Sexes / Legends Most beings in the galaxy belonged to one of two sexes , male or female . However , some species , such as the Hutts , could adopt the sexual characteristics of either sex , and were classified as hermaphrodites . Other variable species , like the X ' Ting , changed sexes periodically based on hormonal cycles . Some alien species had more than two sexes , such as the insectoid Xi ' Dec , which had over 180 . Finally , some species , like the Filordi , were asexual , with individuals being able to reproduce on their own . The Fnessian race had a previously undocumented sex called Thos . The Rakririan s also had a third sex , known as facilitator drones . Hermaphrodites . A number of species reproduced hermaphroditically . For instance , individual Hutts contained both male and female reproductive organs . Other hermaphroditic species included the Pui - ui , the Verpine , and Strill s . Another example of a hermaphrodite species is the Vratix . A Vratix individual would , during its life assume both the role of impregnator and gestator " male " and " female " , depending on its age . Dimorphism . Most species possessed distinct characteristics that distinguished males and females . Females tended to have slighter frames than males and possessed voices with a higher pitch and tonal quality . Females of most mammalian and some reptilian species were distinguished by their breasts . Social practices also further characterized female gender roles by how they were expected to act , the clothing they wore , and how they were expected to style their hair , if their species grew it . Males tended to be larger , with broader shoulders and deeper voices . Males had more muscle mass and were expected to perform better with manual labor than females . Social practices set gender roles that expected those that identified as male to behave in certain ways , wear certain clothing , and style their hair in a way that was considered " masculine " in order to further differentiate that gender from the females of the species . Exargan sexes were undetermined in their youth , with both males and females having similar features . Around their thirteenth birthday , an Exargan ' s sex would then develop . Droid gender programming . Droids , especially those with complex personalities and those which worked in close partnerships with organic beings , such as protocol droids and astromech droids , were often programmed to have stereotypically masculine or feminine personalities . Thus , even mechanical beings were usually designated " he " or " she " . Behind the scenes . Several " Star Wars " games allow the player to choose the sex of the main character where that character exists in canon . Characters such as Rookie One , Jaden Korr , Revan and the Jedi Exile all fit into this category . Since " Star Wars " has a definitive story , subsequent publications have decided the sex of these characters in " Star Wars " continuity . Since their introduction , Rookie One , Revan , and Jaden Korr were all canonized as male , and the Jedi Exile was confirmed as female . Some games , such as " Star Wars Galaxies " , allow the player to choose the sex of a controlled character that does not get tracked in continuity . Although these characters are not considered to be a part of canon , many of the in - game events are . The characters who take part in these events are referred to as " spacers " on Wookieepedia .
