Final answer:
The term for a person who was designated male at birth and identifies as a male is 'cisgender'. This aligns with their sex assigned at birth and is separate from sexual orientation or gender expression.
Step-by-step explanation:
The terminology used for a person who was designated male at birth and identifies as male is cisgender. This term comes from the Latin prefix 'cis-', meaning 'on the same side'. Cisgender individuals have a gender identity that aligns with their sex assigned at birth. It is important to note that being cisgender does not determine a person's sexual orientation or gender expression. Cisnormativity often excludes recognition of those who have gender identities that differ from their sex assigned at birth, such as transgender individuals, who may identify opposite to or outside of the traditional binary gender categories. Additionally, there are people who may adopt a variant gender identity that does not conform to the binary notion of male or female.
