What Are Boobs And Other Trivia

What are boobs and are they all the same? Breasts are beautiful and unique in their own unique way! No breast is ever the same and comes in various sizes and shapes! Here, learn more interesting facts about boobs.

One breast is typically smaller

Natural breasts are not symmetrical. One breast is typically about a fifth bigger than the other. If you’re curious, the left side typically has the size advantage. Despite frequently varying in size, two breasts typically have a comparable density and structure.

Breasts contain a lot of fat

Each breast has a complex network of glands and channels, including your nipple, and is supported by muscle and fibrous tissue that separates it from your ribs. Breast tissue and the majority of your breasts are formed of fat. When you drop pounds, a lot of the weight you lose overall will come from your boobs. However, after a certain age, your breasts do start to become primarily fat.

Want bigger boobs? You can try putting on weight

A woman’s weight can significantly affect the size and form of her breasts. Weight affects the quantity of fatty tissue within the breasts, and gaining weight causes the fatty tissue to expand and increase their size. Other factors, such as pregnancy, breastfeeding, menopause, birth control pills, and even sex, can make your breasts swell.

Your breasts can also grow up to a full cup size during your menstrual cycle. Days after your period, however, your hormone levels drop and your bustline is at its smallest due to hormones. Since some women have denser breasts with less fatty tissue, you might notice that your bustline shrinks.

You can’t stop sagging

Truth: Some breast sagging is unavoidable. Having a child, breastfeeding, and aging all lead to collagen losing its elasticity, which makes your breasts look more deflated than firm. Your breasts will sag as you age unless you have corrective surgery. Other causes include gravity, smoking, and sleeping. Sagging can also be a genetic issue.

Wear a sports bra when you exercise, your boobs will thank you

One study found that your breasts can move up to eight inches as you run (imagine making a figure-eight motion), so a supportive sports bra is beneficial!

Although exercising does not directly affect breast tissue, if you want firmer, perkier breasts, you can exercise and strengthen the surrounding chest muscles. 

A third nipple is not unusual

According to the Genetic and Rare Diseases Information Center, around 200,000 people have one or more extra nipples. However, 6% of people have extra breast tissue in their third (or more) nipples, and some of these extra breasts can even produce milk and become sensitive when a woman is menstruating.

The first breast augmentation was done in 1962

Breast implants are currently the most popular type of plastic surgery in the United States according to the American Society of Plastic Surgeons. Breast augmentation surgery dates back to the early 1960s when doctors Frank Gerow and Thomas Cronin developed silicone breast implants. It is believed that Dr. Frank Gerow got the idea for silicone-filled implants when he squeezed a plastic bag filled with blood and remarked that it felt similar to a woman’s breast.

Humans are the only primates with permanent breasts

Humans develop breasts before puberty and our breasts continue to develop and change throughout our lifetimes. They get engorged especially during menstruation and when we are pregnant. Other primates only have one type of permanent, fatty breast, which is called a femoral breast.

There are 4 types of nipples

Nipples can be described/ categorized into the following:  puffy, inverted, flat, and protruding.

A breast weighs between 1-2 pounds. 

Typically, natural breasts weigh between one to two pounds. However, according to the Guinness Book of World Records, the woman with the largest natural breasts in the world wears a size 52i bra. Her breasts weighed approximately 100 pounds.
