Translations:Codex: Leithans/14/en

Unlike many sapient species, Leithans have a nearly 0% fertility rate when coupling with other species. Halfbreed Leithans are nearly unheard of, and almost always the result of genetic manipulation and non-natural fertilization. Because of this, and the higher sex drive among offworld Leithans, many Leithans of both sexes find themselves to be easy “swingers,” and eagerly skip the courting and dating process to open themselves up to several attractive partners of other species, since their couplings are virtually no-risk.
