プロンプト

Create an anatomically accurate, photorealistic medical visualization of the external male genital anatomy of a fictional adult male, approximately 30 years old, with a neutral presentation and no sexual context. Show the anatomy clearly and unobstructed for educational and anatomical reference, including the penile shaft, glans, foreskin where anatomically present, frenulum, scrotum, and testicles. Use realistic human proportions, natural skin texture, subtle pores, anatomically correct pigmentation, realistic vascular detail, and physically accurate tissue structure. The subject should have a natural adult European appearance, neutral body presentation, neutral facial expression if the face is visible, and a clinical anatomical-reference composition. Use soft, neutral studio lighting, a clean light-gray background, accurate shadows, high-resolution photorealistic rendering, sharp anatomical detail, realistic skin subsurface scattering, and scientifically accurate proportions. Medical textbook quality, clinical anatomical reference, photorealistic 3D medical visualization, anatomically correct, highly detailed, natural proportions, neutral composition, no erotic posing, no sexual activity, no exaggerated anatomy, no fantasy anatomy, no artificial enlargement, no text, no watermark.
