x. Nervous system

The sexual response in the case of genital arousal and orgasm can be regarded as a reflex. The n. pudendus is the most important afferent nerve pathway in this process. The efferent arm of the reflex loop is an interaction between somatic, sympathetic and parasympathetic nerves. These reflexes extend over various spinal segments and are virtually insensitive to sex hormones. The spinal reflex loops are controlled by various higher centers that either inhibit or stimulate. Our knowledge of this is as yet limited, however.
