In sexuality, the process of changing from one sex to the other, with or without medical intervention. For most, transition is a gradual set of changes over time. It may be difficult to determine exactly when a transition begins and when it ends. Some feel that their transitions began the day they started hormone treatment. Some feel it began when they told their loved ones about their identities. Some feel it began when they changed their names legally. Some feel they are "in transition" for a few years until their hormonal changes settle in. Some feel that their transitions end when they are legally recognized. Some feel their transition is complete when they have completed genital reconstruction surgery.
