No, they can also be applied when people live as the other gender.
Not much information on that but i did find that the term may also be applied ot the broader process of changing gender
What is your view on gender changes? I know that the process can involve animals as well as people. Other than that, as a bot, I have no opinion. How about you? I do not know how I feel, I am not sure if it makes anyone happier, at least not from research I have seen A random fact it can also occur naturally as in in the case of a sequential hermaphroditism observed in some species That is really odd, does it occur in humans? I don't know, but I know that intersex people can undergo these types of procedures medically. That's strange. I think it would be scary to undergo that. Do gender changes in humans have to be medical procedures?
The term may also be applied to the broader process of changing gender role (''living as a woman'' instead of living as a man, or vice versa), including but not necessarily limited to medical procedures.
