Here’s a breakdown of what it actually means:
1. The Anatomical Facts
These indentations are called “Dimples of Venus” (or sacral dimples). They are:
-
A natural, hereditary anatomical feature.
-
Created by a short ligament stretching between the spine and the skin.
-
Located where the posterior superior iliac spine (PSIS) of the pelvis meets the sacrum. They essentially mark the location of your sacroiliac joints.
-
Not gender-specific. While often called “Dimples of Venus” (the Roman goddess of love), men can have them too (sometimes called “Apollo’s dimples” in that context).
2. What They Do Not Mean
-
They are NOT a sign of a medical condition (in their common, shallow form).
-
They are NOT an indicator of fertility, fitness level, or anything mystical, despite many social media claims.
-
They are NOT “holes” into the body, but simply superficial skin indentations over a bony landmark.
3. Important Medical Distinction: Sacral Dimple vs. Pilonidal Dimple
This is crucial to understand:
-
Normal “Dimples of Venus” are shallow, symmetrical, and located higher up on the lower back.
-
A Pilonidal Dimple/Sinus is a small pit or tunnel in the crease between the buttocks, near the tailbone (coccyx). This type can be prone to infection (pilonidal disease) and is a different structure altogether.
4. Why The Trend Exists
On social media (especially platforms like TikTok and Instagram), these dimples are often sexualized or presented as:
-
A rare “beauty mark” or sign of attractiveness.
-
A supposed indicator of good circulation or back strength.
-
A topic for engagement-driven content, leading to exaggerated or false claims.
In summary: If you see these two indentations on a woman’s (or a man’s) back, they are a normal, common anatomical feature marking the location of the pelvis and spine. They have no special meaning beyond genetics and anatomy. While they can be aesthetically highlighted in fitness or fashion, any claims about them indicating something about health, personality, or fertility are not scientifically based.
If someone is concerned about any dimple, especially one that is new, deep, red, tender, or draining fluid, they should consult a healthcare professional to rule out any underlying condition.
