Ibn Sīnā (Avicenna), al-Qānūn fī al-ṭibb (The Canon of Medicine), Book I (primary_canonical)
Book I, §123, distinguishes generative members from the material and faculties involved in generation, including semen in the discussion of generative functions; the text does not prescribe a normalized semen point.
