thing... amusing idea though...
This means that we must keep them stressed out at all times to increase the flatness! D8<
OK if someone already posted this im sorry... but wow the reason marathon runners have smaller breasts is because they have little body fat, which also creates shorter and lighter periods and in some cases a lack of one. and yes places like America are known for larger girls with large breasts but this is because breasts are fat.... although the amount of animal steroids in American meats might have something to do with it too...
Yeah, back when Japanese ate only fish they missed out on most of those extra animal hormones. When Americaand Europe introduced red meat, they also introduced oppai to Japan.
Curse you, southern barbarians!!
Is it just me, or does this kind of apply to anime?
Some of the lazy girls I see usually have big breasts while the flat chested (& sometimes little, but not the age to be considered lolicon) tend to be the "RAAAAAHHH, I HAVE ANGER & STRESS, FEAR ME!" kind of girls (i.e Taiga from ToraDora).
Not that I'm saying that this is true for all anime girls, just something that I've noticed.
It's been a while since I've read something so void of scientific relevance.
"Prolonged loss of the target organ hormones of LH and FSH, i.e. estrogens in women and testosterone in men, may cause loss of body hair, osteoporosis, and reduction in breast size in women."
LH and FSH levels effect ovulation. When some women get very stressed out they can skip a period, however most continue their ovulation as usual.
This stress is often due to hormonal imbalances in the body, not the other way around.
When the hormones go hay-wire it is not out of the question that some women will decrease slightly in cup size... but thats about as common as a girls hair falling out at 20 and her skipping periods.
I'm not saying it doesn't happen, i'm just saying it's not going to be the difference between a B-cup and Double-D's.
if you want to connect something to breast size, try looking up drug abuse.
What about those advice the girls in anime always get?
'Drink lots of milk and sleep more'
This is why tsundere characters have small breasts.
... The logic is amazing.
:O
niiiiiice logic....
And that is why theres so many lolicons running around :D
No doubt about that
Why didnt you told us sooner!! You could save so many girls lives!!
Indeed, I have to agree with her. Take for example the avg. boob size for women in my country was B. However, during most of our generation (for a host of reasons) the size has increased to C. Although, it does seem interesting that I see more women around that are naturally sporting bigger chests than that. Yes, plz stay as stress-free as possible ladies.
It's the increase in consumption of dairy products. The cows get growth hormones to increase udder size (to increase productivity) which then leak into their milk. Oh, and there are also natural growth hormones contained in every mammal's milk, meant for the calf. So when in Asian countries the dairy consumption by female children and teenagers went up, their average breast size increased as well.
OK, mandatory mega milk diet for all young females!
Moar growth hormonez, pls!
Big or small as long as it's a 100% girl.
"Perhaps a lack of activity is key to large breasts? Or maybe just a lax diet.Curiously, several developed nations with obesity problems also possess large average breast size"
Breasts are made of mostly fat, so usually(but not always) more fat= bigger boobs. I've heard stories of women going down 1-2 cup sizes after losing weight.
Women tend to lose weight in their breasts FIRST when on a diet.
You want big breasts on your gal, that means she's going to need a lot of body fat--- and to keep her weight, or only lose weigth very gradually. Even then, it will come more out of breasts first then other areas.
THEY ACTUALLY GO DOWN?! I always thought its up and never down....
Lol I think it's one of the things that women hate about dieting... their breast sizes go down along with their waist size/weight.
Hey, I'm always more than happy to help carry them :D
Some women really hates having large breast size because it's hard to carry them around as they say. Maybe losing a few pound is not that bad.
Weren't Soifon's breasts pretty big?? Not Orihime big...but realistically big.
See the bust chart:

7 is Kotetsu Isane(assistant captain 4th co.)

Correct. Can't remember either of their names right now though as they haven't appeared in the manga for quite some time.
