    • 1930 June, CD Veler, “The preparation of the crystalline follicular ovarian hormone: Theelin”, in Journal of Biological Chemistry, page 357:
      The isolation of the crystalline hormone seems to justify the selection of a new name which should be reserved for the crystalline material and which in reality becomes the name of a new and probably hitherto unknown chemical substance. Accordingly, we suggest the term “theelin.“ This word is derived from the Greek word “theelus” used both adjectively and nominally to signify “female.”
