An American father and daughter who've both struggled with their respective gender identities are transitioning together from mother and son.
Corey Maison, who is 15, told her family four years ago that she identified as a girl.
Last year, Eric, who used to be her mum Erica, came out identifying as a man, 9News reported.
In an interview with Australian current affairs show 60 Minutes, Eric spoke of his trepidation after his revelation but was inspired by Corey's brave decision.
"The first feeling was relief, the second was terror," Eric said.
"Fear of what my future would hold, fear for how my family and children would react, fear for what the rest of my life was going to look like."
Despite the monumental changes to their family structure, the Detroit family are sticking together.
Eric's husband Les told 60 Minutes that he is "still married to the same person I married".
"I fell in love with the person," Les said.
"That's really all there is to it."
