Manning is currently serving a 35-year sentence at a military prison at Fort Leavenworth, Kan., for her role in the largest intelligence leak in United States history.
The day after she was sentenced, she announced she had gender-dissociation and was granted permission to receive treatment for the early stages of gender reassignment.
She is allowed to wear women's underclothes and shoes, and she'll start undergoing psychiatric and psychological counseling, two senior U.S. defense officials said Thursday.
