Excargan

The Excargans were a race of near-humans native to Excarga and were affiliated with the Galactic Republic and later with Galactic Empire. During their childhood years, it was unknown if they were male or female. Around an Excargan's thirteenth birthday their bodies would change and their sex would be determined.
