Whether someone has these dimples is influenced mainly by genetics and body structure. They can be visible in both women and men, although in men they are sometimes called Apollo dimples.
Despite popular claims online, Venus dimples do not reliably indicate better circulation, fertility, sexual health, or physical fitness. Some people simply have them naturally, while others do not.
They require no treatment and are not a sign of illness. However, a new painful indentation, swelling, redness, or other unexplained change in the lower back should be evaluated by a healthcare professional.
