Comment: Notions in words like life, death, wellness, or love incorporate timeless universal notions represented by mythic figures, emblems, icons, legends, ballads, and lullabies. In a way, such complex notions are like an Egyptian cartouche - a capsule of a cluster of ideas represented by a word (continued at the end of the following list of words). Suggestion: in addition to alphabetic search, if needed, add "word search" in this page (press control F) fuRTHERMORE, the whole Pandora Word Box is dedicate to illuminate meanings conveyed by images and words.

   medical literature uses this term to describe, in most instances, ovo-testes or "mixed
   gonadal dysgenesis" (a high cancer risk anomalies thus an indication for surgical
   removal of such gonads). Pseudo-hermaphroditism, male variety (feminized males)
   and female variety (masculinized females). Personally, I find such "labels" offensive,
   degrading, arrogant, dogmatic and socially damaging. Personally, since the causes
   and pathogenesis of such disorders are multiple and complex, an acceptable alternative
   may be to describe actual clinical features as kindly as possible; gynecomastia for
   example does not have to be branded as an instance of "feminized male" or a large
   clitoris be branded as in instance of a pseudohermaphroditism or equally offensive
   branding as an instance of a "masculinized female". (more in an Overview on this

============
Comment continued: ... While etymology seeks to uncover linguistic roots of words, ideonomy seeks to illuminate clusters of ideas inherent in words. Perhaps a "play with words" such as "what is the idea in the notion of idea" may be a way for others to learn from you answer, what is "on you mind". 

What follows is an informal repository of brief definitions of medical terms with an emphasis on their inherent "ideas". More expansive presentations often are presented in the format "Word Ideas", as "Overviews", and other alternative styles. The access to these entries can be secured by a general search of the contents of Pandora Word Box by using particular key words.
