One thing that struck me as interesting in Masters of Sex episode 2.03, Fight, was that Bill Masters had a genetic test on hand that determined definitively that the baby with ambiguous genitalia was male.
Watson and Crick first published the structure of the DNA double-helix in 1953. Was Masters really determining sex by a simple blood test in 1959?
This article on the WHO website says
In 1959, chromosomal analysis of two human disorders, Turner syndrome and Klinefelter syndrome, demonstrated for the first time that genetic factors on the Y chromosomes of mammals are important determinants in male sex.
Seems like an anachronism to me.
