When did cisgender become a thing?
While transgender dates to at least 1970, cisgender is a child of the 1990s: our evidence dates it back as far as 1994. It got its first element from a prefix that means “on this side,” from the Latin cis or citra, which has the same meaning.

Women who have borne children have scars on the surface of their pelvis. The femur (thigh bone) of a male is thicker than a females.
Is there a difference between male and female muscles?
there are major differences between female and male skeletal muscles, including differences in energy metabolism, fiber type composition, and contractile speed (7, 11, 19, 23, 33).
