During embryogenesis, [[Sexual Differentiation - Anatomy & Physiology#Sexual_Differentiation_of_the_Brain|sexual differentiation]] occurs, during which the brain is programmed to be either male or female.  In most mammals, reproductive behaviours are [[Sexual Differentiation - Anatomy & Physiology#Sexual_Differentiation_of_the_Brain|sexually differentiated]].  For example, [[Copulatory Behaviour - Anatomy & Physiology#Mounting|mounting]], [[Erection - Anatomy & Physiology|erection]] and [[Copulatory Behaviour - Anatomy & Physiology#Ejaculation|ejaculation]] are typically male behaviours, while standing to be mounted ([[Receptivity Behaviour - Anatomy & Physiology|lordosis]]),crouching and elevated locomotion are typically female behaviours.  These behaviours are endocrine controlled, the presence of gonadal steroids (oestrogen and testosterone) is obligatory for normal reproductive behaviour.
