The gluteofemoral crease, also known as the gluteal fold or infragluteal fold, is a term used in anatomy to describe the natural indentation between the buttocks and the thigh. This groove serves as a distinction between these two body parts. Though mainly called the gluteofemoral crease, the term is not widely known or used in everyday language. Therefore, alternative synonyms for this anatomical feature can be utilized, such as "buttock crease", "buttock-thigh crease", or simply "buttock fold". These terms help to provide a clearer and more widely understood description of this natural contour.
