Pronunciation

  • UK: /tɛˈstɒ.stə.ɹəʊn/[1]
  • US: /tɛˈstɑ.stəˌɹoʊn/[1]

Etymology

It is borrowed from German Testosteron, coined in 1935 by K. David and his colleagues in the “Zeitschrift für physiologische Chemie”,[2][3] from Latin testis (“testicle”), sterol and the chemical suffix -one.[3][4][5][6][7] Barnhart, Merriam-Webster and Dictionary.com treat it as an English formation from the same parts, with the connecting vowel -o-;[5][6][7] the Oxford dictionaries analyse the ending as -sterone, a blend of sterol and ketone.[8][9][2] Klein takes the first part from testēs, the plural of testis.[10]

Earliest recorded meaning

A steroid hormone that brings about the development of male sexual characteristics, produced mainly in the testes: 1935, in Chemical Abstracts.[2][11][3]

Semantic evolution

From 1937 the name was also used for its propionic ester, testosterone propionate, given by injection as a longer-lasting form of the hormone.[2][12] Merriam-Webster also records a figurative sense for qualities such as brawn and aggressiveness thought of as typically male.[13]

Timeline

  • 1935 – German Testosteron, and the English word in Chemical Abstracts.[2][3]
  • 1937 – testosterone propionate.[2]
