Document Summary
Biological sex = physical anatomy and characteristics aka what organs you have. Sex differentiation = begins 8 weeks into development: 1) gonads = ovaries and testes, primordial cells are bipotential (indifferent) but default is female. Wolffian duct = male duct system, not bipotential, secretes testosterone and mis = mullerian-inhibiting substance. Mullerian duct = female duct system, not bipotential, ovaries develop, wolffian duct regresses due to lack of testosterone, mullerian duct is retained because there is no mis: 3) external genetalia = If testes present, testosterone with enzyme 5-alpha reductase will convert into dht. 5 alpha reductase = turns testosterone into dht. Dht = a very strong androgen hormone: 4) sexual maturation = puberty, when you become physiologically capable of reproducing and when you develop secondary sex characteristics, 5) culture. Turner syndrome = x, develop as female but other complications develop (ex. shorter stature, learning disabilities), none life threatening, 1 in 2000.
