We all have them. Breasts. But do you know everything about them? Most probably you don´t, as breasts have so many different social and physiological functions.
Here are 18 interesting facts you may not know:
1. Breasts normally grow for about two to four years after a girl gets her first period.
Breast growth is stimulated by the female sex hormone, estrogen. The final size of breasts is based on the genetic heritage of the individual.
2. In many women, the left breast is usually slightly larger than the right.
Globally, up to 20 % difference in size between the right and left breast is considered normal in most countries. However, Caucasian US women have more symmetrical breasts with less volume variation between right and left breast.
3. Breasts signal you are fertile.
The physical appearance of a woman´s breasts has a high impact on the interpretation of her sexual attractiveness. Most studies show that men rate women with the largest breast sizes as the most attractive.
Large breasts signal female sexual maturity as women with large breasts have higher estrogen levels than women with smaller breasts.
Breasts are the most obvious Female Secondary Sex Characteristic. In this role breasts act as well visible indicators of the sexual and reproductive capacity of a woman.
4. You can reduce the risk of breast cancer in many ways.
Women can reduce the risk of breast cancer by watching their weight, quitting smoking, exercising regularly, being restrictive with alcohol, and avoiding menopausal hormone replacement therapy.
5. US women have larger breast size than women born in other countries.
At the age of 28 to 30 years the average Caucasian US woman has a breast volume of 1 668 ml per breast, or 3 336 ml in total. The average US woman wears a size 40 DD bra (or about 40 F/G in EU sizing).
6. Nipple color changes during pregnancy.
Hormones released during pregnancy can often make nipples darker. They fade later again.
7. Go for mammography at the age of 40 at latest.
For those without a high genetic risk of breast cancer the American College of Obstetricians and Gynecologists recommend that annual mammograms are done starting at the age of 40 years.
8. Your breasts have an important role in your interaction with other women.
A woman´s breast size correlates positively with her social prestige. Not only men, but also women place women with large breasts high on the attractiveness scale. This gives women with larger breasts a socially dominant position. Women with smaller breasts tend to behave in a submissive way in social situations with women who have larger breasts than theirs.
In other words, large breasts are a great advantage for you, if you want to become a team leader and manage people.
9. Bra standards vary as breasts come in lots of different shapes and sizes.
The average breast size and shape varies a lot between countries. The same applies to bra sizing; bra labelling varies remarkably between the countries and manufactures.
The international IBSS Standard was created for the commercial needs of the lingerie industry as an effort to align product sizing over the country borders. It divides breasts into 16 different breast types. It is mainly used for R&D, so the actual labeling sizes vary still a lot between the countries.
There is also a commercial resistance against globally aligned bra sizing as women in no country want to buy the cup sizes A or B, if there is an alternative on the market. Therefore, bra makers prefer to have smaller sizing in markets where women have a small average breast size. Manufacturers simply do not want to loose customers to any competing brand that is using smaller sizing scale. Even a small breasted Asian woman in the Far East prefers to buy a bra brand with locally adapted sizing instead of a brand with European – or not even to mention – American sizing. Buying a locally labelled 36 DD bra makes her feel much more confident than buying a bra brand with American sizing and leaving the store with a pathetic 36 AA.
10. Breast augmentation with implants is the most popular plastic surgery procedure for women.
For example, just in Brazil 250 000 women get implants every ear. In China, Europe, Russia and the Far East the demand for augmentations has been increasing rapidly for years. Women all over the world, including Asia, want to have large round implants to get breasts resembling the hemispherical and large breasts of US women.
11. Smoking makes breasts saggy.
Smokers have more saggy breasts than non-smokers due to the chemicals in cigarettes breaking down the body’s elastin.
12. US women have commonly round and firm breasts.
IBSS Standard recognizes the US Type of Breasts as a distinguished breast type common in Caucasian US women. In comparison to other breast types, the US Type of Breasts are large and firm with a pronounced hemispherical shape. The nipples point up from the horizontal level and they are commonly located above the horizontal center of mass.
13. Many women are wearing wrong bra size.
As many as 80% of us are wearing the wrong size bra and as well as effecting the way your boobs look, it could also be damaging your health, leading to back pain, indigestion and even headaches. It is a good idea to shop bra at a lingerie specialty store instead of supermarket.
14. Even small breasts can feed a baby.
Most women with small breast size produce enough milk to feed an infant. Healthy food, regular daily schedule and long enough breast feeding sessions help to meet the nutritional needs of the baby.
Most of the time, the milk production capacity of small breasts becomes a limiting factor only for milk donation or feeding of several infants.
15. Breasts have always been popular in art.
In European pre-historic societies, sculptures of female figures with highly exaggerated breasts were common. Artifacts such as bowls, rock carvings and statues with breasts have been recorded from 15,000 BC all across Europe, North Africa and the Middle East.
Phoenician goddess Astarte was represented as pillars studded with breasts. The Egyptian goddess Isis was often portrayed as suckling pharaohs.
Female breasts were also prominent in the Minoan civilization and in Ancient Greece; there were also several cults worshipping the suckling mother.
16. You can make cash by donating breast milk.
At least if you are a US woman, there is good chance you can earn a nice sum by selling your breast milk. The US Type of Breasts have an unmatched milk production capacity thanks to their high content of milk gland tissue. The breasts of this type have commonly 28 milk gland lobes (20 – 36), while other breast types have only 12 – 20 milk gland globes.
If you have the US Type of Breasts in your bra, it may be a great idea to invest in an efficient breast pump, as you can not only feed your infant/s, but also deliver very large amounts of milk for donation and earn tens of thousands of dollars.
17. Breastfeeding is increasing in the USA.
The breast-feeding rate has been increasing by an average of 2 percentage points per year. Breast feeding is most prevalent in the West, with Idaho, Washington, Oregon, and California containing the largest percentage of mothers nursing for the highest number of months.
18. Too aggressive exposure of breasts may hurt the feelings of your friends.
Social media is very rewarding for women with large breasts. If you are busty, it is understandable you may want to show your figure in online profile updates and blog messages.
However, you should share photos of your female body shape cautiously to avoid hurting your female friends. Think about that you are presenting the most visible Female Sex Characteristic. You may be busty, but not all of your friends are as lucky as you.
Do you think it is appropriate for man with a large penis to build his social media presence exclusively around the close-ups of his bulging boxer shorts? Probably you don´t. There is a direct analogy between the penis and breast exposing behaviors. Growing penis size is an obvious Male Sex Characteristic, while growing breast size is a Female one.
After all, a bulging jeans leg front of a man in a full body shot gives a pretty good understanding about what he has got. In the similar way, you don´t need to fill your social media pages with breast close-ups to show off what you got. Normal full and half body shots and a few holiday pics are enough to signal your rivals where you stand in relation to them.
Think about that even fully clothed photos of your busty body may hit hard the self-confidence of women with smaller breasts. What you think is an great selfie to share on Facebook or Instagram, may easily be experienced as a humiliation by your less busty friends. In particular, be careful so you don´t add any comments or tags that may be interpret as derogative by those of your friends who have smaller breasts than yours.
If you are lucky to be busty, make sure you share, tag and comment the selfies showing your female appearance cautiously to avoid hurting your less lucky friends. Think about that breasts are the most visible Female Sex Characteristic. Even your fully clothed selfies may hit hard the female self-confidence of women with smaller breasts. What is a great selfie for you, may be seen as a personal humiliation by your less busty friends.
