Structure of the Developed Breast

Prior to puberty, the structure of the breast tissues is exactly the same in both females and males. Once a girl reaches puberty, her ovaries start to produce high amounts of the female sex hormones - estrogen and progesterone. These have direct relevance with the growth and development of a girl's breast tissues.(3 Trusted Source

In the structure of a fully developed breast, there are approximately 20 groups of lobes. These are glands that take care of producing milk at the time of pregnancy. Each lobule is in fact, an individual milk producing zone having a small tube leading from it called a ductile. The ductile links up to a wider tube called the ducts, which eventually open on to the surface of the nipples. Overall, the nipples will have about 20 of these duct openings which will activate during pregnancy.(4 Trusted Source

In between the lobules, there is a mixture of fatty tissue and tough supporting tissues. This maintains the shape of the breast as there are no muscles or bones making up the structure of the breast. The supporting tissues link up to the muscles of the chest wall underneath.


On the outer surface of the breasts one can find the nipple surrounded by a darker skin called the areola. The color of the areola can differ from one woman to another. It can range from dark shades of browns to a bright fleshy pink. The areola can also differ in size which can range from being extremely small and may not be readily visible or it could even spread to a wide area around the nipple.

What classifications are these? "Perfect breast shape" doesn´t sound scientific. The official breast types [IBSS] don´t define any "perfect breast shape". If you mean the breast type most people see as the most attractive, it is the U.S. Type of Breasts, but that type is not identical with what you call "perfect breast type". The U.S. Type of breasts have typically upwards pointing nipples, while here you talk about "parallel to the ground"? Its better to keep to the official breast types to avoid confusion.


This article was clearly written by a misogynist. The 'perfect breast'!? My god! This article sounds like it is from the 50s!


how to get rid of Swooping Breasts. i am tired of it.


I remember I read this article probably two years ago which made me realize my breasts are "constricted or tubular", or according to Medindia, "severely deformed" and "surgery is suggested". Thank you for making the first description I ever read about breasts that resemble mine to be "severely deformed" and suggest surgery. Whoever wrote this article obviously has 0 concern for anyone's self esteem. CHANGE THE WORDING of your description so you don't make any more young girls feel any MORE ashamed than they already are about their "severely deformed breasts". There are a LOT more women with this problem than documented due to the shame and embarrassment involved. Your article makes it 20 times worse. Asshole.
