Taresia is the homeworld of the Taresians, a mostly female society that lured men there to use their DNA for reproduction.
Taresia is a planet in the Delta Quadrant inhabited by the Taresians, whose population is overwhelmingly female. To reproduce, they draw genetic material from males, many of whom are taken from other species and altered with a retrovirus to believe they belong there.
In Favorite Son, Voyager fled to Taresia when attacked by the Nasari, and the Taresian leader Lyris welcomed Harry Kim as a son returned home. The Taresians raised a polaron grid to cut Kim off from the ship, but he discovered the truth and escaped with the help of his crewmates.
