Testes — generative member

Essential generative organ

The testis marker represents the generative member that the Canon lists alongside the principal organs in its classification of members. It is placed in the lower-body field for visual legibility, with a wide uncertainty radius that avoids turning a historical generative category into a precise modern anatomy.

Ibn Sīnā (Avicenna), al-Qānūn fī al-ṭibb (The Canon of Medicine), Book I (primary_canonical)

Book I, §123, classifies the generative organs and names the testis or ovary among the members concerned with continuation of the race; the section does not prescribe the normalized lower-body coordinate used here.

Historical study of Islamic medicine's Galenic and Arabic developments, including Avicenna's humoral framework and Canon reception; it supports historical context but does not supply this normalized body diagram.
