What Are Back Dimples? (Dimples of Venus/Apollo)

Definition and Appearance

The human lower back contains dimples which form as two small delightful pits visible in certain individuals. These indentations exist above the buttocks space at a distance between 2 to 4 inches from one another. Back dimples produce a lovely symmetrical pattern when they become visible on the lower back area.

Dimples of Venus represents a medical term used to describe these indentations which only occur in women. The same dimples are known as “dimples of Apollo” among male individuals. There is no distinction between back dimples based on gender because they remain identical across both sexes.

Where Exactly Are They Located?

To find back dimples:

• Look at the lower back area
• The dimples exist above the beginning of buttocks.
• The dimples can normally be observed at the height where a pair of pants would rest on the waist.
• The dimples become more prominent when the individual bends their body forward.

What Causes Back Dimples?

The formation of back dimples occurs because of the manner in which skin connects to deeper structures nearby. The underlying process that creates back dimples appears as follows:

• Skin Connections: This body region features an exclusive connection between the skin and pelvis structures.
• Fascia Attachment: The superficial fascia which is a thin tissue layer creates minor skin tension.
• Natural Variation: Individual bodies naturally form back dimples without causing the same effect in others.

Who Gets Back Dimples?

The population shows back dimples in their skin at a rate of between 20-30%. They’re:

• More common in women than men
• Often run in families
• Visible in people of all ethnic backgrounds
• More noticeable in people with lower body fat

Are back dimples permanent features of the body?

Once someone develops back dimples these features will stay permanently yet their appearance may fluctuate based on different periods.

• More visible when you’re leaner
• The presence of back dimples becomes harder to detect when your body weight increases.
• Don’t fade with age
• Don’t change position over time

What Is a Sacral Dimple?

Definition and Appearance

The base of the spine shows a small single indentation which rests where the back meets the top of the buttocks. Some sacral dimples extend below the skin surface while back dimples are always visible on the surface of the skin.

Location Details

You can find a sacral dimple:

• Directly over the sacrum (tailbone area)
• Right above the buttock crease
• Usually exactly in the midline of the body
• The area around the dimple may be accompanied by a small patch of hair.

What Causes Sacral Dimples?

The formation of sacral dimples happens during the early stages of human development. Possible causes include:

• Normal Skin Folding: The skin develops normally in this fashion during human embryological development.
• Mild Spinal Variation: Mild Spinal Variation appears only in rare cases while producing minimal changes to the spinal cord.
• Unknown Factors: The medical field sometimes encounters situations where doctors remain unable to determine specific origin points.

How Common Are Sacral Dimples?

They occur in:

• About 2-4% of all newborns
• Equally common in boys and girls
• The condition exists in adults who possessed it during infancy.
• The condition does not appear due to ethnic background or hereditary factors.

Key Differences Between Back Dimples and Sacral Dimples

To really understand these two types of dimples, let’s compare them side by side:

Feature	Back Dimples	Sacral Dimple
Number	Usually two (one on each side)	Typically just one
Location	Lower back above buttocks	Very bottom of spine
Depth	Always shallow	Can be shallow or deep
Visibility	More noticeable in adults	Often noticed in babies
Gender Link	More common in women	Equal in both genders
Genetic Factor	Often runs in families	Not strongly inherited
Health Meaning	Never a concern	Usually fine, sometimes needs checking

The Genetics Behind Back Dimples

Is There a “Dimple Gene”?

Scientists have not yet discovered a single genetic source of back dimples yet research shows:

• They tend to run in families
• Children tend to inherit back dimples when their parents display this trait.
• Several genes combine their activities to make back dimples appear.

Ethnic and Racial Differences

Dimples on the back exist in every human group although research shows specific patterns.

• Research indicates back dimples appear more frequently in specific groups of people.
• Every ethnic group features these traits among its members.
• Back dimples do not appear on the basis of what race someone belongs to.

Can you determine if a newborn will develop dimples before birth?

Scientists have not yet discovered a method to accurately predict their presence.

• When both parents have dimples in their skin the new baby is more likely to develop them too.
• An ultrasound scan cannot show dimples before birth.
• The dimples emerge as the child develops.

Medical Aspects of Sacral Dimples

When Are Sacral Dimples Concerning?

Doctors examine sacral dimples to detect three warning signs which are usually harmless but need medical attention.

• Depth more than 5mm
• Associated hair tufts
• Skin discoloration around it
• Any fluid drainage
• Connection to other symptoms

Possible Associated Conditions

Deep sacral dimples occasionally link with these conditions:

• Spina bifida occulta (mild spinal cord variation)
• Tethered cord syndrome
• Dermal sinus tracts

Diagnostic Tests Doctors Might Use

If concerned, doctors may order:

• Ultrasound (for babies)
• MRI scan
• Physical examination
• Neurological tests
