Anatomy and Design
Children are born with penises and testes are often raised with the expectation that they will identify as men, although intersex children may also be assigned to this identity while possessing some but not all of the above characteristics, Men may be cisgender (assigned male at birth and identifying as male) or transgender (assigned female at birth, yet identifying as male).

Identifying as a man is often associated with male sex characteristics such as a penis, testes, narrow hips, a prominent Adam's apple and a low-pitched voice, as well as a masculine gender expression and gender role, but these are not neccessary, and it is still possible to identify as a man without them.
