Back dimples, formally known as fossae lumbales laterales, are anatomical indentations found on the lower back. These small depressions are situated symmetrically, one on each side of the spine, just above the buttocks. They are formed where the skin is tethered to underlying structures, specifically by short ligaments connecting the skin to the posterior superior iliac spine, which is part of the pelvis. These dimples are positioned directly over the sacroiliac joints, where the sacrum bone meets the ilium of the pelvis.
Understanding Their Occurrence and Origin
Back dimples are a naturally occurring anatomical feature that individuals are born with, indicating a genetic predisposition. While the exact genes responsible have not been extensively researched, evidence suggests that the presence of these dimples may follow a dominant genetic trait. These indentations are considered a benign anatomical variation and carry no medical implications for an individual’s health. They are distinct from sacral dimples, which are single indentations typically found lower down, just above the crease of the buttocks, and which can, in rare cases, be associated with underlying spinal conditions. Back dimples are a relatively common cosmetic feature, observed in both males and females, though they tend to be more prevalent and visually apparent in women.
Distinctive Features of Back Dimples
Back dimples typically present as two small, rounded indentations. The depth and prominence of these dimples can vary among individuals, influenced by factors such as body composition.
Historically, these features have been given informal, culturally inspired names. In women, they are often referred to as “Dimples of Venus,” named after the Roman goddess of beauty. When present in men, they are sometimes called “Dimples of Apollo,” referencing the Greco-Roman god associated with male beauty. This nomenclature reflects the aesthetic appeal often associated with these anatomical markings.
Separating Fact from Fiction
Numerous misconceptions surround back dimples, particularly regarding their connection to health or physical capabilities. Contrary to popular belief, these dimples are not indicators of good health, physical fitness, or enhanced circulation. Claims that they signify better orgasmic potential due to increased pelvic blood flow lack scientific backing. The formation of back dimples is purely structural, involving ligaments connecting skin to bone, and is unrelated to circulatory function.
Individuals cannot develop back dimples through exercise, specific diets, or other lifestyle interventions if they are not already genetically predisposed to them. Since there are no muscles in the exact location of these dimples that can be toned, exercise cannot create them. While losing overall body fat may make existing dimples more noticeable by reducing subcutaneous fat in the area, it does not generate them anew. Surgical procedures exist that can create the appearance of back dimples by selectively removing fat and tethering the skin, but these are artificial interventions.
