Breasts are organs made up of adipose (fat) tissue and connective tissue. Within these tissues is a system of arteries, nerves and lymph nodes / vessels. Ligaments connect the breasts to the body. Underneath the breasts are the pectoral muscles, which sit on top of the rib cage. (But breasts themselves do not contain .)
The distinct, circular region of skin surrounding the nipple is called the areola.
Beneath the areola are milk ducts which deliver milk to the nipple. The milk ducts are connected to 15 20 lobes and mammary glands (also referred to as lobules), which generate breast milk (mainly) in nursing women.
Below is an image that depicts the human body of female breasts:

What’re Mammary Glands?
Mammary glands are modified sweat glands that are found in both men and women. Mammaries normally just function in women who are lactating (producing milk to nourish a baby) but technically, guys have that skill too.
What are the differences between male and female breasts?

Man vs Female Breast and Nipple
Male breasts are nearly indistinguishable to female breasts. It’s a little known fact that guys, just like girls, possess mammary glands. While it rarely happens, you’ll find men who have the skill to lactate and breastfeed.
Despite the anatomical similarity, male and female breasts are viewed quite differently in America. This really is mainly because of an overriding social and cultural relationship between female breasts and sexuality.
As previously stated, female breasts are not sex organs, but they are often viewed as sexual objects. Breasts are hypersexualized. They’re used to sell all types of different products and to serve heterosexual male delight. But at the same time, girls are shamed into covering them up. In reality, women are shamed even when they’re trying to breastfeed, which will be the primary biological function of breasts.

Both men and women (and people of any sex) can derive sexual pleasure from their breasts and nipples. A man’s naked torso also can just as easily inspire lust in the opposite gender (or the same sex). This fact is generally discounted because society tends to blow off female sexual desires and will condemn sexual women by slut-shaming them. Most of the mainstream media in the USA is focused on the sexual desires of straight men. (This is unsurprising when you consider that most films, TV shows and other media is directed and created by men and for men.)
Aside from torso hair, male and female breasts usually are not that different in appearance. Some men have larger breasts than certain women, which is frequently pointed out by supporters of topfree equality for girls.
The biggest difference between a male and female breast is that one is sexualized and fetishized while the other is not. Breasts are not sexual in and of themselves. It truly is our society and culture that sexualizes them.
Human Breasts in America:
What’re considered “ordinary” breasts?
If we went by what we find in the media, we’d believe “normal” female breasts are absolutely round, symmetrical, perky, with smooth skin, little pink nipples and large in size (or at least big enough to form a noticeable cleavage). Male breasts in the media are always muscle, well defined, chiseled and nearly flat.
But that is not reality! There’s no “regular” standard for men or women. Breasts, nipples and areolae come in all shapes, sizes and colours.
They are able to be very small with the nipple being the most defining attribute, others may be quite substantial and protrude a couple of inches from the body (and all sizes in between). Breasts can be round, cylindrical, sit high on the torso or droop down lower and they may be all ordinary.
Breast size also does not necessarily correspond with body type or size. Bigger girls may have little breasts and skinnier girls can have large breasts. (Losing or gaining weight can impact breast size, but it depends on a person’s fat tissue and genetic make-up. In any case, they will just change up to a point and it is generally not a severe increase or decrease in cup size.)
Areolae and nipples differ in color and size. come in all different shades of pink and brown. The size of the areola or nipple does not depend on breast size. Big breasts can have small areolae or nipples and vice versa. Nipples may also be “inverted,” which means they retract inward. This can be standard and can be seen on both men and women.
It’s really common for girls to have asymmetrical breasts, where one is larger than the other (even one cup size larger).
“Sagging” is also quite common and completely normal. The skin that holds the breast will, over time, naturally assume a lesser hanging standing due to gravity and skin elasticity.
When it comes to breasts, the great majority of variations are perfectly normal and should not be any reason for concern.
Why do breasts fluctuate so considerably from person to person?
The different types of tissue in breasts, our muscle / fat composition and hormones can all change and they all discover what our breasts can look like. Or the easier answer is: genetics.
For girls, breasts additionally change throughout their lives and go through smaller changes during fertility / menstrual cycles. (* However, experts warn that any sudden change in breast texture, size, shape or appearance should be reported to your physician promptly, as these might be signs of breast cancer or other potentially serious health problems.)
The picture below is from Laura Dodsworth’s book, Naked Reality. She photographed 100 women from all walks of life and requested them to share their stories about their breasts and bodies. The book investigates many themes in relation to women’s breasts, for example body image, sexuality, equality, breast cancer, femininity, what this means to be a girl, and more.
It’s an amazing piece of work that illustrates the diversity of women’s bodies and women’s perspective on them.
