Hormones were one of the biological substances that connected a being's mind and body to each other, along with oxygen, nutrients, and neuron health. Stimulating the brain through physical exercise affected the connections.
By the time twenty years had passed since the Sith rebellion, hormones were a medical supply utilized by some beings. Yuehiro, a Force-sensitive Twi'lek male and apprentice of the Jedi lord Hanrai's , took hormones when he was fourteen years old. While he was a passenger on the Poor Crow, a starship owned by the female pilot Ekiya, she told him where to find the ship's medical supplies to assist his peers. When Yuehiro asked her about hormones for himself, she was able to provide some from an emergency stash kept on the ship by her friend, the male slicer Shogo.
Hormones were first mentioned in the current Star Wars canon continuity in the novel Thrawn, written by Timothy Zahn and published in 2017.
The use of hormones as a medical treatment was introduced in the non-canon Ronin: A Visions Novel, written by Emma Mieko Candon and published in 2021 as a tie-in to the Star Wars: Visions short film "The Duel." Candon confirmed through social media that the hormones are hormone replacement therapy used by transgender individuals.
