Hyposexuality is a lack of sexual drive, interest, or activity. It may be associated with many diseases, physical or psychiatric, and/or medications which affect the central nervous system. Along with hypergraphia and hyperreligiosity, hyposexuality is one of the defining features of the Geschwind syndrome.
