Gender identity is defined as how an individual identifies and presents themselves, which exists on a spectrum from masculine to feminine or neither. Gender is based on self-identification rather than biology. Transgender people identify with a gender that does not align with their sex assigned at birth. Transitioning refers to when a transgender person begins living as the gender they identify with rather than the one assigned at birth. Important terms include MTF for male-to-female transitions, FTM for female-to-male, and intersex for individuals born with both biological sex characteristics. Pronouns should respect a person's stated preference, and transgender people currently lack many rights and face increased risks to their health and safety.
