This article is about the animal sexual posture. For the human spinal shape and disorders thereof, see Lordosis.
Lordosis behavior (/lɔːrˈdoʊsɪs/[1]), also known as mammalian lordosis (Greek lordōsis, from lordos "bent backward"[1]) or presenting, is the naturally occurring body posture for sexual receptivity to copulation present in females of most mammals including rodents, elephants, and cats. The primary characteristics of the behavior are a lowering of the forelimbs but with the rear limbs extended and hips raised, ventral arching of the spine and a raising, or sideward displacement, of the tail. During lordosis, the spine curves dorsoventrally so that its apex points towards the abdomen.
