Sexes Most beings in the galaxy belonged to one of two sexes , or genders — namely male or female — which determined sexual and physiological traits . However , more than four genders existed throughout the galaxy . Biological and cultural significance . Many sentient and non - sentient species had male and female sexes , with many biological and childbearing similarities between the two . Human s and other humanoid lifeforms generally reproduced by the coupling of a male and female , from which the female would give birth to male or female children . A female could have multiple children over her lifetime and some were capable of giving birth to several at once . Complications during pregnancy could be disastrous for a female , resulting in permanent disability or death . The children inherited the genetic traits of both their parents , and could also inherit Force - sensitivity . In modern , developed societies , nanny droid s or other supervisors could care for children if their parents were unable to spend enough time with them . Not all species exhibited typical mammalian breeding and childbearing patterns . Some species , such as the Neimoidian s , were born as grubs and forced to compete over a limited food supply . Others hatched from eggs , such as the Geonosian s , who all came from a single hive queen . While most individuals exhibited male - to - female attraction , a significant minority of the galactic population exhibited male - to - male , female - to - female , or male - to - male / female attraction . Some planets , such as Chandrila , were home to unprejudiced cultures , allowing such individuals to make public displays of affection free from the threat of physical violence . However , some still felt awkward and embarrassed when openly conveying such affection . Some individuals viewed sexual encounters as nonbinding , participating in them recreationally . However , many throughout the galaxy considered such lifestyles unusual , and looked down upon those who practiced them . Despite this , several such individuals existed within high society , such as Moff Delian Mors . Galactic impact . Throughout galactic history , the human species ' ability to rapidly reproduce resulted in its dominance as one of the most populous races in the galaxy . During the Clone Wars , male humans were cloned from the bounty hunter Jango Fett to form the Grand Army of the Republic . These clones were grown in hatcheries on the planet Kamino , and were genetically altered to accelerate their growth rate and to be more compliant to orders . Owing to geopolitical or economic hardship , many male and female members of a variety of species sold themselves as prostitute s or " mistresses " to a variety of clientele . Largely looked down upon , such activities often occurred in areas of ill repute , and could result in exploitation , rape , and slavery . Many who frequented such venues were gamblers , spacer s , or spice addicts who lacked stable relationships , or were rich and otherwise influential persons , normally in positions of considerable political power . The Twi ' lek species was largely regarded as one of the most beautiful species in the galaxy , resulting in numerous slaver s capturing females from the Twi ' lek homeworld of Ryloth . Among the Galactic Empire ' s military personnel , the euphemism " off - base recreation " referred to soliciting in cantina s or visiting various " mistresses . " Popular locations for these activities included the Octagon in Ryloth ' s capital city , Lessu , or the Coruscant underworld . During the Empire ' s reign , the Imperial Loyalty Officer Sinjir Rath Velus , in order to more effectively interrogate a subject , often sought to discover the subject ' s sexual companion . Droid s , being machines , lacked a biological sex . However , in order to appear more lifelike , many droids were programmed with a " masculine " or " feminine " personality . Thus , even mechanical beings were designated either " he " or " she " .
