Sperm was a biological substance involved in the reproduction of certain species, during which it was often paired with ova.[1] In several species, sperm was produced by males and inserted into females. For instance, male sarlaccs attached to females as parasites and fed their sperm into their mates.[2] Females of the ghest species of the planet Rodia could even access the sperm of a dead male and self-inseminate, leading to the laying of fertilized eggs.[3] Among the gra species, genetic engineering by sentient beings was so extensive that gra sperm and ova were sold with instruction manuals.[1]

In other species, the same individual produced both sperm and eggs. For instance, the silicon-based shadow barnacle of the planet Coruscant released both egg seeds and sperm pollen into the atmosphere to reproduce.[2]
